repoting during flowering?

[smoky mcpot 05]

no all your re-potting should be done atleast 2 weeks before flowering. Root growth slows dramaticly durning flowering. But you're right about bigger pot bigger buds. Just not after inducing flowering. You'd problem stress your plant enough to produce balls, if its a nicely sized plant. Re-potting 3 gallon or 5 gallon cannabis plant is no easy task.

what i would do is find a smaller pot than the pot its in now fill the new small pot with soil take the old pot the plant is in and make a few holes in the bottom more open place it on top of the new pot and lets the roots travel to the new pot underneath.

just a thought ive never done it

yes that is possible its called double potting. But the idea is to get A BIGGER POT to do that with, and once again finding someone to hold a 3 gallon or 5 gallon pot for about 10 mins while you cut out the bottom is no easy feat, nevermind doing on your own.

I have seen this happen a few times before. The roots were just flying out the bottom, but 4 weeks into flowering. First time, we just transplanted. Very carefully mind you. Luckily this was not one of the most prime plants, but a loss none the less: it grew balls 1 week later. Didnt even notice much performance change either, just one day balls showed up. We attributed it to the stress.

Next time, we cut large holes all over the pot and placed it into a 5 gallon bucket. The roots did eventually move into the 5 gallon bucket, but not nearly as much as we expected. Another time, I had the fun task of cutting the bottom of a 2.5 gallon pot (by myself and yes its possible). I simply used a little Dremel cutting wheel, and literally just cut the bottom off the pot while it was on its own weight. I then...lifted the pot into a 5 gallon bucket. This worked very well, and there were significent roots in the new bucket by the end.

However, I made one more change to this method. I had to do it again by myself (yes, youd think we'd learn to use larger pots but in general 2.5-3 gallon seems perfect and most of our plants didnt get bound.) This is an advanced method. So you do the same thing as before. Cut the bottom off the pot while its sitting there. Then get some twine, and tie it around the pot. I use about 3 knots. You want it to be strong but not so strong that you cant easily cut it. Next, you make one very long slice from the bottom of the pot, in a straight line, to the top. Stop and leave about an inch. You still want the extra support the twin cannot provide. Now, in a swift but solid movement, lift the plant and pot into the waiting larger bucket/pot while you remove the bottom. Then, cut the 3 strings and the final piece of pot you didnt cut thruogh. Then, gently, open up the pot a little and slowly slide it out from around the plant. If you do it right, nothing will stick (dont water beforehand obviously) to the pot and you will be able to remove the entire old plastic pot with no stress and no root damage.

This...was the best method. The entire new bucket was filled with roots when we were done and the plant really took off after seeming very slow and stunted. About 4 weeks into flowering again.

That said, after recently observing a few more operations, I am sold on either shallow planter boxes or long, very thin and deep pots. I do not think you really need super wide and super long, just one or the other. Also if you do not water all the way through to the bottom, you will encourage roots to grow out rather then getting bound.
