Does pot size matter

if i veg for about 40 days from seed and go into flowering would i be able to finish the full grow in a one gallon pot. My plan was to uproot the whole plant get as much soil out as possibly without hurting roots and adding some Dr. Earth organic soil then switching to 12/12. would that suffice or should i transplant into a 2-3 gallon pot??.

unless your doing an experiment, 1 gal will not give you a yeild that will last 2 weeks.
To me anything under 3 gal and you'll not get 2 zips per lady

Transplant to a 3 or 5 gal pot when the 1 gal is rooted to the sides and bottom of the pot. Do not try to remove the existing soil from the soil ball. You will do more damage than good. When the one gallon is ready to transplant take the whole root ball and transplant into a 3 or 5 gal pot then let the plant root for a couple of weeks or more before switching to flowering cycle.

will it work...depends on what you call "work"...if you veg for that long its going to be root bound in a one gallon pot.this is going to stunt your plant and drop your yield.if left in that pot i woulnd not veg it for more then 20 days.but best bet would be to transplant into something at least 3 gallons or more

the only part that was correct about this was to transplant before entering flower....why would you just leave the root ball intact.its best to break the root ball up...if not the roots are going to stay root bound and not spread out into the new soil..making the transplant useless.when i transplant i cut a X into the bottom of the root ball and break up the soil.this does not hurt the plant...it helps it...look into root pruning

There is no reason to tear up the root ball if it is not rootbound. Unless the roots are really dense and net-veined and encircling the soil ball there is no reason to disturb them. If they are starting to become a thick dense mat scoring is beneficial to the transplant.

If you are observant and transplant when the plant is ready it will not become rootbound.

i use 5 gallon pots and wish i had space for 7 gallon pots.

size matters
I found that with 5 compared to a 3 gallon pot, the 5 was a waste of 2 gallons of soil from my veg time and all. If they had been in the pot any more than 3 months, I would go with 5,anything under Id use 3.
just from my exp,

take it easy all.

I use 3.5gallon except when veg for 3+ months then I will transplant to the 5+ - I find 3.5 to be a good # with my enviroment I never have rootbound but it all depends on what soil you use, strain, and nutes that you use.....some people have better roots than others.
 
thank u all for the replies. ill prolly be looking for 3 gallon pots this week so i can give my ladies a new home and flip em.

I run 4x4's till they are bound, into one gallons until bound, then 2's then 7's and it has produced some bushy trees with 1.5" thick stalks.

you didnt tell what sorta light you use.

but if its hps, then yes 3-5 gallons last size. (could probably half that for cfls and t5 in flowering)

40 days veg, could probably get away with 3 gallon.

im using a 180w blackstar and i just transplanted into 3 gal pots i have one confirmed female and the other is still unknown. i was gonna flip the lights in bout 2 days, is that enough time for them to adjust to the new home or should i give them some more time??

if they respond nicely to the transplant, then yes, though more veg time would be good too.

since mj doesnt really grow much roots in flowering. (ive sometimes just added an inch of soil just before flowering and been fine on some plants, others needed another inch.

depends on how much space you´ve got left and the penetrationpower of that blackstar how much longer id veg, if at all.
 
I would give it at least a week, or 2 or 3 waterings/feedings until you change.. Might sound dumb but I feel that there most fragile the first week after getting transplanted. But all plants are different and some thrive better than others in new environments

^^^ Agreed ^^^ Ive never done a side by side test with 2 different pot sizes but I would have to agree with Wiseguy! Big difference..
I have done a side by side with 5 gallon and 3 gallon pots,,vegged both for 1 month,both same strain,,fair enough they werent clones,but both same batch of femmed skunk seed,,and there wieght was the same,size the 5 gallon was less than an inch taller,, so I drew the conclusion that unless there is a longer vegg time,the 5 gallon is a waste of soil.

My grow bible also states that any longer than 3 months go bigger than 3 gallon,,but 5 gallon for 3 months is a waste of 2 gallons of soil,,fair enough a larger pot will make salt build(nute burn and lockout,pH change) less likly but for time scale and size I grow too 5 gallons is a waste of soil....

Thats my exp.... Im not saying right and wrong,,so dnt take it wrong,,,take it easy
