My flower tent 1.2x1.2x2m veg tent us a Dr 90 flower tent a Dr 120
Right.......look at picture below and fill your tent up in the same manner with 6.5L square pots, if i remember rightly with 6.5L square pots you can get 6 wide by 6 deep in a 1.2m x1.2m tent giving you 36 plants per tent, give em a week or 2 veg then flip em, flower them and at the end of the cycle if you have averaged more than 1/2oz per plant dry then that will leave you with about 18oz dry product per tent per cycle
18oz @£200 per oz is £3600
If you stagger your flowering tents by 4 weeks then you will be harvesting £3600 per month/£7200 every 8 weeks
