Reflective Mylar Film + Foil Tape (50 ft)
Stage: Setup
$33
In an open space, a large share of your light misses the plants entirely and dies on a beige wall. Reflective film sends it back.
Lower and outer bud sites are the ones that suffer first without it, because those sites live almost entirely on reflected light.
2-mil diamond-pattern film diffuses rather than hot-spots, and the foil tape holds seams flat without curling.

Questions about this product
- Is this as good as a tent?
- For light, close. For odor and humidity control, no — a tent still contains air, film does not.
- Can I use kitchen foil instead?
- Not recommended. Crinkled foil creates hot spots that can scorch leaves.
