18 hours is good enough gives them time to rest and if ur humidity is over 50% And 95% humidity seems to much personally I don’t put domes over my plants

Your temps are perfect and 20/4 is ok. Might be a little cold though. Should still be alright. Good luck and happy growing 🌱

Put a hole at the top of your domes to allow good air exchange. Will bring the RH down to a more reasonable level If it worries you that much. Otherwise follow the great advice you already have been given

You should be fine mate. Just remember to let some fresh air get to them every so often and within 2 weeks you will find you don't need the cups anymore. Before you take them off permanently try giving them more and more time to adjust to the environment.

hi the GJ, yeah you're actually totally fine as it is, the plant creates and regulates it's own atmosphere under the dome and for the next 10 days or so you're alright at 80+F , just take off the domes when the time comes and you're golden. Hope this helps ! 🚀

Did you make some holes in the dome if not pook some hole in it so some moisture and air can come in and out other then that you could be fine little don't need a lot of light right now but warmth and good humidity with germination is good start for them good luck happy growings 🤘🏻
