    Club 315w lec

    Ill never switch back to 600 watt these 315s do exactly the same and sometimes more then my 600's did ( yes one 315 is doing = or more then one 600) . half the electricity half the heat. Denser, more colors. The frost seems about the same.

    couple issues, with pics need help. PH / Fungal?

    Another thing i wanted to add, all plants have res tables, I water the table and let them sit an absorb the water. The seedlings are in the little black flower trays and i did the same with the peat pellets. Could this be as simple as root rot with PH issues ?

I thought 700ma ran them soft and produced the best results and least amount of heat, i might be reading stuff wrong, im new to this. Thanks...

    I wanted to do this same build about 18-20 - cxa2530. Im totally new to all of this and wanna do a poor mans build. Would HLG-185H-C500B run 9 cobs ?
