Hello again Horsemanrocks,

I have a metric shit load of scientific papers dealing mostly with C3 plants in general, some hemp related and just a couple for mj. Unforgently they where collected 3-4 years ago when I was on a horticultural kick and are stuck in my old computer. I just spoke with my oldest grandaughter who's home from college for the summer and she has agreed to try and help me retrieve them, somehow. (she's the only one in the family I can trust)

The science I referred to was from Rutgers U, where they isolated the tops and roots, then did various CO2 experiments. The short story is they found when CO2 was just introduced to the roots, leaves started to give off oxygen and some growth was noted. Very little growth but some. I don't think it is too far fetched to think roots can use co2, but does it add anything worthwhile for increased growth, I'm not sure.

And if I can retrieve some of my collected scientific papers, you'll all be sorry....
probably throw me off the porch for stinkin' the place up with academia fertilizer.
