🛠 BloomLED expertise, designed in France

BloomLED has been developing horticultural lighting solutions for over 10 years. French engineering, technical support and manufacturer warranty.

Is this kit suitable for beginners?

Yes. The HomeLAB 40 kit is built for beginners: everything ships together, wiring is plug-and-play and the SpectraBULB X30 BL handles every growth stage without tweaks.

How many plants fit inside the HomeLAB 40?

The 40×40 cm footprint comfortably fits 1 to 2 plants in medium pots (5–11 L), or a mother plant for cloning. For more plants, step up to our 60×60 or 80×80 range.

Is the SpectraBULB X30 BL enough for flowering?

Yes for a 40×40 cm footprint. BloomLED's full-spectrum recipe is calibrated to deliver the wavelengths needed for flowering across this compact footprint.

Does the kit include ventilation?

No. This kit focuses on lighting, space and climate monitoring. To complete your setup we recommend a silent inline fan and a carbon filter sized for 40×40 — both available on BloomLED.

What is the electricity consumption?

The SpectraBULB X30 BL draws 30 W real. On an 18/6 veg cycle that is about 0.54 kWh per day — a controlled footprint that keeps your power bill in check.

🌱 Compact 40x40 footprint, 120 cm working height

Perfect for tight spaces — closets, laundry rooms, apartment corners — the HomeLab HL40 hosts one mother plant, 4 to 6 cuttings, or your ornamental crops. The 120 cm height leaves room for a compact LED grow light and vertical plant development.

🛡️ 700 µm Mylar lining — Total blackout

The high-density Mylar interior reflects over 95 % of the light back to your plants and delivers perfect darkness for photoperiod control. The thick waterproof outer shell blocks every light and sound leak.

🏗️ Reinforced steel frame — up to 50 kg

The 13-16 mm steel poles and metal connectors hold your LED grow light, extractor fan, carbon filter and accessories without flexing. The HomeLab HL40 stays stable even when fully loaded.

🌬️ Optimised ventilation — Ø 150 mm + MicroMesh

Standard 150 mm extraction port compatible with every fan and filter on the market. Air intakes are protected by MicroMesh fabric that blocks insects, spores and dust while letting fresh air flow in smoothly.

🇩🇪 Made in Germany by Homebox — Premium reliability

Homebox has been the European benchmark for grow tents for over twenty years. Every HomeLab HL40 is produced in Germany with strict quality control: reinforced stitching, YKK zippers, silent closures and lab-tested fabric.

Which LED grow light fits the HomeLab HL40 best?

For a 40 x 40 cm footprint, go for a compact 30 to 60 W LED grow light. The SpectraBULB X30 from BloomLED is perfectly sized: full spectrum, plug-and-play E27 format, ideal for cloning, vegetative growth and bloom in small volumes.

What extraction system should I use with this 40 cm grow tent?

A 100 to 150 m³/h extractor fan in Ø 125 or Ø 150 mm is more than enough to refresh the HL40 air. Pair it with a carbon filter if you grow aromatic plants: the Ø 150 mm port allows direct coupling without a reducer.

Can I use the HomeLab HL40 for cloning and seed starting?

Absolutely. The 40 x 40 x 120 cm format is ideal for a mini propagator, heating mat and a cloning LED like the SpectraBULB X30. Total blackout plus MicroMesh ventilation create a stable, clean environment for young plants.

Is the tent hard to assemble? How long does setup take?

Not at all. The HomeLab HL40 assembles in 15 to 20 minutes, tool-free. Poles click together, fabric attaches via reinforced zippers. You can also fold it back down easily if you need to move or store it.

The HomeLab HL40 isn't just a grow tent: it's the premium standard for compact indoor growing, trusted by serious growers and recommended by BloomLED's experts.

With its high-precision sensors, the Optithermo gives you instant feedback, allowing you to make timely adjustments to your ventilation, humidification, or heating systems. The convenience of an external probe means you can measure conditions precisely where it matters most – right at your plant canopy – without disturbing the environment.
