Failed at calibrachoa rooting, why?
I'm wondering if anyone has any tips as to why my attempt at calibrachoa (million bells) rooting failed? My setup was a bit amateur. I used a recycled rotisserie chicken container for the greenhouse (saw it on pinterest) and for the bottom heat I had a couple layer of things, a coffee/candle warmer under a pyrex casserole dish, which I thought was too warm so I put one of the microwaveable warming packs in between that and the greenhouse. That way everything was "warm" and not hot, plus the pyrex I had no concern for overheating. This was set up for at least a week and the cuttings were doing ok, then they just kind of started to slump over one by one (I had 4, 3 inch cutting with 2 or 3 leaves on the top). I used rooting hormone and the medium was half seed starter mix mixed with my regular potting soil. I did let it air out once in a while because the condensation got a bit heavy on the top. Should I have had holes on the top of the cover? I also sometimes took the cover off which seemed to perk them up a bit, it was like a constant "no were happy like this" and "now were happy like that". I didn't have them in direct sunlight, I had them on a shelf by a SW window. I sprayed them with a spritzer when I thought they may have dried out but wasn't sure how dry or wet I should've let them get. Should I have not sprayed the leaves? They have gotten dried out from the bottom heat if I left the cover off too long. I'm not sure what else I could've failed at. Anyone have suggestions? I want to give it another try, I love calibrachoa but lost two last year to aphids or root rot so I kinda want some backups or extras to add to my existing baskets.
