My old CFL bulb (150w) with reflector in a cardboard box Is not a good setup, way too much heat.
What should I use to keep on vegetateling my 3 survival clones? A supermarket LED light? How big? Thanks
my advice is Sanlight Flex lights, 2x 10w lights made my first 2 weeks a damn breeze and leafs now grow massive. I really can't recommend enough, cheap, eu made, no heat and you really can't burn small ones with em. after girls are 20cm you can switch to proper lights.
