Hi Gromie's welcome to my 8th grow, have been half hearted at doing perpetual growing in recent times. Just get a bit lazy after a grow& harvest ( as U put a lot of time, love,& energy & passion into those beautiful girls who will reciprocate the love in return in the form of beautiful sticky solid dense & plentiful buds😍 but it can take a bit out of you! I tell myself I'll take a week off & then I've got around a pound+ to trim & I end up slacking for a couple of weeks, even been guilty of murdering a few clones/ young plants by starvation & or mistreat them & slow/stunt growth. But I am tired of running out of weed & waiting ages 4 more . I smoke a lot & recoup my grow cost, nutrient, electricity & initial investment. Due to demand! (Seem people prefer to get home grown hydro due to the very high quality & great terpenes) it runs out Fast. So after much thought I've decided to get right on top of thing's with my grows this will be my 8th grow in just over 2years & the plan is to run an expanded & upgraded Hydroponic perpetual operation. Originally started in 1mx1m with 600watt hps/mh . Upgraded to 1.2m tent & mars hydro FC-E480 480watt. Fooled around a bit with perpetual using 1m tent 4 veg. 7 quite successful grows & harvest's. Average a pound per grow from 4 plants easily with the FC-E 4800. Upgraded to 1.2 X 2.4m tent for flower, using old1.2m flower tent as new veg tent & old 1mx1m veg tent will be a drying tent /extra grow space if needed.Ive also set up cloning & propergation area , storage space 4 nutrients & grow equipment & workbench/ desk to record diary/grow journal . Both tents are hooked up to a 2 into 1 splitter venting out window, flower tent uses filter both tents run 6" air extraction set ups. Clone light is a viper spectra p600 100watt fully dimmable to a couple of watts. I obviously don't need that many watts for clone area (on 25watts) but this light was cheaper than a led or T5 clone light & versatile, use in veg or flower tent. Veg runs a viper spectra XS1500 150 watt & have a 2 nd XS1500 if needed flower tent runs a mars hydro FC-E4800 480watt with top feed recirculating hydro. Waiting on another FC-E 4800 for the other side of flowering tent & will do some DWC that side. Should easily pull 2+ , training & scrogs hopefully closer to 3p
