Built for indoor growers who want to multiply their plants without compromise, the Garden HighPro Probox Propagator L combines 720 cutting slots, a high-reflectivity 97% mylar lining and complete lightproofing in a footprint of just 60 x 40 cm. Curated and shipped by BloomLED, indoor-growing specialists for over 10 years, it delivers the stable, professional environment your seedlings, cuttings and young plants need to thrive.

Standing 200 cm tall while occupying only 0.24 m2 of floor space, the Probox Propagator L exploits vertical space like no other tent in its class. Its 5 fabric shelves attach with Velcro and reposition freely in height, so you can match the spacing to every growth stage: tightly packed seed trays at the bottom, airier young cuttings above. This modularity turns the Propagator L into a continuous-production workhorse, perfect for back-to-back plant rotations all year round.
Performance starts with the 97% reflective mylar lining. Combined with a tough 420D Nylon outer shell and a fully opaque zip, it guarantees a strictly controlled light cycle: no stray light leaks, even distribution to every shelf and optimised photosynthesis for vigorous young plants. Three Ø 13.5 cm ventilation ducts and two Ø 8 cm cable ports make it easy to add an extraction system, a heat mat or a propagation light, while the patented frame supports up to 36 kg of suspended load.

Five height-adjustable Velcro shelves hold up to 720 cuttings or seedlings, 144 per level, for large-scale indoor production in a minimal footprint.
The mylar interior bounces 97% of light back onto your plants, maximising photosynthesis and growth uniformity with no wasted light energy.
The opaque zip and 420D Nylon shell block every light leak, ensuring a perfectly controlled day/night cycle for your propagation runs.
Three Ø 13.5 cm ducts and two Ø 8 cm cable ports make it simple to fit an extractor fan, a heat mat or a dedicated horticultural light.
The patented Garden HighPro chassis carries up to 36 kg suspended, enough to safely hang an LED bar, a humidifier or a propagation dome.
The large 55 x 190 cm front door features a transparent window so you can watch your cuttings root without breaking humidity or the light cycle.
The Propagator L has 5 Velcro fabric shelves holding up to 720 cuttings in total, around 144 per level. You can remove or reposition shelves to grow taller plants when needed.
How does it differ from the Propagator M and XL?The Propagator M (80x60x40 cm) is a compact starter format, while the Propagator XL (120x40x200 cm) doubles the propagation surface. The Propagator L 60x40x200 cm offers the best height-to-footprint balance for a corner of the room.
What lighting should I use in this propagation tent?A low-energy horticultural LED with a growth spectrum is ideal for cuttings and seedlings. The frame holds 36 kg suspended and the cable ports simplify wiring. BloomLED offers LED solutions tailored to propagation.
Is the tent truly lightproof?Yes. The 420D Nylon fabric and the opaque zip provide complete lightproofing, essential for precisely controlling the day/night cycle of your young plants and avoiding light stress.
Is it easy to assemble?Yes, the patented Garden HighPro frame clicks together without tools. The shelves attach with Velcro straps and reposition in seconds to suit your needs.
