Lowryder, Lowsnow o_0 funky! need advise

Hi everyone,
i am a newcomer here and hav so far found this site really useful.
Basically i have bought 10 lowryder - lowsnow seeds from Soulseeds UK - Home which are a 100% autoflowering. they dnt actually say what they corssed with the lowryder.
these look gorgeous, loads of crystals so i thought id go with this for my first grow.

Will b using envirolites, on ebay you can get the 200W complete kit for £56
the seeds at £22.50
will be in a smallish closet in my room, foil etc on walls.
growing in soil

from here onwards i am not 100%

my questions:
these envirolites, will one 200w red spectrum light cover enough area for 4 of these lowsnows at a time?
as they are autoflowering you keep them in near 24/7 light?
what sort of soil should i be using in my pots?
what fertiliser to use, when to use and what methods.

advice and criticism greatly apreciated.
Cheers in advance!
Dan

well, as far as lowryder goes, I know absolutly nothing, but in regards to the foil on the walls statement, I am going to say DONT DO IT. It generates hot spots, and isnt really a very good reflector anyways. paint the walls of you grow room a flat white, and if you can get ahold of some mylar (can be found in some gift wrap, the type called polywrap) go with that. also, dont use mirrors, ,because these eat light.

any multi purpose compost mixed with perlite, and go for ORGANIC ferts.

cheers, do you think a single 200W envirolite would be ok for 4 lowsnows?
