What's actually in the box
| Item | Specification |
|---|---|
| Grow tent | Light-tight box 40 × 40 × 120 cm, 600 D mylar canvas, reinforced steel frame |

Why pick the BloomLED Top Budget Pack
🌱 Full spectrum tuned for veg AND bloom
The SpectraBULB X30 mixes deep red, blue, warm white and IR wavelengths to cover the entire cycle from seedling to harvest. No need to swap bulbs between phases: a single LED carries your plants all the way through.
⚡ Tiny power draw, real output
30 W of well-placed horticultural LEDs do the work of an 80 W fluorescent tube. Across a full grow cycle, the pack draws under 35 kWh — around €7 to keep a mother plant healthy for 90 days.
🔌 Plug-and-grow, no DIY needed
E27 cable with switch, ceramic socket, EU-standard plug: screw in, plug in, switch on. No wiring to pull, no ballast to install, no cooltube to fit.
🧊 Cool to the touch, low stress on plants
Where a 250 W HPS sits at over 200 °C, the BloomLED horticultural LED stays warm at most. Your seedlings won't scorch, your tent stays comfortable and the extractor barely has anything to evacuate.
🇫🇷 Designed in France, tested in France
BloomLED designs its bulbs in La Rochelle, manufactures them to spec and tests every batch before shipping. Returns are handled by our French support team — no offshore call centre.
📦 Everything you need, nothing you don't
Many "complete" packs forget the pots, the clamps or the duct. The BloomLED Top Budget Pack ships with every part — there's nothing else to buy before your first power-on.
Who is this pack for?
The 40 × 40 footprint is the reference format for starting indoor growing without committing to a full setup: it fits in a wardrobe, under a stair, in a quiet corner of an office. It's also ideal for keeping a mother plant, mass cloning, or maintaining culinary herbs through winter. For flower runs, plan 1 to 2 plants depending on training. If you need more, our 80×80 and 100×100 packs sit further down the page.
👉 The most complete starter LED grow pack under €250, ordered as one SKU — no cart-juggling, no missing parts.
Setup: 4 steps, under an hour
1. Tent — Unfold the steel frame and clip the bars. Slide the mylar canvas around, zip it shut. 2. Ventilation — Mount the extractor at the top, run the duct to the exhaust port. 3. Light — Screw the SpectraBULB X30 onto the E27 cable, hang it 30–50 cm above the canopy. 4. Substrate — Fill the pots, drop in your clones or seedlings, plug everything in. Switch on the LED. Done.
Frequently asked questions
One to two flowering plants depending on training (LST, SCROG, mother plant). For cloning or culinary herbs, you can fit 4 to 6 young plants. Rule of thumb: one mature plant per 0.1 m². The 40×40 is 0.16 m², which leaves room for a well-trained mother plant or two short-flower-cycle plants.
Is 30 W of LED really enough for a full grow?Yes, as long as you respect the surface-to-power ratio. Across 0.16 m², 30 W of high-efficiency horticultural LED delivers about 200 µmol/m²/s of PPFD at canopy centre — consistent with vegetative growth or light flowering. To boost flower yields, add a second SpectraBULB X30 or move up to one of our larger packs.
Does the LED run as hot as an HPS?No, and that's the whole point. A 30 W LED produces less than 25 W of effective heat versus 250 W or more for a 250 W HPS. You can hang the bulb 30 cm above the canopy without burn risk, and the included extractor easily holds the tent at 24–26 °C under full load.
Is the pack discreet? How much noise does it make?The tent is light-tight (600 D mylar canvas + reinforced zips). The included extractor is sized for a 40×40 and runs under 30 dB on its lowest speed — about as loud as a whisper. For even more discretion, add a soundproof box or a carbon filter at the exhaust.
What happens if the SpectraBULB X30 fails?2-year BloomLED warranty. Send the bulb back, we test it within 48 h on our French premises and ship a replacement. Support is in French/English, reachable by email or phone, and handled directly by the BloomLED team — no offshore middleman.

Looking for a compact, reliable and easy-to-assemble indoor grow tent? The Hydroshoot 40×40×120 cm V2 by Secret Jardin ticks every box: rugged Q195 steel frame, ultra-reflective 210D Mylar lining (95%), waterproof zipped door and leak-proof floor tray. Ideal for cuttings, keeping a mother plant alive or running a discreet mini-flowering cycle in a flat.

| Specification | Value |
|---|---|
| External dimensions | 40 × 40 × 120 cm (footprint 0.16 m²) |
| Reflective fabric | 210D Mylar, ~95% light reflection |
| Frame | Q195 steel tubes Ø 16 mm — 0.5 mm wall thickness |
| Hanging load | 10 kg on cross bars |
| Vents | Ø 150 mm air outlet with sleeve + cable ports |
| Sealing | Light- and water-tight (sealed bottom tray) |
| Net weight | 2.6 kg |
🌱 Built for clones and mother plants
The 40×40 cm footprint is the sweet spot for 6–12 cuttings or a single mother plant without giving up a whole room. The 120 cm height fits a small LED panel plus inline fan with breathing room.
💡 High-reflectance 210D Mylar
The diamond-pattern 210D Mylar liner sends roughly 95% of the light back onto the canopy: every lumen from your horticultural lamp is converted into stronger growth and yields.
🛡️ Light- and water-tight build
Reinforced zip door, light-trap stitching and a sealed bottom tray: no light leakage into the room and any watering spill stays inside the tent. Maximum peace of mind indoors.
🔧 No-tool assembly
Q195 Ø16 mm steel tubes with pre-labelled connectors: one person sets up the tent in just a few minutes. Disassembly is just as easy when you need to store it between cycles.
Aim for 80–120 W of real LED draw (quantum board or COB) to cover clones and veg. For flowering, 120–150 W is plenty. Don’t oversize: heat builds up fast in 0.16 m².
Which fan and filter pair with the Hydroshoot 40×40 V2?A Ø125 mm inline fan rated 180–280 m³/h paired with a Ø125 mm carbon filter is more than enough. The Ø150 mm outlet also lets you upgrade to Ø150 mm gear for quieter operation. Add a small clip-on fan for canopy airflow.
Can I use it in a flat without disturbing the neighbours?Yes. Light- and water-tight construction prevents visible leaks. Combined with a properly sized carbon filter and a quiet inline fan, the Hydroshoot 40×40 stays discreet — perfect for a closet or small room.
BloomLED’s pick: compact yet seriously equipped, the Hydroshoot 40×40 V2 is our favourite size for getting started in indoor growing without overspending. Sturdy, leak-proof, signed Secret Jardin — a long-term investment.

Tips for using the SpectraBULB X30


SpectraBULB X30 is a LED bulb with a total power consumption of 32W. This high performance bulb is coupled with 4 lenses of 50° which help guide the light flow to the plants.

The SpectraBULB X30 is equipped with 16 OSRAM 2W LEDs for perfect spectrum mixing. Thanks to its 100% optimized spectrum, the bulb focuses all the light on the plant, which considerably reduces light wastage outside the horticultural area. Its intensity is sufficient for a 50cm square in the growing phase (60cm distance) and 40cm in the flowering phase (50cm distance). The SpectraBULB X30 LED horticultural bulb produces a deep red, blue and white spectrum to bring out the different pigments in your plants.

Unlike other solutions, LEDs do not generate intense heat and have a very small thermal footprint. The SpectraBULB X30 is equipped with a heat sink and an ultra-quiet fan for optimal heat dissipation.

This SpectraBULB X30 LED horticultural bulb can be used on any stand with a standard E27 socket.

Light-Mix 20L Biobizz Soil Bag: The Ideal Substrate for a Successful Start under LED
At BloomLED, we know that the foundation of a successful indoor grow is a quality substrate. The Light-Mix 20L Soil from Biobizz is specially designed to provide your plants with an optimal environment from the very first stages of their life, in perfect synergy with the efficiency of your horticultural LED lamps. This light and aerated substrate is the key to vigorous rooting and healthy growth, without the risk of over-fertilization.
Biobizz Light-Mix is a premium growing substrate, renowned for its airy composition and low nutrient content. It's the preferred choice for indoor growers, whether experts or beginners, who want total control over nutrient input. Its unique formulation ensures excellent root aeration and perfect drainage, essential conditions for preventing diseases and promoting rapid, robust growth.
Why choose Biobizz Light-Mix for your LED grow?
Our experts at BloomLED, with over 10 years of experience in horticultural lighting, recommend this substrate for several key reasons:
- Total control over fertilization: Being "lightly fertilized" (not pre-fertilized), Light-Mix allows you to precisely adapt nutrients to the specific needs of your plants, thus avoiding stress related to over-fertilization, which is particularly crucial for young shoots.
- Ideal for seedlings and cuttings: Its fine and aerated texture promotes rapid and healthy rooting, giving young plants the best possible start under the intense light and full spectrum of our horticultural LED lamps.
- pH balanced: Light-Mix is pH balanced, which guarantees optimal nutrient absorption by your plants' roots. A stable pH is fundamental for fertilizer efficiency and overall plant health.
- Excellent aeration and drainage: The specific composition of this soil ensures an oxygen-rich root environment and prevents waterlogging, essential factors for vigorous growth and dense root development.
The 20-liter bag is a practical format for starting multiple crops or for growers with limited space. Pair it with our BloomLED horticultural LED lights for an efficient and energy-saving indoor growing system. Designed in France, BloomLED is committed to providing you with the best equipment for your passion.

| Volume | 20 Liters |
| Brand | Biobizz |
| Substrate Type | Light-Mix (lightly fertilized) |
| Recommended Use | Seedlings, cuttings, initial growth |
| Compatibility | Indoor growing under horticultural LED lamps |
| Composition | Peat, perlite, vegetable fibers |
🌱 Optimal Start
A light, non-pre-fertilized substrate, perfect for seedlings and cuttings, ensuring precise control of essential nutrients.
🌬️ Superior Aeration
Its unique composition ensures excellent air circulation to the roots, preventing asphyxiation and promoting robust growth.
💡 LED Synergy
Ideally suited for growing under horticultural LED lamps, it allows maximum absorption of the benefits of the light spectrum.
Light-Mix is particularly suitable for the seedling, cutting, and early growth phases. For more advanced growth and flowering phases, it is recommended to add appropriate nutrients or transplant into a more enriched substrate like Biobizz All-Mix, if you prefer less fertilizer management. Its advantage is giving you total control over your plants' nutrition.
What is the difference between Light-Mix and other Biobizz soils?The main difference lies in the nutrient content. Light-Mix is "lightly fertilized" (not pre-fertilized), giving you total control over nutrient input from the start. All-Mix, on the other hand, is a heavily pre-fertilized substrate designed to cover plants' needs for several weeks. Light-Mix is ideal for growers who prefer to manage their fertilization program from A to Z, especially for sensitive plants or young shoots.
The Light-Mix 20L Biobizz Soil is the number one choice for demanding indoor growers for a perfect start to their crops under horticultural LED. Unparalleled control for exceptional results!

🌱 Superior root aeration
The breathable fabric creates natural air-pruning: roots stop circling and instead split and colonize the whole substrate for far more efficient nutrient uptake.
💧 Flawless drainage
Excess water escapes through every inch of the pot wall. No more root rot from overwatering: your indoor grow becomes more forgiving and more vigorous.
♻️ Lightweight, foldable, reusable
It folds flat when empty, stores easily and handles multiple grow cycles. A long-lasting accessory for growers who care about their gear.
The 4L fabric pot is ideal for rooted cuttings, young plants in vegetative growth, or compact plants up to ~50 cm. For full flowering, step up to an 11L or 15L size.
Can Garden HighPro fabric pots be reused?Yes, that's one of their strengths. Between grows, empty the pot, shake it out and rinse with water (or machine wash at 30 °C without softener). It regains its breathability for the next cycle.
The 4L Garden HighPro fabric pot is the growshop standard: aeration, drainage and durability at a price low enough to kit out a whole tent or shelf.

Remember, proper ventilation is key to preventing common grow room issues and ensuring robust plant growth.
BloomLED Tip: Regularly check your grow room temperature and humidity with a hygrometer. Adjust your extractor fan's operation to maintain ideal conditions for your specific plant cycle. Consistent airflow is more beneficial than intermittent bursts.

Frequently Asked Questions
How do I know if this 190m³/h extractor is powerful enough for my grow tent?To determine if the 190m³/h airflow is sufficient, calculate the volume of your grow tent (Length x Width x Height in meters). You ideally want to exchange the air in your tent at least once every 1-3 minutes. For example, a 0.6m x 0.6m x 1.6m tent has a volume of 0.576m³. Multiplying by 60 (minutes in an hour) gives you 34.56m³/h for one air change per minute. This 190m³/h fan is significantly more powerful, making it suitable for tents up to approximately 0.8m x 0.8m x 1.8m for optimal air exchange, or even larger for less demanding applications like seedling propagation.
Can I use this extractor with a carbon filter?Yes, absolutely! We highly recommend pairing this PROFAN 125mm extractor with a 125mm carbon filter to effectively remove odors from your grow space. Ensure the carbon filter's maximum airflow rating is equal to or slightly higher than the extractor's to maintain efficiency.

Adjustable 25-175mm · Stainless Steel · Corrosion Resistant · Secure Fastening
Achieve perfect airflow and maintain optimal climate control in your grow space with the BloomLED Adjustable Stainless Steel Hose Clamp 25-175mm. This essential ventilation accessory ensures your ducting connections are not just secure, but also airtight and long-lasting, preventing costly air leaks and ensuring your extraction system operates at peak efficiency.

Why a Reliable Hose Clamp is Crucial for Your Indoor Grow
In the world of indoor growing, every detail matters. From the quality of your lights to the precision of your nutrient delivery, maintaining an optimal environment is key to healthy plants and abundant yields. Your ventilation system plays a critical role in this, removing stale air, excess heat, and humidity. A robust and reliable hose clamp is the unsung hero that ensures your entire system functions flawlessly.
Without secure connections, your ducting can sag, disconnect, or leak air, leading to:
- Reduced airflow efficiency
- Increased energy consumption
- Poor temperature and humidity control
- Potential odors escaping your grow space
- Compromised plant health and growth
The BloomLED Adjustable Hose Clamp is engineered to eliminate these concerns, providing a steadfast grip that withstands the demands of continuous operation.
Key Features of the BloomLED Adjustable Hose Clamp
Universal Adjustable Diameter (25-175mm)
Our hose clamp offers an incredibly versatile adjustment range, perfectly accommodating a wide variety of ducting sizes commonly used in indoor growing setups. From smaller 25mm (1 inch) ducts to larger 175mm (7 inch) systems, this single clamp provides a secure fit, reducing the need for multiple specialized clamps. This flexibility makes it an ideal choice for growers with varying equipment or those looking to upgrade their systems in the future.
Premium Stainless Steel Construction
Crafted from high-grade stainless steel, this clamp is built to endure. Unlike standard steel or plastic alternatives, stainless steel offers superior resistance to rust, corrosion, and degradation, even in the humid and often warm conditions of an indoor grow room. This ensures a prolonged lifespan for the clamp and consistent performance of your ventilation system, protecting your investment and your plants.
Secure & Easy Fastening Mechanism
Designed for both strength and ease of use, the robust screw-tightening mechanism allows for quick and secure installation. Simply position the clamp, tighten the screw with a screwdriver, and achieve a firm, airtight seal around your ducting. The reliable grip prevents slippage and accidental disconnections, giving you peace of mind that your ventilation system is operating safely and effectively.

Why growers choose this timer
🌱 Stable photoperiod, consistent harvests
18/6 in veg, 12/12 in bloom: set the tappets once and the cycle repeats identically every single day. A steady photoperiod reduces light stress and the risk of plants reverting to vegetative growth.
⚡ 3680 W: from one panel to a full room
With 16 A of headroom, this timer drives a single horticultural LED panel just as happily as a power strip feeding several bars, an extraction fan or a nutrient pump. Just keep the combined draw under 3680 W.
🔧 Mechanical means unbreakable
No display, no backup cell, no menu to reprogram after a blackout — the dial simply resumes turning when mains power returns. That is the raw reliability growers want when a tent runs unattended for months.
BloomLED tip: keep the 'always-on' position for low-PPFD cloning stages, then switch back to timer mode as soon as plants enter vegetative growth. A photoperiod drift of more than 30 minutes is enough to unsettle sensitive flowering varieties.
Frequently asked questions
Is this timer suitable for an LED grow light with a driver?
Yes. LED drivers draw a brief inrush current at start-up that the 16 A contacts of this model absorb comfortably. For multi-driver builds exceeding 1500 W combined, BloomLED recommends adding a power contactor and using the timer purely as the pilot signal.
How do I set a 12/12 flowering photoperiod?
Push down the tappets covering your desired lights-on hours — for example 8 pm to 8 am — then rotate the dial until the arrow points at the real current time. Finally slide the side switch to the clock symbol. Each lowered tappet equals 15 minutes of light.
