yo jedi. i use the same method for cloning my ladies. the problem you talked about where you were having drainage hole issues can be solved by simply buying a second tray that doesnt have holes in it and putting it underneath the first one. I do this. and also, if u want good humidity, i like to ducktape the edges of the dome to the tray. this makes it airtight and allows evaporated water to build up when its under the light. my cloans root in 5 days and i get around 100% rootage
