I am currently doing a 12/12 from seed and I am having some good results IMO. I will certainly make some adjustments next time (yes there will be a next time). I like it because I have so many seeds, mostly freebies, that have been adding up and I am not just really excited to grow them. This current batch is for seeds, so I did a 12/12 in smaller pots so I could fit in as many as I could to get as much selection as possible (plushxkf 2nd generation). Next batch I will be doing 7 fems and 2 regulars, strains such as WWXBB, Critical +, Super Silver, Cheese, etc. (freebie stuff) to clear out some inventory, compared to the 3 fems or 2 fems/2 reg that I normally run per batch.I'm interested to see how this grow turns out for you. Never pulled the trigger fully on 12/12 from seed but I've seen some good grows with it.
For 9 days yes I would say the plants are a little small esp to be under 400 watts. I wouldn't go adding nutes yet like stated unless its in low doeses because the soil should have enough in it right now to carry it for 2-3 weeks with just plain water. Adding some cfls would be a good idea get it closer to the seedlings hopefully you see some good growth then.
I wouldn't transplant those puppys till you have to water them like every other day. More soil, too much water. I have had plants in Solo cups for almost a month after seedling stage.Well I'm gonna add some perlite to my FFOF and transplant them in the next couple days. Ill let them sit under the cfl for a day or two after then switch back to the hps under the 400w setting. Then slowly increase it.
Interesting, I like to transplant mine early. They always seem so happy after the transplant.I wouldn't transplant those puppys till you have to water them like every other day. More soil, too much water. I have had plants in Solo cups for almost a month after seedling stage.
