10/15/20 gallon what should i go for

[ted55554]

I'm doing 4 plants per strong 750-watt LED light. I veg for 7-8 weeks before going into flowering. I'm doing top dressing and worm casting, not no-till. I have to consider they say to give two tablespoons per gallon. Is it worth going to 20 gallons or staying at 10? Will there be a drastic difference in yield for the extra nutrients I'll be using?

Why such big pots? The largest indoor growing pot I would consider is a 7 gal. Of course I have a small 3x3 space. I grow only photos,mostly in 5 gal smart pots.
More pot in most cases means more yield but if you know what your doing it doesnt play that much into it. Yield will depend on how your plant is trained and its feeding, Feeding more does not equal better yields. more space for the roots will tho. how much space do you have? seems like your gonna get some big plants with those pots. Hope you have a high roof. lol
