some may think im odd using d&d cups but they work wonders i poke few holes in bottom and the cup lets air in and makes good enviroment for the seedlings,just dont plant the cup in the dirt big NONO...they are biodegradeable<misspelled>but still dont do it...most of all my seedlings are planted in these cups did a few cuttings as well and between the party cups and d/d cups the d/d cups worked much better just some fyi for you guys
