Yes I mentioned it tonight
At one point I wanted to do three as well, but it's all about the balance; two and two keeps the power even day n night, so you're using the same AC, etc.
Also, a two week perpetual means evenly timed crops, better consistency, less mad dash to trim.
You can still seal and pump gas, you just run each room with crops two weeks apart. High ppms of co2 early in the cycle tapering down to the end, nothing changes.
Day and night cycles never change, plants really like that kind of consistency. Pulling and planting a crop every other week is easy to feed from veg, IME- three week gaps get unwieldy.
Y'all do what's best for you, let me know any way I can help!
