I run what I believe to be a fairly affective medium size indoor set-up averaging 10 lbs every 85 days.

Using my numbers and a little multiplication will show what is necessary for a grow the size you are asking about.


With just 200 ft2 of canopy I average 1 lb for every 20 ft2 of canopy. To achieve your 20-30 range you'd need 400-600 ft2 of canopy.

After figuring in all of my costs (clones, nutes, electricity, trimmers fees, rent, ....etc) my monthly operating costs are around $3500 a month and generally come to a bit over $10k per cycle. Other than the rent all of the other costs would go up with a larger grow. Best guess is that a huge grow, like you are describing, would cost at least $5k-$7k a month in operating costs.

My 6000w plus fans and all the extras cost me a bit over $7k in equipment. Yours would require at least twice the investment and more likely a bit more as a huge set-up like that is going to take some industrial sized HVAC systems to keep it cool. Best guess would be $20k for initial set-up.

Another factor is the reality is that huge gardens usually run slightly less efficient than smaller grows. Its probably a lot to do with the care and attention for each plant but just because you can do a gram per watt on a small grow doesn't mean that will translate into the bigger wattages.


In conclusion my best guess is that to do a 20-30 pounder would take:

400-600 ft2 of canopy (add another 400-500 ft2 if your going to do your own cloning)

likely $20k+ initial set-up costs

Monthly operating costs of $5k - $7k




With a $10k nest egg you might be better to start with a smaller one or two light scene until you get some more experience and capital.
