setting up an entire house is not small task. I would like you to literally write down every single COST associated with your grow. pots, nutes, soil, bulbs, ballasts, fans, AC units, POWER BILL!!!!!, Water bill...litererally everything you could possibly spend some money on in regards to this grow...
What about your monthly rent at this new place?
What about your monthly rent at your current location that you plan to live at? and its power bills, water, ect
What about your cell bill, insurance, gas money, car money..."the oh shit why did this have to happen now funds"
In theory you could be making money in 3 months...but lets assume that nothing goes right...and your crop dies can you survive paying both properties for another 3 months before u MIGHT get a harvest?
Whatever your budget is for setting up an entire house...triple it because u will need "wiggle" room later.
