Suggestions, bucket size for space?

Hi , I just got my Canadian medical marijuana script uped from 10g a day to 60g a day. My wife also has a 10g a day script. I have a 30 by 30 ft main room and not sure about bucket size now. I'm currently using 15gal pots for my 100plants but now we have 350 plants and kinda stuck. I have four 25ftx4 ft long tables with five 1000w lights for each row. With about three feet of space between each table

That's going to be tight sqeeze in there. With 350 plants spread across 4 tables, that's 87.5 plants per table. If you drop down to 5 gal. buckets it would fit. You could fit up to 100 buckets per table. Any bigger and I don't think you can fit as many pots as you need to a table.

I dont know where your room is or how big the access is to it. if it was me i would try to do a giant soil bed with super soil. 1 1/2'-2' deep. lots of soil when it comes time to change it out at the end and replace it with new soil but your plants will do great. You could probably even get two runs in before having to change it just keep some organic nutrients off to the side so you dont kill your micro's with chemicals, just break up all your soil and maybe topdress a little more SS. Changing the soil using a wheelbarrow 2-3times a year wouldn't be too bad assuming you can physically. There is a guy named KushKing42 who ive seen use SS filled beds for multiple plants and his looks great, he would be a good person to talk to.

Hi thanks for the thoughts. Right now I'm thinking about using 3gal or a small 5gal pot. Don't want to do soil beds because of how wy room is set up and because i find buckets are much cleaner. The max buckets I've fit on these tables are 275 one gal pots or 25 fifteen gal pots. Here are a couple pics from my iPad and the plants are all 2.5x2.5x2.5ft all tied down because of hight issues. I have a couple of my smallest plants in 5gal and pushing 5.5ft hight in buckets not tied down. Always like to hear what fellow growers have to say ,thanks for the comments
