Yes those are seeds. The high heat may be stressing them out a bit. Make sure you have good air circulation too with those high humidity readings. Wouldn't want to see mold too.
How come you didn't set it up so you could recirculate the air into your house? That way you could also heat your house with your lights and have the fans running all the time to keep the smell down.
3 nights and still going at it? Lots of hash material there?
I went ahead and moved my veg plants in with my flowering plants to make better use of that room.
Re: LW's GDP, OG KUSH and AFGHOOEY
Okay this may not have been my best idea but I decided to take the plants out of my veg room and add them to my flower room. They will of course be a few weeks behind but hopefully that won't mess things up too much. I just couldn't see all that space going...
