So what is a Good Sized Pot for an Autoflower

[wil2279]

Do you think 5gal would be an overkill for 150watt HPS? I'm thinkin 3gal would probably work better.

3 is probably fine

My first run of Autos were in 1.5 Imp Gallon pots, which is nearly 2 US Gallons. They are doing very well, nearly finished. My second run is being done side by side with a third run. One lot are in 2.2 Imp Gallons fabric pots, so 2.6 US Gallons. The others are in the same 1.5 Imp Gallon pots as before. These second and third runs are all the same strain, Critical Blue by Expert Seeds, germinated a week apart. So we will see what difference it makes.

View attachment 2003513View attachment 2003514These two plants are now 47 days old. These are both autoflowers(Onyx) they are from the same batch of seeds, and they were planted at the same time in the same soil. They were both grown under exactly the same conditions. The only difference is the one on the left is a 3 gal pot and the one on the right is a 5 gal pot. The shorter onyx is a pretty solid bud from the main stem up and it's only 15 inches tall. The bigger plant now has a huge main cola and several large secondary colas. (these pic's were taken well over a week ago)The 5 gal pot looks like it will have at least 20% more bud than the 3 gal pot. Anything over 5 gal is pointless for auto's because they just won't get any bigger in a 7 gal pot vs a 5 gal pot.

Hope this helps

Those are two different phenos, those plants would look the same as they do now if you planted those seeds in each others pots.

Wow, the thread that would not die... started in 2012, picked up again in 2016 and then again in 2020. Seems like every time there is a presidential election, someone revives this thread.

Here's @HighLowGrow 's comparison:
