what it do

Can some one tell me how many autoflower can a 400 watt hps and mh grow and which one will be the dest to buy.

depends on size of the autos by the time they finish, lowryders are probably gonna finish around 1 and a half or two so i could say probably six if you keep them in 1 or 2 gallon pots and grow them in a circle around the 400watt hanging in the center. you might want to prune the branches too, growing them not as bushy may be a good idea for good light penetration and air flow.

I was thinking about mi5 autoflower are Afghan kush ryder . And yes 2 gal pot i was thinking thowing in a few cfl for more light . tell me what you think what is the heat going to be like grow in my closet 3ft long 3tf wide about 7FT high going to have to have the closet door open. untill it is time for them to be in the dark. two fan in the closet up top pushing the air out and one in the room pushing air in. would that be good are what else i need to keep the heat down and i want cut any hole in my closet .

In 2 gallon pots, nine would be a good number...3 rows of 3.(3 foot by 3 foot, square, under your reflector) You could go with 4 rows of 4, but that's stretching a 400, a little thin.


Go 2 by 2, if you want denser buds.

sounds like a working setup and dont waste your time with cfls if your using a 400 watt, given they are about a foot and a half away from the light. the 3 by 3 is a great idea but it might make a couple of them be somewhat out of your range of light. if i were doing this id veg the ones towards the middle for a week or two less than others so it can let the outer plants get some more energy. and make sure the fans hitting all of them.

and if your really trying to max out your grow area in the future id recommend building shelves for pots at and make sure they stick out at about a 45 degree angle, and make sure the shelves are about 1 and a half feet higher on the wall than the previous. if you dont have problems, you could have 5 shelves(given you dont make any in the top 2 feet) on a 7 ft wall and set up 3 plants to each shelf, you have 3 walls to do this on. you might need to upgrade to a 1000watt but you have the potential to grow about 45 1 and a half foot plants that can harvest a little more than a half ounce(your energy bill wouldn't be a problem after the first harvest). lowryders would work but you cant clone them so seeds would be kind of costly. try this with some nice small sativas, or maybe try some aurora indica, its a good growing plant and if you flower it after about 3 weeks of veg it gets a good harvest.
