I am building a 36 ft greenhouse lean to style with 300 ft of ground tubes to help modulate temps in summer and winter.. i hope it all works as as planned.

I have had cool wet spring and very little success planting medicinal seeds outdoors.  only 5 of 24 have germinated.  So I am in the market for a green house that I will build lean-to style at the back of
my pole building.  I did get about 30 bare root fruit and nut trees out and only 4 have yet to show any life.  

 I have spent the last 2 years preparing 3/4 acre lot ( that is putting in ground cover) and mulching with wood chips about 40% and putting in 3 wood buried berms (not big enough
to be called hugelkulture (sic) beds. I intend to grow a food forest medicinal focused garden for personal and commercial use.  At 75 ys I expected my kids or grand kids to benefit eventually. My area is 6b or 7 depending how
i read the charts.  Have lots of experience making traditional medications ie ointments,creams,lotions, suppositories, oils, suspensions etc.  Looking for suggestions on what to grow..Thanks
