Shaggy, thanx 4 the reply... DAMN 2/12 to 3 lb. clones , yeah that's the shit I'm talkin about...
I'm only workin w/ 1 1k watt hps in a 5 x 7 x 8.5 flower room... nice work keep it up.
I was thinking of trying out a big bubbler w/ overhead lighting and fimming then lsting all the shoots that pop up to somewhat replicate the vertical light by giving it a chance to penetrate into the canopy... I'm sure it won't yield as much as the vert lighting but it's worth the try. I doubled my yield on my last grow by lsting but that was soil plants from seed not doing soil indoors anymore after seeing what my hydro did in the same room.
I've been using those flexible air diffusers lately instead of air stones have you tried these..
