2m White Lightite (WBW) 120mu Lightproof Sheeting — Dual-Function Reflective Partition for Separate Growing Cycles
Best for: Growers who need to run two spaces with different light cycles in the same room, or want light-tight protection without compromise
Our thoughts
This is the clever bit of kit that solves a real problem — needing to run separate light schedules in one space without light leaking between them. British-made, properly constructed, and does exactly what it promises. One we sell a lot of for growers looking to maximise their room.
White Lightite (WBW) is a triple-layered reflective sheeting with a unique design: white reflective polythene on both sides, with a layer of black light-tight material sandwiched in between. This means you get complete light blockage in one direction while reflecting light back into your growing area from the other. It's the only sheeting that lets you partition a room and run two different light cycles simultaneously without one interfering with the other.
Made in the UK to consistent standards, it's supplied in 2-metre widths with a centre fold — so every metre you buy gives you 2 square metres of usable sheeting. Simple to hang with heavy-duty tape, no special installation skills needed.
How it compares
The reflective sheeting market offers several options. Here's where White Lightite sits:
-
Panda Film: Cheaper, decent reflection, but black-and-white only — can't separate two light cycles in one space. Degrades after a couple of years.
-
Mylar: Maximum reflection (up to 95%), but delicate, creases easily, and requires careful handling. Not light-tight between spaces.
-
Orca Film: Durable and reflective, but significantly pricier and still doesn't solve the dual-cycle partition problem.
-
White Lightite (WBW): The only option that combines 100% light blockage with dual-sided reflection. Unique. Built to last.
If you just need reflection, cheaper options exist. If you need to separate two growing spaces with different schedules, White Lightite is the answer.
Usage guidance
Partitioning two grow spaces
Hang vertically to divide your room. One side runs lights on schedule A, the other on schedule B — zero light leakage between them. The black centre layer prevents bleed-through completely. The white sides reflect light back into each space, so you're not losing efficiency.
Window sealing and light control
Use to black out windows or seal light leaks. Hangs flat against walls or windows with heavy-duty tape. The reflective exterior bounces ambient light back out; the black interior stops it coming through.
Grow room wall lining
Line walls, ceilings, or anywhere you need to redirect light back towards your plants. Increases light efficiency by over 30% compared to bare walls, which also helps reduce energy costs. The white reflective surface scatters light evenly; the triple-layer construction means it lasts longer than single-layer alternatives.
General benefits
The food-grade material is plant-safe and won't off-gas. The reflective properties help reduce mould and algae growth by optimising light distribution and air circulation. Dead simple to install — just tape it up.

Who this is for
- Growers running mother plants and flowering plants on different schedules in one room
- Anyone needing to seal windows or light leaks without sacrificing reflection

Our take
This solves a real problem that standard reflective sheeting can't touch — you get complete light separation and efficiency in one product. It's British-made, straightforward to use, and built to last longer than cheaper single-layer alternatives.
If you're partitioning a room or serious about light control, this is worth picking up. Does exactly what it should, day in, day out. Good time to buy while stock lasts.
