Ebb and flow

alright. im using a traditional ebb and flow system and i'm only wondering if having my nute solution exposed to direct hps light is going to cause any type of algae growth or anything else?


my solution is constantly moving when the pump is on and also being aerated 24/7. please and thank you for any advice.

I guess you're talking about when the plant bed is flooding. There shouldn't be a problem, you should be flooding until full, and then emptying. Your res should be covered from the direct light to keep stuff from growing in it.

HTH

your water level should not be going high enough so u see it. u need to add more medium so its about 1 inch higher than your flood level, to reduce the effects off mold bacteria ect.

thank you guys very much i just love how helpful and nice everyone s here its easy to get what you need quick.
