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:
