transplanting question

do you absolutely have to start out with a small pot and transplant into a bigger one?

only I think when you first plant the seed or root the clone.....otherwise you are merely limited by space and lighting....but if your using clones then I think its ok to plant a well rooted...ie ,you can see the roots on the side and underneath the block..... clone into a larger sized pot (same with seeds)
I hope this helps

up potting allows for a larger root mass. more roots = more uptake = more growth.

I was wondering the same thing. I have freshly sprouted plants in red plastic cups. I was wondering if it would be fine to just transplant them to some 2gallon grow bags and not transplant them again for the rest of the grow..

yeah thats what i was planning on doing too, everyone who replied +rep

You can do that and the plants will grow....but maybe not so fast

You can start in a five gallon pot and never need to transplant. That's what I always do when i grow outside. When you transplant the plant goes into shock for a week or two putting growth off for that whole period. Better to start in Original container less your doin hydro/netpots.

Then a lot of times it's more of a space issue.

thanks 4 the help, i figured i could just put it in the pot i was going to keep it in, but there are so many different grow guides on the net that all say different things, i just wanted to get different opinions, everyone has their own way of doing things, thanks all 4 the help
