You should seperate them as soon as you can, taking as big of a dirt ball as you can with them. The idea is not to mess up the roots.

I grow in these $4 Walmart tubs that are 19 gallons. I'd just divy them up into 3 or 4 groups and let them grow. About half the plants will be males and the tubs can easily grow 3 plants (6 gallons of soil per plant+). Males tend to be taller with longer internode spaces. Keep a close eye on your taller plants. Cull the males as you spot them, unless you want seeds. Here's how to identify your males eariler and also have clones of your females.

When I top my seedlings (6 to 9 inches, depending on the plant), I take about 2 to 3 inches of stem, snip off the leaves that are bigger than an inch and stick the tops under a 12/12 light in a foil covered jar of water. I use a pencil to poke holes in the foil covering the top and stick the cuttings through them. These will show sex before your plants will, so number them and your plants. A Sharpie works fine on foil and I use "craft" (popcicle) sticks next to the plants. As soon as the females "show", I stick them back under 24/7. Most of the clones will take root (change the water every few days), but they may be rather slow since you have "confused" them by changing the lights. The male clones and their parent plant are gotten rid of as soon as they show.

I have a 2 x 5 feet, 12/12 lighting, closet with a shelf where the clones sit, with 3 tubs currently in use. And I have a small Chest of drawers that is my 24/7 area where the clones revert to vegging, then are planted when they have rooted, and the seedlings grow until they are ready for 12/12. Nice thing is that, if you have a real "keeper", you have a mom in veg, ready for you to make more clones! Read up on cloning and revegging. Good luck- Granny:hippy:
Storm Crow Reviewed by Storm Crow on . plants too close together i sprouted 15 random bag seeds, but some them are not even 6 inches apart. should i leave it like that for now or should i pluck the weakest looking ones out of the ground. Rating: 5
