You're the one with a Ph.D I just have a P.H.D. but I save it for the ladies... anyways...

I had to get some pots for a few plants and it was either a 2gal or 3gal pot... so to save space I went with the 2gal. I had a plant go to about 3.5 feet tall and the roots didn't take up all the room in the pot! I now aim to keep it @-~ 2.5' tall. Any bigger go with a 3gal pot.

All this pot talk... it's about time :joint:

1 gallon of pot space for 1 foot of plant good rule to go by. Lowes has the 3 1/2 gallons witch is perfect I grow mine to 4 1/2 foot some times not on purpose but just giving you idea.. Also if you use hydro nutes for flowering roots wont need as much room and wont act crazy. 3 1/2 gallon is best pot for pot:joint:

Damn you got the replies, too bad it wasn't like that on my post yesterday...

Yea FDD is an Amazing guy. He's my uncle I never had... FDD in your last photo every plant looks like bud but the small guys in front and the grass, even the tall trees on the left in the background look like bud... please tell me they are...

Chitown Cubs, Sox, Bulls that's what's up, too bad the teams make me want to :spew: a lot but that's <3 :blsmoke:

On topic
From a lot of reading the root area should be around 5 Gal per plant. Yea a 5 Gal bucket doesn't get to be 5 Gal, but it doesn't have other plants roots to deal with and keeping around that 5 mark keeps the ferts more manageable as more plants take up what they need at differing amounts and water too.

Make sure the O2 for the roots match the water amount, pot size, and plants.

The pot size should be big enough to hold the plant stable when all that weight gets packed on... so like a 5" net pot with clay should work well, others go down to 3.5" Filthy Fletch did a great write up on a 6 spot DWC...

FDD, Filthy, and about 25 other people on here are my guys. girls too... They so smart... cool peoples too. :peace:
