Flood and drain system??

Discussion in 'Indoor Marijuana Growing' started by 45PYE, Jun 27, 2010.

  1. Hey again peeps. Please and thank you for letting me pick your brains again........

    I've decided to go with a flood and drain system. Im going to have my plants in a soil/perlite mix ( I might part add worm castings) in pots sitting in the the flood tray.

    I'm planning to keep both the soil and the water at a ph level of around 6.5 to give myself some cushioning either way just in case.

    Does anyone know if when the tray floods and water hits the soil it will cause my ph to go haywire and if so any recommendations on what to do??:confused::confused:

    Cheers in advance
