transplant

when should i transplant to a bigger pot? I have a few plants that are about 15 days old, they are growing great, just wondering if thats old enough to transplant or should i wait a while

how big r the pots now?

they are actually small cups right now probably 3-4 inches around and maybe 8 inches tall, but the plants are doing really well in them

Transplant them if they are root bound. If you don't know if they are or not read this:

Grow Marijuana FAQ, Cannabis cultivation - marijuana growing tips & photos

what is the best way to separate plants that were in the same pot, but now need to be transplanted?

I have 4 plants that are about a week old, they are about 3 inches tall and are just starting to develop their second pair of leaves, but i was abit hastey in planting these seeds and put then im a coke bottle in only abrout 3 inches of soil brfore really reading much about growing, i can see that the ends of the tap roots are too long for the bottoms of the conainers by a few inches are they too young to transplant at the moment? cheerrs

you are dumb. do not put seeds in the same pot.
