The 12-12 From Seed Thread

Ok i wanted to do Canna coco and hesi nutes but i guess del is across the pond. It will be expensive to get those items to my door and my shop here says they cant get them at a reasonable price either. What american brands of nutes/coco would others suggest that are reasonable? I got some botanicare COCO but it looks pretty fine so i cut it about 1/3 w/ perlite for the seedling stage. When i looked at the HG nutes man they are proud of them. Dyna Gro line seems to be what i am looking at now for nutes but any other opinions on good coco?

Pretty sure Del's Scottish so you should be able to get hesi nutes easy enough

howdy guys,
been reading the thread and i totally dig it...thanks del!

I've got some seeds from a buddy's overstressed headband grow--his first real grow, and he was pretty rough with a strain that has a genetic tendency to hermie, so it hermied, oh well, free seeds!--and I'm popping 12 to go 12/12 straight away. this is an experimental run but the only lights i can dedicate to it are a 90wLED UFO and some cfls (about 400w actual rating). If I figure an 80/20 female to male rate i should get 8 or 9 gals, so the big question: what kind of performance would this light setup do for that number of plants on a 12/12 from seed? should i whittle the stock down to the 5 strongest?

organic grow with soil, in a tent, ventilation is good, humidity is in the 50-60% range, earth juice nutes with molasses.

be easy
 
They should all be female. They will just have a tendency to hermie though. A 90 watt UFO is going to have a small footprint. Just use your judgement as you go, it will answer itself for you. At a guess though, 3 plants.
 
Hi everyone - What a great thread. Decided to do my 2nd grow as 12/12 from seed. Have a tent with space for up to 4 plants so I'm growing a variety of strains under CFL's. Have well over 40k lumens so light should not be a problem as much as heat and space. Have a ceiling extractor for out take and an A/C duct feeding directly into the tents in take hole. No light leaks and RH 50-60%. Under lights temps are about 85 degrees and off about 78 degrees.

My question is there anything important in the last 700 pages or so that I should bear in mind? I read only the 1st 90 pages of this thread before deciding to go 12/12 this grow.

Right now everything is still in seedling or germination stage so plenty of time to change things if not a good set up.
 
Hey del I'm thinking of doing a 12/12 from seed in coco, hand watering, 10 plants, 9liter pots, 1000w HPS
Do u think this would be ok?
Strains are:
Bubblgum
Black domina
cotton candy
crazy miss hyde
northern lights
white widow

Do u think I could have a good run?
 
hey everyone that does 12-12! i am wondering if any of you guys make your own soil. kind of like super soil but not as strong. i am wanting to make my own organic ammended soil for my grows coming up. i will start in small cups until about 3-4 nodes than move into the "flower super soil" since it will not be vegging in the super soil i will not contain as much nitrogen. it will have a good amount of P and some K if i can find a good source of it. if you do make your own post your recipe! i am always interested. i do not know the complete recipe i only know the ingredients which are. Organic compost potting soil, bone meal 6-9-0, bat guano .5-12-.2, epsom salt, dolomite lime, azomite, and worm castings if i dont have to buy a huge ass bag.

can you top and SCROG a 12/12FS grow?

you can top and kind of scrog but the buds will probably be small since the strength of the plant is not that good. look at the led thread there is a 12/12 from seed contest and some entries that are some what mainlined and alot that are topped. if you have the time and space and everything you should just give it a try maybe it will turn out good. all the lsting might keep it in veg longer than normal

yea i just topped and put my scrog in, ill post some pics later
 
Top after the second node if your gonna top , thats the only way iv managed to get a decent topped plant from a 12/12 from seed grow , if you top any later on there not enough recovery time like mantz has said and the buds end up small n fluffy ..

I made my own soil for a 12/12 from seed grow recently. I had the same idea as you, little nitrogen since there is no veg time. I don't remember my exact recipe but I basically followed along the guidelines of supersoil, but went with about half the N based ingredients. My plants dropped all the fan leaves 4 weeks before they were ready to harvest. I would just follow the recipe man. Maybe 3/4 strength. It won't hurt them, they might just stretch a little more.
