Container SIZE related to Plant SIZE (HELP!)

[LilBush06]

I want to grow a 36" Sative Plant, with 4 main Branchs ( One Branch for each SQ Foot). What is a good container size for a plant like this for its whole life, i dont want to encounter rootbound. :)

start it in 1 gallon pots, when they get good roots (a few weeks after sprouting) put them in 3-5 gallon pots. I am using 2.5 gallon pots and mine are 23" and growing.

Yep that works or you could be lazy like myself and start them in 5 gallons. No transplanting or rootbound just big plants.

The max you'll need is 4 gallon pots. That'll be good enough.

Can I just ask a question?

Why do people bother transplanting anyway? It seems that the easiest way is just like Locobound said --- start in big pots to begin with.

Is there any downside to growing them in a 3-5 gallon pot from the get-go? Not that I can imagine...but maybe I am wrong.

I started my plants in smaller containers this grow and subsequently transplanted them, but next grow I am just going to start them in bigger containers and leave them there...seems more logical to me.

star and end ina 5 gallon, transplanting is a pain in the ass and can cause stress which you don't want, if you have the room and the means then start and end in 5 gallons

roots grow to the outside of the pots. alot of the space in the middle is wasted. So if u slowly increase the pot size by transplanting, you will end up having a large pot filled with roots from middle all the way to sides of pots.

Another thing to consider as well. Smaller pots during seeding and veg cycles fit better under 4' fluorescents.

Does anyone know where to purchase 4 gallon plastic square pots? Is there such a thing?

EXCELLENT ANSWER! that is exactly why you should transplant. no transplanting=smaller yeilds. if you start in a 5gal pot you will be wasting at least 60%(probably alot more) of the space that could be filled with roots if you had transplanted 3-4 times. i always started in 16oz keg cups to 5 1/2inch square pots to 1gal to 3gal to finish in 5gal. i routinely got 4-5oz per plant or more this way!! transplanting is an absolutely necessary part of soil growing imo. starting and ending in a 5gal is not in your best interest, trust me. DONE PROPERLY, TRANSPLANTING WILL NOT STRESS THE PLANT! be careful not to disturb the roots and use a product with b1 like thrive alive green and you will notice an amazing growth spurt immediately after a needed transplant. i have never seen a plant stressed or growth slowed after i transplanted. transplanting is worth it even if you think it's "a pain in the ass" good luck
