Ron,

If I recall, previous reports had indicated that Mike's growth claims

had not been replicated in the real world.  There was also concern about

lots of genetic deformities in subsequent generations.  Does anybody

have any more recent experience?

What I was thinking of was a recent ( 2 weeks ago ) press blurb he released

about a new hybrid. I too am slightly skeptical , that is why I said I have

not tried these Hybrids. Plus I think his breeding pairs are just way to

expensive. I will stick to my Aurea X Nile cross :~)

Hello Adriana,

I've been reading your post discussing cooling your greenhouses.  I spent 

some time in the midwest where it's also hot and humid.  There the most 

efficient way to cool and heat is with a heat pump system.  Plastic hose is 

buried deep in the yard where the earth maintains a constant 55 deg F or so.  

A fluid is pumped through the underground hoses and the fluid comes out cold. 

In the winter when it's 30 deg F outside the system only has to heat the 

fluid from the ground temperature of 55 to 75 instead of from 30 to 75.  You 

can also easily see the advantage in the summer.

I've seen simple setups where the plastic lines were instead laided into a 

deep pond and one where the lines were coiled and dropped into a cold water 

well.  Both types worked well.  How big and cold is your well?  Is it stream 

fed?  If it is stream fed or comes from a very big source then you could save 

on all the hose and just pump the cold water up, run it through a bank of 

clean car type radiators (with fans behind them), then through the bottom of 

your grow beds trying to extract the remaining coolness out of the water and 

finally back into the well.  The reference to a car type radiator is only for 

the style of cooling fins you'd want to use, ones with lots of surface area 

to extract the cold.  I wouldn't recommend anyone drink anything coming out 

of a real auto radiator.

Some where I have a program that could help calculate the amount of plastic 

pipe or volume of water needed to achieve a desired output.  Holler if you 

need anything.

Joel
