The advantage is that toy spend 1 time and reap the rewards. I spent 3k on my 4x4..... fully environmentally controlled.... pulled 2 - 2.5 lb grows and in 1 grow paid for itself. Yupnit costs money to start out and do thing right but it isn't more than a grow or 2 to make it back. My first grow in that 4x4 paid for itself and then some

Not trying to outright say blow money.
I'm ~$1700 into my setup at this point, excluding genetics. I intend on spending another another $400 - $600 to build the UC system, and at some point probably another $500 alone for a chiller. However, I'm looking at these initial costs as a two part benefit.
1. My current run will recoup all previous costs and possibly cover the next round of costs, including electricity and water.
2. Most components will be re-usable when I am finally able to build the room of my dreams in my shed.
Initial expenses may seem like expenditures of diminishing returns, but when done right, and the money spent on the right gear with the right plans, the ROI is equal if not more than initial cost.
