whats the cheapest way to grow?

its bad enough to pay to get papers signed and so on, and growing outside um im not sure of that seeing i have a cop on one side of me and the other grumpy old people and a billion damn squirrels around seeing i have a ton of evergreens around my place

How much money are you working with if you don't mind my asking? I can maybe get a list of shit together for you. What strains are you growing and how big do you want them to get? Do you care if it's soil or hydro?

I'd recommend growing in soil and getting a 1000w bulb & ballast from craigslist. Idk what kind of room you're working with, but I'd just built it myself, unless you can find a tent for a good price. I built a 5x5x7 room out of badass plywood & 1x4s for under $250 because I got most of my shit from craigslist. You can probably also find a portable A/C unit for less than the price of a high-output in-line fan on craigslist, but make sure it has a hose for output that you can run outside the room. It will help with temperature, circulation, AND humidity.
