10X10 first off you have to decide if you are going to split this area for clone/veg and for flower. I would make a chamber big enough to harbor 2-3 moms and at least 20-25 clones. So maybe a quarter to half of the 10X10.
Actually which style do you want to grow soil sea of green, hydro sea of green, scrog, so many choices?:stoned:
Cheapest way is hydro although I prefer soil. Hydro also tends to be less work as for as upkeep once started. I think sea of green with a 5X5 area under a 1000 watt puts out like 1 1/2- 2 pds (if running hydro possibly more) every 8 weeks. Then use the other half for your moms and clones.
Depends on your laws though as to how many you want to do. And which way you want to go.
Price wise, could cost you from 1000$ for a CHEAP start or go head and drop 2000-2500 and be pulling 3 pds at a time. All up to you. Hope my rambling helps a little bit.:jointsmile:
