Hi guys, I have a closet thats about 2 feet wide x 4.5 feet long (so about 8-9 sq ft) and about 8ft high. I want to start a grow in this closet hopefully fitting 3-5 plants max. I plan on trying to grow feminized white widow and i want a good amount of yield (hopefully anywhere between 4-16oz). I plan on using a 600W HPS/MH combo (i thought bout getting 1000W but i wanna avoid a super high electric bill.

1. I plan on lining the walls with mylar (is that a good reflective material to use?)
2 I plan on starting my seedlings under the HPS at a very far distance of 3 or more ft away because I really dont wanna have to buy CFL lights. but i dont wanna burn my seedlings
3. Do you guys think i could fit up to 5 plants in here using 5 gallon buckets
4. Im probably going to use ocean forest soil since i keep hearing a lot about it...its just EXTREMELY expensive.
5. I want to try and veg these plants for awhile, probably 2 or more months because I want them to get about 4 or 5 feet tall. is that possible in an indoors closet?

do you guys have any suggestions for me? will a 600W HPS/MH be enough to get me that yield of 4-16oz in this closet from 3-5 plants?

most importantly what kind of light reflector would u guys recommend for a closet that size? (air cooled, wing w/o cooling,..etc)

You guys could be a great help to me. Thanks and i look forward to being a part of the community
