My plants that are outside in pots are growing way too big for the pots and probably wont start budding for a few weeks yet - i'm feeding them with tomarite and miracle grow but i'm worried that they'll be too big to get decent buds given that they're already 8 foot or more tall and are pot bound now in 12 inch pots.

Any advice on what i should do or how much and what i should feed them with?

hey doc if the size of the plant is not a problem then i'd stick it in a 50lt and let it get big and to be honest it gonna want a bigger pot anyway. there are some tricks to growing plant big like removing inner leaves and growth points that dont get much light this will give good air flow in and around the plant and also concentrate the plants energy to the top of the branches. if hight is a problem then its not to late to do a spot of pruning. but id definitely put it in a bigger pot hop this helps

Just put them in bigger pots... much bigger pots filled with a decent fertilised potting mix.

I've bitten the bullet and repotted them - they were quite pot bound but I've been brutal

Look much better now :-) thanks guys

Brutal? Can you explain what you mean by that?

I was wondering that...

I've always thought "root bound" was a slightly over-dramatic term. It suggests that the thickness of roots in a small pot is somehow constricting or damaging the plant, which is not the case. The only thing constricting a root bound plant is the small pot.

Roots don't need to be cut, removed or in any way interfered with. Root bound plants just need to be put gently into a bigger pot and their root system will take care of itself.

Nice plants, BTW! They look like they shouldn't gain too much more height, and if they're now in big pots they should be capable of a great harvest.

Thanks for the help guys.

By pot bound (excuse the pun!) I mean that the roots are so entrenched in winding around the pot that they tend to grow inwards and not outwards into the new compost/soil.

Actually they weren't a bad as i was expecting but i did follow the advice of a friend who (although she has no experience of growing hemp) is a gardener who works for the royal horticultural society - and she advised me to pull out the roots from the pot shape and not to worry about being a bit rough and breaking a some.

I have done this as i re-potted and i think she's probably right - the plants look great - only 3 days since they were re-potted and they look much healthy and green and pert and the pots look much better size for them (50cm tubs) and i no longer need ties to stop them blowing over in the wind

thanks for the advice - I sort of knew they needed repotting but was afraid to do it as i knew it would be an upset. Really pleased it's done now.

I'm praying that they're ladies!!!!!

I will say i was a bit disappointed with the mixed indica seeds i got from the seedbank. Clearly the ones i have grown look brilliant (i think that's due to having a hot spring and a big greenhouse to start them off) - but less than 50% of them actually grew.

I'll definitely get feminized seeds next year

What your gardening friend says is true of many ornamental plants with heavy roots. Cannabis doesn't require that sort treatment and prefers gentle treatment at repotting.

About the roots guys;

Isnt good to cut away the "wall" of roots, if it has gone that far, before replanting in a bigger pot?

Offcourse it will slow the plant down a bit, but if time is not an issue, that could be good, couldnt it? To get away that thick carpet of roots that buildsup when the roots reaches through the soil and hit the potwall.

I have done root trimming alot when replanting motherplants, and will do 1-2 a year with my bonsai mother project. Found this interesting article, and have to say that it looks great!  Its a brilliant idea with small bonsai mothers. And to keep them healthy and vigorous, you cut the roots then and then.. I thought that the same idea would work with the bigger mothers i´ve had aswell, and have trimmed when replanting (in some cases because i didnt really find a bigger pot, but still wanted some fresh soil for the ladies :))

Why would it be negative, except for the few weeks of slowed growth? Isnt it good for the plant to develop new, fresh roots???
