I learned most everything the hard way myself....It took me over 15 years of growing indoors before I ever grew one plant that produced over one pound of dry bud. Hell I never flushed with anything but Ph adjusted RO water before 5 years ago. I would change the water every other day. Take a reading before and after when the PPM no longer change by more then 10 PPM I thought I was done.

After the first time I flushed with Clearex I tasted a difference right a way. Then I changed to flora clean about 12 months ago. Only because I was still using GH nutrients so I thought it would work better because it's the same company. Now I just tried Final Phase and yes there is a difference again. In side-by-side taste tests the Final Phase did taste fresher is all I can say. It is a lot more expensive and I bet the clearex will work for 90% of the people who grow and it's tons better then just water. Flora Kleen I think is the cheap then Clearex. Discount Hydro sells the Final Phase for about 30 dollars a gallon and Flora Kleen for about 18.00 a gallon all USD.

I found some people who were growing almost trees about 5 years ago I learned everything I could from them they were growing 1.5 to 5 pounds per plant and were happy to teach me their technique. Mostly how they control and maintain a stress free environment and stimulant growth at the correct time.
