Potting question

I've done 6 grows(soil) before usally 3-5 plants with about 2 oz or so a plant dried. The gewd soil is kinda expensive, i grow mine to about 2 1/2 to 3 ft then start the flow. Im wondering can i put 2 plants of the sameish height in the 5 gallon buckets i use to grow more but save?

Bad im pretty shore it wont be a good idea, Im definatley no exspert as im only im on my second grow but cutting costs always pays in the ends seriously just dont risk it

Yea thats what im thinking, why change something thats been working fine you know? maybe if i upd the size of the pots it might work. Im sure people have tried it, be nice to get input from someone that has or known someone who has. either that or just might try it in in a few weeks when im starting up again

Thats it im still a novice problem is theres so much info on the net its easy to get mixed up but i would definatley advise to stick with your set up, Is the ultimate problem Money saving / Or you want to yieldmore?
