4x4 coco, 600w, 9 plants.. what size pots?

Doing a white rhino grow. 25C, full canna range minus boost. Canna coco, drain to waste.

What size pots? Usually I'd go for 6.6L's but now I'm thinking 10-15L.

What do you all think?

I use two gallon smart pots and can grow trees if I want.
You may just have to feed more often...
One bag of coco gets me 9 potted plants. Canna is good stuff, you should do well.

2 gallon smarties FTW!
Just had to up my watering to twice a day. I'm at week 4 of 12/12
Can easily get 2-4 zips off two gallon as long as the are some sort of root pruning pot.
 
i feel liek 2 gallon smartpots will grow a 3ft plants very well. anything bigger i size up to a 3. you can seriously grow 6 fooot trees easy in 3gal smart pots with coco.

yes 2 gallons in a 3x3 is fine. 9 three gallons in a 3x3 sounds nuts. i had a hazexskunk in a 3 gallon and it could have taken up the whole tent.
 
Cheers guys! Doing 10L's for now, but starting up some experiments with larger pots soon.. will post them up here in a couple of weeks

I found 9 x 11 ltr pots fit a 4'x4' just right,you can spread em out as they get bushy.I tried 11 plants last grow and it got a bit crowded and a couple of plants suffered.

Yea my last cpl runs in coco were using 6.5l containers or even some 5l in some cases. Yield was anywhere from 1.5-4 oz depending on plant size (2-4ft). Watered once a day...sometimes two in peak bloom. 2x 600s for lights in 8x4: good vibez

I have the same space (4x4) and wattage (600w) but only doing 6 plants... I'm thinking 3gal smartpots 100% coco? feeding once a day? should I go with 2gals?

what about blumats? think that's introducing too much complexity to a first coco run? should I just stick to handwatering? was thinking I could have a 5al bucket as a res sitting outside the tent where I could keep an eye on it, keep it topped up, and never have to go inside the tent except for pruning/training? or maybe just keep the res inside the tent, it and all smartpots over a kiddy pool to prevent disaster?

Like everyone has already stated, 2 gallon smart pots are the perfect size for 600w. I only go to 3gal smart pot for low yielders under the 600w.
