I bet his house is done with r50 in the roof and
additional things to consider
Where you will get you water from
where you will get your power from if the circuits arent big enough
and I bet that house had so many lights in it, it glowed at night, no ac, sealed rooms because of the co2
not the same as one light under the truss, and insulation
both those things are issues, you could re sow the seams quiet easily, or if you dont care about looks just staple the seams with metal.
durability is less of an issue now, but the old ones would degrade in the uv from 1k hps bulbs
really not that big of a deal
and if you sell your home down...
no, not really.
this is just propagation, not modifying the organism.
this is more like taking a clone, or making feminized seeds.
basically its just cloning in agar with different hormones
think of it more like mushrooms rather than monsanto
