Didn't mean to Hijack the thread, saw his thing was answered and the info from my post might help someone else to. I'll remember people see it like this, I swear I'm not a terrorist.
And I haven't introduced any nutes to the seedling, I am waiting till the 4th week.
As with the fan, i have one up high extracting air, it does this pretty well and when it gets near time I will make a DIY carbon scrubber to put on it. If I put another fan I will need to make two right. The other fan is not that far from the other one maybe another intake closer to the bottom might help bring that hot air to the top then out.
Thanks for the help.
