need a little guidance from someone who's already got the awnser

Mother on ground, build a few shelves on the walls about 3 feet up. Only make them wide enough to hold your clone trays.

another thing you can do is buy/steal/find some of those milk crates or other wire crate. basicly you can stack a few of those an put plants inside of them (like 9 clones each) and put mothers on top. mother get main light an clones get ambiant light. in my veg tent the lower crates still get alot of light but im havent put clones in there yet. the crates are about 12 inches sq. also shelves work well like the other guy said. it really comes down to how long to plant to veg for cuz you cant really get alot of plants really big doing this but if i were doing the crates i could prolly get 27 clones about 8 inches tall before having to move them. 27 is assuming a 1-2 foot squar space

see all this is good stuff.. im glad i got turned on to this site. i like that idea about the crates. these are the little tidbits of info i need. i didnt think that i would be able to have that many plants in that small of an area. thats about the size of the area i will use for flowering. i just know that i will have to deal with this heat when it comes time for the hps light to be on for the whole day. ive been trying to figure out a way to make a lightproof area and still be able to ventilate. i think i am going to be on the lookout for some heavy black cloth and velcrow. i want to make a flap that i can velcrow to the sides of the wall to create a lightproof barrier. if i use dryer hose i think i can find out a way to create an exaust and intake into the "tent". each of the grow areas has a canopy and three walls. so i will just build the door somehow. any help on that would be great. cant i make a carbon filter at the same time? i think i can imagine the basic plan but need to read up on that to. thats my bigest thing right now, trying to figure out the light curtain. or whatever is smarter than that that i couldnt figure out.lol. thanks man i apreciate all the help. peace.
