I'm running 192 like. 96 a month. 16 morthers. I've been thinkin g against everyones advice and going 9 plants per square foot in 2 l juice bottles which are exactly 4x4". That would up my plant count to 432 and that's a shitload of mother material needed for cuttings and I'm not sure I want either more mothers or bigger mothers. They're a pain in the ass as they are. Are you just growing straight kush or a hybrid. Kush is one of my faves never grew it but smoked a shitload. Also what co2 system are you running?
No CO2, other than what I exhale whilst tending to my garden. Im doing Violator Kush from Barneys farm. I have my mothers under a 4ft 4tube T5, all are bonzai. I clone using a 50 site DIY cloner I made which is virtually foolproof and takes zero maintainence, using a 2ft T5. Its amazing and Im going to build another so I can clone 100 at a time.
I too have moved to 2L bottles with a perlite/vermiculite mix at a ratio of 3:1.
I've cut holes in some ply wood to make a lid, so, the bottles fit nicely into the 42l tub a bit like a wine rack. This spaces them perfectly and allows me to take individual plants out without disturbing the other bottles. Im a little over 4 per Sq/ft.
Man, its soo sweet I could cry. LOL.
9 seems a little too much but it comes down to the strain youre growing. VK wouldnt do well with that (too much branching). Im assuming you would be defoliating at some point after the stretch????
EDIT: Why do you find mothers a bitch to handle? Mine are pretty much independent. What I did to make handling my 10 mothers easier to handle was sort out the drainage issue. I use a long garland tray with a hole that drains into a small tupaware box. This way I just feed and walk away.
