Eliminating peat from an outdoor grow is good.. Alot of rodents go for the peat, not the plants, and that peat is in a really precarious place..
One of the things an old(school) guy taught me.. I said lets put it to the test, and results came up positive.. In a patch mixed with pellets and pure soil plugs in a groundhog frequented area, each and every pelleted plant was dug up and stripped of the peat alone while the soil plugs which are scary, and a pain to handle were left untouched by them.. This is a simple way to make soil plugs more convenient, which is good because RW doesn't start the best in the ground..
