4 autos enough for 3x3?

It also boils down to the strain you choose. Ive had 3 autos fill a 4x4. I've also fit 6 in the same tent. Of course photos you have much more control of the size of the plant.

For example you could probably fit 8 Fast Buds girl scout cookies in a 4x4. But with Fast Buds Gorrilla Glue, Lemon Ak47, or tangiamatic 4 may be pushing it.

I have never grown an auto-flower but when I consider how many plants to grow healthily in a tent I I calculate the square footage for each plant's canopy. Four plants in a 3' x 3' would allow an average canopy space of 18" or 1½' per plant. I personally would not do more than four if flowering in a 3' x 3' because I don't like to have my plants too crowded and want to allow for good air circulation.

What I do though is use a 3' x 3' for veg and move to a 5' x 5' for flower. In that case I am comfortable running 6 plants in my 3' x 3' for veg which is the max allowed by the government in my state. This will also allow for them to be comfortable in the 5' x 5', allowing for roughly a 20" canopy for 9 plants. Since I am not going to violate the states maximums I will have a lot of extra room in my 5' x 5'. Having some extra room is not necessarily a bad thing as it makes watering and feeding easier.

Four auto’s are fine for your setup ( light/medium) and 10 ounces is a reasonable goal if 5 gallon pots are used.

I’m a first time grower and your numbers are an eye opener for me. I wasn’t sure if having 4 autos in my 4x4 was going to be too crowded. Now I know I can get some more containers and lights 😉

Currently I have 9 plants in my 4x4x7 tent 6 plants are photos 2 are Autos. The max amount of plants that my tent can hold is 16. You are using a 3x3 so I would cut your max to 12 or maybe even 10 plants, I would have to run the numbers for your tent. I plan on doing 10 autos for my next grow, You also have to factor in the pot size you are going to use that will also put a limit to how many plants you can have in there as well. IMO.

Title says it all (almost). I’ve got a 3x3 and an LEC that I’m planning my next grow for. Would 4 autos be enough/too many to fill the tent? I’m looking for 10oz+ preferably. Anyone have recommendations for heavy producers?
