Hows it going Obscurus, looks like you have got a good foundation to start building off of looking at your diagram etc. Really sounds like you are leaning in a good direction with the air cooled 400 watt especially being as small as the space is. Flouros and all that jazz are great to start seeds in such but when your ready for real growth get that 400 hps going asap, it will take you threw veg just fine and kick rear in flower. Yes they will even kick some rear in veg. Youve got plenty of room to work with so long as you can get your ventilation/ temps at nice levels. Dont know a hell of a lot about soils but from what you see on here people get great results with Ocean Forest. Will try to get ya a link to a post someone had on here that really would help ya out. Hum lemme see ok dont know how to put a link in here but look 4 this in indoor growing; Mulletman:did i start my 12/12 too early. Its like on the second page when ya get in indoor growing towards the bottom. Well keep us posted.:wtf:
