I agree, it will work OK...but if you want it to be puuuuurrrrrrfect..go with clean water everytime. It does'nt make sense to have the best lights, nutes, strains and techniques and then feed them tap water that most times contain high levels of chlorine, excess minerals harmful to plants and fluoride, etc. Invest the few hundred bucks in a good R.O. water filter it is literally one of the best possible things you can buy for your grow.

PS - your plants look great! :thumbsup:
FreeDaHerb Reviewed by FreeDaHerb on . pH in hydroponics (auto-drip coco)??? I recently got my plants a hydroponic system, but keeping the pH level in it at 5.5 - 6.0 is really difficult. The water with nutrients in it is at about 6.8, and then we add "GHE pH down" which lowers it to 5.5 - 6.0. But after a few hours its back to 6.5. Could the problem be that the plants are eating up the nutrients and leaving the pH closer to clean water pH? :P And should i just leave the pH at 6.5 ? Oh btw, plants are just about 10cm tall, growing a bit slow compared to what i'm Rating: 5
