Greenhouse keeps getting more expensive. $1,300 in materials coming today, should allow me to do roof, door, walls. Framing (other than one corner which is still temporarily braced) is done.
My wife [brilliant woman, doesn't get enough mention] has convinced me to extend the greenhouse (roof) another 24 feet. I think she wants me to move the tractor from in front of the RV???
Anyhow, starting to look into solar and the Aquaponics next. Have two IBC totes (275gal-ish ea) will form the main fish tank. An existing black 55 gal drum as my solids settling tank. Guy up the road stocks the half-height totes (125gal), which will become my grow beds. Still need pricing. I could support nine of those with the two big tanks as my reservoir, they are about 13.3 sq ft each - that's 120 sq ft of grow beds (think 3' wide raised garden bed, 40' long). However, that would also - after accounting for walkways - fill almost the whole greenhouse. Have some measuring to do.
Amazon has new solar panels (Renology) on Sale which deal well with part shade, and Harbor Freight has a waterfall pond pump which doesn't pull a lot of power, but moves enough water that running it off Solar with a battery back up is actually a possibility. Enough spare power, in fact, that I could add a pair of grow lights if desired. And Lowes is stocking bulk rock - NOT local limestone - in bulk as a potential grow medium flood flood and dump tanks. All that leaves is a good bit of plumbing and bulkhead fittings. and time, of course, always time.
So, its all coming together - slowly moving from pipe dream to reality. Have to do some "vertical planning" before taking next steps, to ensure I cand do a gravity fed system, rather than relying on a lift pump - that's adding a critical failure point I can ill afford, even if I find the cash for this.
