Adding 2nd tent for Autos as a perpetual grow

[rydin4life]

I'm replacing four Mars hydro 300s with autocobs in my 4x4 tent so I'm considering getting a 2x4 or a 20"x32" tent and running some auto's in there for extra yield throughout the year whIle my photo plants are doing their thing. I can just reuse the Mars lights and I have a spare 4" fan around..just need a tent and a carbon filter.

Any thoughts from anyone running two tents in this manner or any reason not to do it?

I run 3... it works well for me. If I added anything more the heat would be to much. Plus the electric costs can become unmanageable if you are just growing for personal consumption.

ditto.... all those electrons get very very pricey.

Makes sense..I figure I'll save some watts going from four Mars at 132w each to four autocobs at 55w each, so if I reuse two of the mars lights, I'm still down 44 watts...add a fan and I'm still about the same so I figure why not.

now do I go 20x32 or 24x48...
