You can always add wing reflectors to your cool tube later to help keep the light directed downward.Hey everyone! quick question 3x3 tent should i use a cooltube only or use an xxl cooltubed hood? the hood is about as big as the tent with about 6inch open space around the edge
Any non-flammable sheet of stiff & flat (and lightweight) material painted titanium white (or appliance white) will be an excellent addition to the cooltube.
Make sure to use a paint with a flat finish to avoid hot spots on your plants below.
Could get a couple of pieces of sheet metal or sheet aluminum at a home center or find a pair of broken microwaves and use the sheet metal from those.
Or a big old computer case or two for sheet metal.
Use a $10 set of sheet metal shears (not those little tin snips with the red or green handles) to cut to length & width, add in some appropriate-sized metal hose clamps (Lowes has them in the appliance center alongside all of the washer & dryer hoses & accessories) (6" or 8", depending on the cooltube), or if you have a pop-rivet gun you can go that route, and you can make a nice DIY wing that will allow easy ducting and be lightweight compared to an XXL hood.
