alright, i need some expert help here. i am currently looking at this house in an upscale neighborhood where the homes are very close together. i dont think it would be a possiblity to vent any air outside. even with scrubbers and a carbon filter, around week 9 or 10 i know there will be a smell. i am currently using a few 1000W HPS lights for flowering. i was thinking of getting a large grow tent and using CO2 with no ventilation. i really want to keep it low key, good enough so that when im trimming after harvest, somebody that walks in the front door would have no idea whats going on. the central air in the house should keep the tent below 90 degrees, i would think. are there any adequate ways to go about having efficient lighting? i know if i use HPS lights i will have to vent them, unless they are built in with an AC. but wouldnt you still have to vent that? me nor anybody ive talked to have ever used them. i was considering LEDs, but everybody told me i wouldnt have nearly the harvest ide like. i heard a few good things about bad boy T5s...im not sure about what route to take. any suggestions?
