The problems i had with the Hydroton occurred on my 4x4 ebb and flow/flood and drain table....and yes through out the grow the Hydroton will come in contact with the nutes...3-4 times a day...lol.. capeesh ...:smokin:
The exact same table and system i used to grow the plant in my avatar...in the same white pots...lol...only difference is i was using the cheep lava type grow rocks...which did not required Ph-ing....
