QUICK QUESTION

How many autos can I put in a eight foo by two and a half foot tent with two dimgogo 1200 watt LED lights

Regarding physical space, four - six plants safely unless unusually small or large. On average, you are safe at about two square feet per plant, but there are exceptions, lots of them. Of course if you are doing a sea of green, these numbers are irrelevant. I have done three plants in a closet half your size, but two of them were known to be small strains. I have two moderate and one maybe small lady in the same 2x4 now, and it is going to get very crowded. I am going to have to make room for the smaller third plant by trimming the other two.

As far as your lights are concerned, I would need to know what the actual wattage used from the wall is. You should plan on something like 30 watts/sq ft for decent results with LEDs, and can probably benefit from more than that. So, with your space, you should have ~360 watts from the wall. If you have a lot more than that, you may need to be able to dim them.

Good luck with your setup.

350 watts from the wall. That’s what I read on reviews but don’t know for sure

Depends on pot size and what those lights do.. not dissin them.. but thats the first I've ever heard of em. Tru answer to your question.. less than u think usually.

8ft x 2.5ft tent.. so a big long yoke.. like a grow corridor lol any pics m8?

30 watts per sq ft is the usual recommendation for LEDs, but some are more efficient than others.
Your lights look like outmoded blurples with white added, and you probably will need 30 watts per sq ft.
Instead of the 600 watts for 20 sq ft, you've got only 370.
With excellent LEDs 25 watts per sq ft works, but those don't look excellent.

Grow style will influence number of plants.
In hydro, even a 2 ft x 2 ft space gives me unhappy plants for lack of elbow room.
For hydro, small autos might be fine in a 2 ft x 2 ft space, but 3 x 3 makes for happier plants.

My pots are three gallon fabric pots.. those lights pull 350 watts from the wall and 185 true watts

Your grow space is 2.5 ft x 8 ft = 20 sq ft
500 watts of the very best LEDs might work, but 370 watts of poor LED probably won't.
Only the actual space used is needed for the square footage calculation, but it looks like you'll be using the whole space.

The light is going to be your limiting factor. Unfortunately, this lights specs are sub par. Digging a little I find their PAR map

looking at this, 2x2 is the flowering footprint. So if you have 2 lights, 8 square feet of flowering plants, or 2'x4'. That's gonna be 2, maximum 3 plants in 3 gallon bags of soil. In coco, you can remove one plant from that.

Just for reference, I run 450w (wall draw) of homebuilt COBs over 16 sq feet. Good lighting and I'm marginal at the edges, would be spectacular in a 3x3. When I redo, there will be 550 to 600 watts of quantum boards covering the same area.
