I have been using rabbit tea as my only veg nute in Happy Frog or Ocean Forest with great success. My wife raises rabbits so its easy to get. I highly recommend it. Never burns and plants love it.
I like Timber Grow Lights. Already put together ready to mount on a frame of your design/choice. Takes all the guess work and extra expense out of it. Buy their's. You won't be sorry.
@Airwalker16 - that is untrue. These are purchased directly from Ledil along with the other Ledil accessories we use and sell.
Don't have any reflectors from Jerry - never used them.
Please check your facts more closely.

So whats the sf light coverage recommended for 4 cree 3590's ? 200w at 50%. What happens if I run them at say 80%? More heat? How much more light area? Probably won't run them too long anyway as new tech lighting comes along maybe CMH?? I'll want that. Know hat I mean?? So running LEDs hard...
what about heat sinks? I live in Eastern Oregon at 5000' with a hoop house. Could use use some warmth options. no electric available cold is coming fast

What are you running for lights now?? I'm still contemplating my 18"x27" area. Thinking 6ea vero 18's on 1 dimmable driver. Veg and flower both so 4000k. Sound reasonable? Or 2ea 3590's ??
I'm using a 300w power supply out of a desktop computer. Run as many 12 fans as I want. I get them and the fans and the heatsinks for free from a computer repair place. Units are going to the dump. May even use the case horizontally to be the light case. I have found that I can get a variable...
I like your thoughts on the more even intensity and light spread. I've drawn some diagrams of various light layouts and the 6 vero 18s in a rectangle look awfully good. How big is your grow area? I'm wanting to do this once for this area and do it right. I like the idea of 2 cobs for simplicity...
