what size pots should i use for auto diesel

i am growing auto diesel for first time plant supposed to go from seed to harvest in 60-70 days grows about 3 feet just not sure to use 3 gal pots or 5 ?

Hey buddy 3gal is enough for auto's that finish in 3months...any more is a waste of soil, space & nutes. A good rule of thumb is 1gal per month of growing. In case your unaware also, with auto's its better to plant the seed directly in the pot. Good luck.

Yes you can do 3 or 5 gallon pots. I've done 2, 3, and 5. Not much of a difference. But I use air pots. They're great. You should look into them. Prevents over watering, root bound and gives better overall results.

thanks!! i just got them in mail today from uk i am germinating them with paper towel method as i did with my out door seeds? hoping this is ok with auto's lol
