Hi guys, Outdoor uk grower here. Just a quick question i've recently put behind my plants a sheet of tinfoil to reflect onto the plants but i've read from places that tinfoil creates hotspots.. can anyone give me some advice here please?
ouch, uk weather outdoor grow can be pretty hard with all that unreliable weather. hope you get lucky with the summer there this year. and stay away from tinfoil
The tinfoil is only going to create problems for you. You are already growing under the best light available. I have seen bad things happen indoors with tinfoil, never heard of using it outside. Good luck.
if your problem is heat try the green house effect , Just cover your plants with a see through plastic paper ( careful not to break any thing lolz) but this method also creates a lot of humidity and may dry ur plant but if your temps are that low it would help. not a lot of lights could compare with the sun, not even on an over cast day ( KEY WORD NOT A LOT may be some dude got some200,000 watt mh or some shit u never know)
go for it, until Myth Busters proves it to me I'll never believe this one. If you crinkle the foil and use the dull side for the reflector you'll have no problems.
