Root growth during flowering

My first grow I went from 3 gallon to 5 gallon pots just before flowering and when I harvested I noticed there wasnt much root growth. Does anyone know do roots stop growing during flowering or do they continue to grow until the stretch stops? This time I am flowering in 3 gallon pots and transplant into those just before flowering. Just trying to figure out how to maximize use of my growing containers.

roots do grow during flowering, but nowhere near as much as veg...they grow more if they need to, such as if you have a problem with the roots and some die off. They really only grow them excessively if they need to, but I don't like the idea because you want to energy going into the buds during flowering not the roots.
 
So... if I veg in 1/2 gallon pots (small veg cabinet) and then transplant to huge 3 gallon pots for flowering (so the roots have all the space they may need), it's safe to say I'm wasting space because the roots will never become 6x bigger in flowering (as compared to veg)?

Could I just use a pot that's 3x bigger than the vegging pots with no risk of getting rootbound then?

well it also depends on how much/how you water... that is a huge factor in root development because if your watering all the time the roots wont be working as hard to find water, because its all there.... this is the reason why many people suggest wet/dry cycles to encourage root growth....
so during flower your roots will grow more if your pinpointing the days when they need water as apposed to when your watering schedule happens to water the plants....

when your transplanting: dont transplant because you think a bigger container is going to yeild more, transplant when the plant actually needs it, and has become root bound... the jump from 3gal to 5 gal is fine when the 3 gal pot is covered in roots.... you will know when your plant needs to be transplanted when you have to water it more frequently... you will see the bottom leaves droop more often than before and perk up immediately (within a couple of hours) when you water them.

formaldehyde: transplant atleast 1 week before flower and dont water them excessively so the roots have a chance to dig into the soil. i think the jump from 1/2 gal to 3 gal is fine if, like i said before, the plant is close to, or has become root bound.

I've never grown a plant indoors that wouldnt do as well in a 3 gallon(NSI classic 1200) than inn a 5 gal NSI classic 2000,and some seedplants have stretched to 5 foot or better.If you've trnasplanted a couple times before going in the 3 gal,that should be all thats necessary

i sometimes go from those dixie cups we all love to 3 gall grow bags. my current veg crop is in them. they are root bound i'm sure but i just break the roots up a bit, give them 2 weeks in veg and after flower the 3 gall is well rooted. root growth is definately slower in flower but it does continue. 2 months is a long time.

all i want for christmas is a bigger veg room! :)

What i did notice is that the roots will grow to emcompass whatever container they are given in veg. I mistakenly started a seedling in a 2 qt pot and the initial growth was amazing. It grew squat and wide with large leaves but the plants i had transplanted into a progression of containers soon surpassed the one i had started in the 2 qt. Even when they had reached the 2 qt stage. I guess my question is I try and allow room for the final transplant for any root growth during flower. I save the largest container I am going to use until i reach that stage. I have decided to use 2 gallon pots but because of timing am forced to veg for a while in those before i start flower. I just didnt want any pot size restrictions for additional growth to inhibit my harvest. The final root mass in the harvested ones which were in 5 gallon garbage pails seemed about the size of a 3 gallon bucket. Just wondering if anyone had any thoughts, experiences or definitive information on this.

I too have found 3 gallon to be all that's needed, unless of course your vegging a long time. I find adding some humus concentrate to my nutes at the time of transplant helps fill the container.
