The last grow, the plants would show stress at double that distance. The nutes I use contain silicon, which apparently eases the stress from led radiation. I was using the same nutes last time, but a very lax reservoir change regime. This time, I'm changing the res weekly, I think this has made the silicon much more available to the plants.
My theory will be put to the test with the addition of the side lighting as this will be 4 x 125w cfl. If the silicon does give some radiation protection I'll be pumping the equivalent of 1000w into 1m squared!
I've had a measure up and it will be an odd shape, I'm end of terrace and on a slight hill. My loft looks like the bowels of the Mary Rose! They seriously had shares in the forestry industry!
As I would cover a tent in insulation anyway, I'm thinking something along the lines of that silver covered foam type stuff (excuse the tech speak!). I've got some dexion angle frame (the stuff they build racking out of) free of charge from some skip diving. So maybe knock a frame out of that?
Defo going mars and wilma, and no more than four pots, (gotta stay under 9 plants just in case!) Of course I'll put it all on here.
I've been checking out some of @TaNg 1 pound monsters and think I may rethink the 2nd space. I've left it too late for the mile high club, but the 1 pound club........
