I'm having the same problem. Normally my grow box runs 78-80. However, it's 20 degrees out side. I put a seed mat under the cups for a quick fix while I change some things around.
Them temps are fine,,,spring time temps fluctuate quite abit outside so your plants will be fine in early veg,, although there's a temp that will encourage more females,, but I'm not telling,lol,,jk,,,, the idea for indoor growing is to mimic outdoor growing but without the pounding that mother nature dishes out.. Storms/wind/bugs,,,
Yes you should be ok for now.
Buy a seedling mat. Heated. From Amazon. Around $20 and they last forever. Use it to germinate and to clone with. Use it on these you are doing. It speeds root development like you would not believe.
