now i want to know how long dose the light need to be on for a day

how much do i water a day? how much plant food do i give them a day thanks

You CAN, but you probably shouldn't.

Light is fine.

Autoflowering seeds can be harder than regular seeds, because you can't control when they start to flower.

Don't use Miracle Grow grow plant food. Go to home depot and get a giant thing of Premier for $10 and then get a grow / bloom set of nutrients. Is there a hydro shop around you? You can get something like Dynagrow for $20.

now, i'm not trying to be a dick by posting this, so please don't think that's why i'm doing it... but if you were to read that thread, you'll find a lot of your questions in there with very good answers and or links to very good answers..
imho, it's a great place to start out if you don't know too much already... you could also pick up a book on growing.. i like jorge cervente's marijuana grow bible, which you can pretty much pick up at any good bookstore for a few bucks and it covers all of the basics and more..

Yes, these are good for several plants.

autoflowering seeds
These automatically flower based on age, instead of photoperiod (Lights on/Lights off)

plant pots
What? I'm guessing flowerpots? of course. That's how you grow plants.

miracle grow soil
Shouldn't.

Miracle Gro All Purpose Soluble Plant Food
Really shouldn't.

Necessary

I would recommend 21ON / 3OFF every day for autos.

Depends on water retention and genetics. Treat it like a vigorous tomato plant.

the hps is good but your gunna need more than a single fan to keep the temps down. intake and exhaust fans and youll be fine. miricale gro soil will work if you know what your doing, but dont add any nutes to it bcuz it most likley already has nutes in it. just do some research thats the most important thing

Not knocking Miracle grow soil and ferts. they are good, but not so much for growing marijuana. It's sounds like your serious about this so save yourself the headache of trying to fix any problems that might arise and not being able to fix it. MG has 3 months of food they say but cannabis is a plant that needs more of some nutes than others. with mg if you try to fix one defeciency you can easily end up giving them too much of another nutrient they have plenty of causing nute burn.its nearly impossible to fix the burn since its time released.
I use the fox farm ocean forest mixed with 1/4 pearlite and use the fox farm trio for nutes. (note-not trying to imply you have to use them or anything, just saying thats what i use and am happy with)
