Its done really well for me. My last harvest was great. I would agree they are expensive but i.personal didnt have.to.fork.out.the dough. And i run one small fan for a 12x12 area just for air circulation.Kind LEDs suck and i don't believe you when you say 'almost no heat at all.'
I dont know why yhey suck exactly. Sure they r made from chinese parts and there r some great American made.lights. but if money is no problem....which is rare.. my 2 kind leds are great. Best light ive ever used and puts all hps and hid to shame. I dont need someome to tell me they suck all i need is to see my awsome vegging growth and the budding is great too. It has eight timers and i swear almost no heat
