>Hello all,

>On reading through a greenhouse catalog I noticed that the shading material
they sell comes in different percentages of darkness eg. 65%, 80%, 85%, etc.
the higher percentages producing the darker shade or if you prefer less
light. This is accomplished by weaving in more black fibers to darken the
material and absorb more sunlight. My questions: what is the ideal amount of
shading for a growing giant? Is it that critical or will just any shade do?
How about simply covering with a refrigerator box and just cutting some air
holes on the side. Is a green net better than black? blue tarp? bed sheet?
or solar blanket to really reflect the heat away.

answer to my best bull vs. best cow question. Thanks.
