I like to wait on the plugs until there are multiple roots extending out of the material, then into a bed of soil in a solo cup. There I wait to see roots extending out from the holes I’ve prepunched into the bottom and lower sides of those cups. I’ve gone further and hot glued small cuts of pvc conduit (about 1/2”) into the bottom of a second solo cup, where I then place said cup containing the new seedling. The second cup allows excess moisture to drain from the seedling cup and also allows air to those growing roots.
