so i've started 2 seeds already and im about to put them in the system. it is a drip system using a 250W hps. but for the life of me i cannot seem to find any net pots. my question is would it be ok to put 2 plants in the system with out the pots and just sitting in the rocks?and also where can i buy a ppm meter and a goot ph meter? any help is very appriciated!
