Auto Flower Grow Pot Size

[Jo2]

I have a 4*4 foot tent with a 7 foot ceiling and and a 600w bulb. I am going to start a new crop with auto flowers with a 90 finish time. I am not sure about the size of pot to grow them in I use Foxfarm soil in cloth pots. Any help would be greatly appreciated.

I'm not a auto guy but I've been around here for a minute and have read alot lol. What I'm hearing from most is 3 gal pots are perfect for autos.

After trying a few pot sizes, for indoor grow, 5 gal fabric pots are my preference, but 3 gal seem fine. Autos grow fast, more room for root support more flower up top. 4- 5 gal in a 4x4 would easily give you a great canopy. If you want more than 4 plants 3 gal containers would be better. As always, its grower choice. I use 2,3 and 5 gal depending on what I want in the end, or if ill be transplanting.

I use 2 gallon Geopots - easy to control plant size.

I'm currently using 5 gallon fabric pots for my autos but in my upcoming grow I plan on using 4 gallon pots instead.

A 4x4 tent with 4 x 3 gallon pots sounds just about perfect to me, I have 6 x 3 gallon pots in my 2x4 tent and it is quite full already and I'm only just about half way in the grow.

LOL aren't we helpful too many choices. 3gal you'd be safe

 

[Farmbuck]

5 gallons is what I'm using

SoOrbudgal lol at your comment. But yes I think there is a lot of choices or preferences but seems like 3 gallon pot is the most common denominator. I recently purchased Grassroots pots for living soil for my auto flowers. I went with 3 gallon.

I've grown a number of autos in a variety of pots. For this latest grow I found these 3.6 gal semi-rigid plastic pots to be a good compromise between 3 and 5 gallons, and between cloth and a more rigid plastic. That's a 2 litre pop (soda) bottle for comparison. I find the plastic holds my cages more solidly than cloth, and I've had problems in the past with my cloth bags being wet for too long and flirting with mildew issues. I punch a bunch of holes around the perimeter of the pot for enhanced drainage and to try and get O[SUB]2[/SUB] to the roots. 4 days between fertigations at average 74F and an RH of 45-50%. These plastic pots are cheap, and seem to be working well this grow. I also have a 4 x 4, and 6 will fit depending upon your canopy spread of course.

Sorry to throw another option into the mix :doubtful:

Yep i love these grows breaking the barriers

I can see why those pots would work well for cannabis plants - cuz they are tall.
