container ?

i am doing an sog in a refrigerator. will it be ok for me to put 2 plants per container? they are 3 gal rectangle 12 in x 6 in

I have found that more then one plant per container is a mistake. That is because their tender young roots can become intertwined. Untangling them is next to impossible without damaging those roots. Get a smaller container don't put them in the same container.

cool, thanks would 1 gals be ok or should i shoot for 2 gals

Which fits into your space the best. You can make either work for sog.

If your growing in a fridge couldnt you just divide it in two with some sort of divider like cardboard or something? Or if you have a two door fridge like i do you could grow one in the fridge part and one in the freezer part.

Square containers might work better for you then round.
