Okay so i've done DWC bubbleponics in the past. had some good results and took a break from growing for a while. Now I'm within 30 days of beginning the buildout for a commercial grow and I'm really stuck on how the most cost effective & efficient way to build this. both 20x20 rooms share a wall. i'll be implementing (16) Gavita Pro Classic 1000w Double Ended Complete Fixtures and running a flip-flop so technically 16 ballasts and 32 lights (16 per room). I'm shooting for 2# per light. I have (2) 20ft. x 20ft. rooms for flowering. 16x16ft usable space because i'll need a 2ft. center aisle with 1ft perimeter around the room. I want both rooms constantly flowering so when I'm harvesting one room i'm immediately kicking new ones into flowering on the other, therefore pulling a crop every ~5 weeks. I'll grab a few 10x20 tents for cloning/veg and i have a 15x28 room that i will either use for drying or possibly keep the mother plants but it has a commercial 3-part sink in it so really its usable 15x20ft. I thought PVC pipes (16x) 12"x16ft. PVC pipes but that costs nearly $12,000 for 512ft. of 12" PVC. thats just not cost-effective. I'm familiar with building micro/closet grows from the Centrex Plastics 27ga totes, however to fill each room would be approx. 60 totes (120 total). That doesn't seem very efficient either in terms of maintenance, tubing, etc. - I'm relatively familiar with the pumps, tubing, misters, etc. I'm just concerned about the physical layout of the system i need to build. I've looked into aeroflo system but i'm not wild about what i've seen and i'd prefer a true high pressure system. Any ideas, references, pictures, etc. would be EXTREMELY helpful, as i'm really dumbfounded with how i can make this happen on the realistic budget i have left after installing both 5 ton A/C units, tons of electrical work ($24k), installing the 3 phase power, etc. etc. etc. If i can't figure this out i may be forced to growing coco until i recoup some investment, however i don't particularly want to grow coco (not saying theres anything wrong with it, i just have my heart set on high pressure aeroponics at the moment). If coco will be a significantly better, simpler route for the beginning i am open to it. Any feedback is appreciated.
