Help! question about pots

can you put plants into bigger pots once they are in flower, atm they are in 3 litre pots and are vegging, they are going into 11 litre pots, but i havent got enough light to cover the full area at the mo ... more light is on its way.

do they still need to be vegged once in new pots or can i flower now and change over pots in a few days, or would this effect my yields and plants growth ect

You can put them into new pots without any problems ;O)

so if i switch to 12/12 tomorrow when they go into bigger pots say next week root growth will carry on as normal

It depends on the current pot/root situation. If the roots are bound up inside your current pot, and clinging to any and every hole they can, well re potting may shock the roots a bit and growth will slow for some time after.

If the pot is just starting to be too small then re potting will generally not cause too much stress.

Just be gentile with them. If you have clay pots and you dont care about saving them, lightly break them with a hammer(just crack not smash) and the soil ball will come out easily.

na they are not in clay pots, just plastic, the roots are just starting to poke through the holes in the bottom unfortunatly
