i worked with industrial solvents for a good while, not entirely sure i will even notice the nute smell. my olfactory took a pretty hard beating even with respirators sometimes. i can only hope my biggest problem will be not having enough room but i doubt it.
my veg times will be plant dependant i guess. the ones i have going now(that are actually growing well) ill veg at least another week or so they are around 2 feet or close to 2 months. that was usually how i have done it in the past. if i had to i could cut the top out of my flower tent to get extra height and put one of my other lights underneath to take care of the lower parts if it was urgent enough. i doubt i will get to that point tho. i think 4-6 plants will fit nicely in my 4x4x6 tent.. i will adapt and overcome and so will they.
