I am not going to stop getting high before thinking about growing weed,what fun would that be?!
I have been running a smaller setup 4 x 1k
I have seen a garden like this in a smaller room personally,it works.
Air cooled hoods will help,and if i need a ac i will get one.
I have no doubt that one could spend that much but i will spend much much less.
I will get all the fancy bells and whistles later,for now just focusing on the basics
So your saying you run 4 1000w right now, and you have no ac? Your temps would be way too high, even with air cooled hoods. 8+ lights will need at least 15000BTU of AC to maintain temps, even with air cooled hoods.
Yesterday I spent $600 on some random crap for my grow, extension chords, timers and some ducting and ducting parts. All the initial cost is pricey enough, if your gonna run 10 x 1000w in that room its gonna be easily looking at $10k plus just to get running.
Then theres the massive issue of power.. Your gonna need a professional electrician to come to your grow house and upgrade your entire electrical system. Your gonna have to have power shut down at the house to remove and upgrade your whole breaker box so it can handle the 11250w spike of the lights, and the other 10000w of AC and Fans.
The kind of grow your considering will be considered a commercial growing operation, and theres a much bigger budget for cops to find and bust commercial grow operations. Once your considered commercial you have to be so fucking squeaky clean, the wrong person hears something or says something and then next thing you know your under investigation. I would much rather get busted randomly one day by some cop cause you can fight that easily with a lawyer. Once your under investigation they are collecting evidence to procecute you in court, which fucking sucks if you get rolled cause then your fucked. Just have 2 locations with 4 1k lights on light rails.
Man seriously, if you actually do have a 4 light grow, and your wanting to run 10 lights to get 10 lbs thats like a joke.
If you actually do have a 4k grow then you could EASILY be getting 8+ Lbs with c02 after 2-3 crops to dial it in you could get 9 lbs with the right strain, just veg a little longer.
Seriously do some more research before wasting money on useless lights. Why not be more efficient, just adding lights isnt gonna add as much yield as good growing technique and the right strain.
