Quick substrate question (& kindly review the grow I'm starting)

Hi All,

I wasn't sure if I should post this here or in the 'Autoflowering' section. This will be my second proper grow ever (and the first in six years) - you'll see from my post record that I haven't logged in since 2011.

Quick background: I will be growing ten autoflowering plants in approximately 8 square feet, in a closet. The dimensions are around 2x4 feet. I'll be using two gallon pots; I'm hoping that fitting an extra plant or two in there will be worth the stunted growth from smaller pots. I'm giving it a try this way because they're autoflowering (Dinafem OG Kush Auto) seeds so the plant should stay smaller anyways.

My question: is it okay to use 80% peat moss and 20% perlite? With no vermiculite? I'll be using liquid nutrients of my own, and I hope the perlite will keep the peat's PH from going crazy.

If you guys give me the go-ahead I'll mix the soil up and germinate the seeds.

Also, one more question about lights: Is it okay to use two 250-watt CFL's in there with 6400 Kelvin bulbs for veg, then replace the bulbs with 2700 Kelvins for flowering? Is that enough light for the size of the space and number of plants?

Oh, on the off-chance anyone's grown that auto strain I'd love to hear your experience. I'm sure you guys can tell this is still new to me and I'd appreciate any advice.

Cheers,
