Blue Cookies First Grow Stealth Box

So this is my first attempt. I thought I had all my bases covered, I have my Stealth-Box set up in the garage, and it's heated so the temps in my box do soar up to 30°C and I am worried I may have botched the whole thing on day one of my seedlings sprouting. My seedlings were covered in their tray, and I left them in the box with the lights off over night, thinking I had a day or two before they sprouted, so why not keep them in a dark warm place. I got up this morning and was blown away by the inch of growth, only to quickly realise that my two that had sprouted were tacoed up, bent over, and looking like they needed to cool right down. I moved them indoors to a cooler 18°C and under a different set of lights before taking the photos. I have four seedlings planted, two have popped up, the other two haven't. Can anybody inform me as to whether my two curled over babies might recover at this point? Or am I going to lose 2/4 of my girlies? I know it might be a little early to tell, but does no initial light and exposure to 28/29°C with a humidity below 30% make for a write off? What a morning. I think I'll just drink a beer and I'll let you all know what happens by next weekend. Thanks for tuning in and/or helping out.
