Thoughts on peat plugs
As mentioned earlier, I tried using peat plugs for most of the seeds germed in this grow, mostly because Cocoforcannabis recommended them, and they seem to know what they are talking about.
When I chopped the stud CBD Kush, I had a careful look at root development to see how it worked out. I was initially concerned that the synthetic wrap on the plugs might interfere with root development, so I wanted to see whether there was any sign of that problem.
Just before planting the peat plugs, I cut and removed the wrap from the bottom of the plug, so once the plug was planted, the girl developed with the sides of the plug still covered, but the bottom open.
Here is the end result:
As can be seen in the photos, there was abundant root growth through the wrap material left on the sides of the plug. I removed the wrap to check whether there was any sign of root constriction where roots grew through the mesh, and could find no hint of a problem.
I conclude that peat plugs work just fine with cannabis, and that the mesh does not interfere at all with root development. I have read criticisms here about the pH of these plugs, but in my germinations here I saw no sign of that sort of problem. Emergence from the plugs was immediate, and initial growth healthy and vigorous.
Bottom line is that peat plugs will remain in my repertoire. At this point, planting the tap rooted seed in a transplant cup rather than a peat plug is the only other approach I remain interested in.
Happy growing peeps.
