What size tent is good for 4 auto plants in 3 gallon pots. My max limit is 5 plants! I figured my time..make it a good one. I read 50w max per sq ft for auto’s or any plant. I want to then cut at the 3rd node for training. Probably need two lights now.Ideally you want about 60w per square foot with the ability to dim it down to 30w/sq/ft that way youre covered from seedling to flower and have a little extra to use as the LEDs slowly get dimmer over the years.
2.5' x 2.5' x 5' is probably going to be a tad small for 4 plants.
You're likely going to end up with a blivet if all 4 plants grow well.
