David,
You just wait until the end of January or the middle of February when I
post links to red-ripe tomatoes, beautiful heads of lettuce and ripe,
juicy cucumbers that I pluck from my spare bedroom!
BTW, all the grow lights combined will draw less current than one 1500
watt space heater. Plus, when I wired them, I used 12/2 Romex (I had
spare wire laying around). Plus, they are on a 15 amp breaker.
But the space blankets are suppose to be the cat's meow. Get caught on
an open sea or lake in the middle of summer - they keep you cool. If you
are stuck on a glacier in sub-zero temps with winds blowing 35 MPH, it
keeps you warm.
They give these things away to like the top 100 finishers in the local
marathon, though one would think if you are in shape to run 26 miles,
you should be safe in heat or cold!
Mike
