right on went to the hydro store today and got an ebb and flow tray/pump with the 6x6x6 cubes... my light is a 250 hps have you ever used one? Guy at the hydro shop said my yield would really kinda blow with a 250. anyways crystals comin in everywhere and the buds are growing together still not big around but not bad. Piece and remember.... water drowns, fire burns, we cant fly but we can always get high
