Grow space

Also to add I can see you would need more than 3 sp6500 to adequately light that space. I would be looking to use 6 of them at a minimum. If I was using 600w hps I would be using 12 of them to give you a idea.

I would have 48 5 gal pots if that was me, that’s roughly 4 per 1.1 m2. Unless you want to veg for a long period of time I think that’s a good number to hit a decent yield in minimal time. If you want lower numbers you could try 24 7 gallon and just veg for a longer period of time maybe using a scrog net to help train a even canopy. I don’t think you could easily fill that area with less that 24 7 gallon pots as it would become uneconomical with veg time. That’s my take on it anyway, happy growing pal👍

This will give you coverage over a 9x5 area, or a 3x15 area depending on how you arrange them. Maybe 10-15 plants depending on how big you want them. You could probably fit about 40 pots if you are trying to do a sea of green technique, but this won't increase your overall yield much and it's it's lot harder to track and fix problems under this setup.
