    Hi guys this is my first time growing in coco, and hydro in general.
    I am wanting to know what pot size I should use for my setup in flower. I am doing a cfl grow in about 70 coco/ 30 perlite. I have 340 watts, or 18000 lumens worth of cfls in 4 45watt and 8 20watt bulbs. I am growing one plant which has been topped, and has just begun to be tied down. Im growing in a closet that is 2 by 3 feet and about 4 feet tall but the height doesnt matter since im using cfls and need to keep the plant as short as possible. Its in a 1 and a half galon pot at the moment, but what should my final pot size be for flower, is my current pot big enough? Or could I go a bit bigger? I know that plants in coco can grow quite big in small pots, but im not sure what the best size will be for my setup.

    yep.
    you can make up for the smallish pot size by feeding multiple times during flower. you always want a bit of run off in coco too, maybe 20%.

    Cool thanks, yeah I always get runoff within half a minute of watering, about 20% I would say. Do you think it would be better to use a larger pot though, I have all different size pots, I was originally planning on using a 7 gal pot, but i was told that would be way too big for coco, i have other 3 gal pots though, do you think that would be a better size than the 1,5? Im hoping to get the largest size plant possible for my grow space and lighting.

    One plant under that lighting the 1.5 gallon should be fine for coco. I am running 630W of CMH and am in 2 gallon.

    Feed at least 2 times daily and you're good.

    You can grow large plants in 2.5 gallons of coir.

    I hope you have side lighting for those plants.

    Nope, single 6-750 gavita DE running at 825 watts in that 4x8. Average 1+ lbs per month in that perpetual. 15 years ago, I averaged a 1/4 lb+ every 2 weeks from a 400 watt setup.
