i thought of going with cfls in the past (mainly cause of their unique bloom spectrum range) Reasons i didnt, was the high cost of those bulbs and the high consuption (watt/lumen ratio ..the number of watts you have to add with CFLs to get the optimum amount of lumens plants need to give their best). Another disadvantage, is that i was always fighting with high temps in my climate, so i prefered all those ballasts to stay outside the grow space in a cool corner ( mh/hps bulbs can wire their ballasts max. 2m far for MH/ and 20m for HPS bulbs). Regarding the tent, i never regreted buying it. In the first grows without tent, i was spending hours to adjust ventilation flows/temps/humidity/smell/side reflections..etc A big headace. This shit makes growing much much easier
Are your cfl bulbs blue or warm spectrum?
