Hey guys I know some of us out there have problems cloning in plugs.
I dealt with this issue when I started growing, but part of becoming a smarter grower I decided it would be best for the flow of my to attempt cloning straight into the same medium I grow in. Since starting this, I mastered my technique and secured my success rate to 100%(knock on wood).
Here's a little tutorial of how I get it done.
Night before prep. (under normal circumstance I prep my cups a week ahead of time to allow the coco to slightly dry, but for the purpose of demonstration I did this the night prior)
Step 1. Fill required amount of 9oz clear cups, w/ pre rinsed coco. (mine happens to be dry but it can be damp)
Step 2. I take the cups and give them a little rinse w/ 150ppm tap water to ensure good rinse.
