So I'm growing outdoors but I'm extending vegging hours indoors in my bathroom. It will also be used all day on very cloudy days. I'm having 3 x 23w (6500k daylight spectrum) CFLs placed on my bathroom mirror. I've got 4 plants that will stay in these 5-inch pots until harvest. I only know 1 is female, and I will stick to the sun's light with that one. Hopefully I can get another female and destroy the rest. Anyway, I want to build a cheap reflective hood but I dont know what shape to give it. It seems the dull side of aluminum foil is best for cheap DIY. The room is naturally ventilated by 2 half-open windows and the plants are placed on top of a tall box to get them close to the lights.

...Would one just cover some flat cardboard with aluminium on top of the lights? or maybe give it some curvature?

...I heard of half-cut soda cans? how would one use them? just one on top of each light? seems small?

...what about using plain white cardboard? fire hazard?

....what about a disposable aluminum rectangular baking turned upside down?

Any ideas are very welcomed!

The 2 bigger seedlings a while back, one of these is now on flowering mode and will not be put here anymore.


This is the current setup
