I am now a true believer in S/H. I had a couple of dendro's and catt's without roots after putting them in S/H the root on the chids are growing like crazy...Thank goodness for S/H.

Does anyone know of an online source for monoammonium phosphate in less than 50 pound bags?

I have been able to acquire all the chemicals I want to make my own nutrient solutions - potassium nitrate, calcium nitrate, magnesium nitrate, potassium dihydrogen phosphate, phosphoric acid, zinc sulfate, ferric ammonium citrate, manganese sulfate, boric acid, cupric nitrate, sodium molybdate, cobalt sulfate; except, about the last ingredient that I would like is monoammonium phosphate and the only source I have found so far is 50# bags.

I don't know if it's available in your area, but I just use Orchid Focus their Grow and Bloom formula..when they are blooming, use the bloom. When growing, the other. I've had the same bottles for about two years now and have only used about half the smaller bottles. As for hard water, we have so much mineral in my city water that it will kill a coffee pot in a few weeks...so distilled water for boiling appliances...city water for the old orchids. they do just fine. It's similar with plants as it is with fish. If you get your plats used to what is available to them, they will do fine. Too much messing around with ph and mineral's, etc..only leads to a stressed out plant. Plants are very adaptive to teir environment and water source. It's doesn't have to be complicated, just go with what you have. If you can drink, your flower's can drink it (unless they are african violets...then not so much)
