Auto flower pot size

[Johnny5thesim]

Hi!

I’m about to start another grow in the next week, and will be growing auto flower for the first time. The strain is Zkittlez auto by fast buds.

I used 5 gallon smart pots for my last photoperiod grow in promix HP. This worked beautifully.

I am thinking of going with 3 gallon air pots this time. Does anyone know if 3 gallon is sufficient for this? These plants are expected to be around 18”-24” tall. 5 gallon was more then enough for a 120 day grow on much larger plants. I’d like to not have to saturate so much medium, if I can help it!

I just got 3oz off an 11" tall lowryder2 in a 3 gallon pot..not an airpot,though..
I've always used 3 gallon for my outdoor grows,got between 5-6 oz off 3 to 3.5 foot plants each.
A little easier to move around than 5's.
I think 3 gallon would be plenty big, airpots=even better.

Excellent! 3 gallon it shall be. I’m really excited at watering with less quantity. Handling 4-5 5 gallons is daunting. I appreciate the response!

Would you happen to know if peat is ok for air pots? I assume it would be.

I really don't know that answer- I just use Black Magic potting soil
Someone else may chime in with an answer for you.
