a little help/critique with 12x8 shed design

sweet and simple:
i have a 12x8 shed in the backyard with exposed studs so it will be easy to build barriers.
goals:
to maintain mothers and clones under the same roof where i'll be flowering
to run 600w hps lights. number depending on final design.
to utilize space as efficiently as possible.

if you have any questions, ask away. oh, please don't be shy to critique or tweak my designs. 2 heads are better than one.

pic. 1: more of a vertical approach. walkways are still being tossed up.
pic 2: false wall to light proof shed's double doors. clones and mothers in back.
pic 3: same concept as pic 2 only with walkways (in gray). dotted lines are invisible lines of separation. the upside down L shape in the top left is a cloning shelf.

sorry i messed that up. pic 1 is actually the middle picture. pic 2 on the right and pic 3 on the left.

i like the first one...and i did realize the mess up...lol...i would throw 2 600w hps in flower on either side...like the walkway idea, i would also use t5's for veg, and cloning/seedling chambers...what would be your ventilation plans? exhaust? passive intakes? either way ma man...your gunna have a hell of an OP.+rep.

on either side or both sides? i planned on keeping 2 mothers in the cloning chamber under a 2' 2 bulb t5. the clones would sit on a shelf that stacks 3 high and is 3' wide by 1' deep and i would use the top 2 shelves for clones under t5's and the bottom shelf for storage space. the top right room would be strictly veg and under two 4' 2 bulb t5's. ventilation in the flowering room i would have the 600's exhausted through a carbon filter and a blower bringing in fresh air from outside.

2 on both sides...should give you planty of coverage, and...about 4,444 lumens per sq foot...not the best. you want like is like 6,500-7,500...so a 1000w hps puts out roughly 140,000 lumens so...7,777 lumens per square foot...thats optimal...

i'd do the 2 1,000w hps one on both sides...im sure rotating the pots occasionally would increase yields on the plants that are on the perimeter

as for vegging...you know you dont need nearly as much light for that.

lol...my bad dude...the 4,444 lumens per sq. foot was for only 1 600...so 2 6's on both sides would be optimal. thats 8,888 lu. per. square foot...maybe overkill? idk...the more, the better though.

see and i read that over 10,000 lumens per sq ft is a waste of electricity and i was hoping to hit 6-8k per sq ft so ill most likely do the 2 1000 watters. veg under t5's for sure and clone maybe under t5's but more than likely under cfl's.
