Micro grow questions about temp and ventilation

I have created a micro grow fro my first home grow. I put in a fan for ventilation, which leads to a crawl space. Since installing the fan, the temp dropped from 80-85 F degrees to 70 F degrees.

I fear this is too low. Is it? Any suggestions on how to get it hotter if need be? I have pics and more info about the grow at my grow journal: Found here.

I'm including one pic here so you can see it. but i have a bunch more at that link. This is Day 8.

No I think thats fine. My grow space stays anywhere between 65 to 75 and they look great. But some strains are more sensitive.

What I learned over my first couple grows was that its a hardy plant.. keep it simple, meet basic needs and they will do great. If you have something to worry about your plants will show you signs that they aren't happy days or weeks before they get to the point of dying or becoming permanently damaged.

To be a good grower you need to learn to recognize when the plants are stressed, figure out why, and then avoid it happening again. Worrying about every little thing is stressful and pointleass.

Good Luck!

Awesome. Thanks Sir Psycho!

You could get an adjustable dc adapter. Mine can do 6/9/12/15volts and I just turn the volts down on the fans when temps get cooler. Computer shops also sell resistor cables that will slow fans down.

Thanks for the advice. When I got home yesterday, the temp had risen back up to over 80F degrees. THis morning it was right at 80F. So I guess it just needed some time to warm up. It also probably had to do with me covering the intake hole in the bottom right corner with that book.

Once i get a little screen to cover it to keep the bugs out, I am going to leave it open, which will likely change the temp.

But from what I am hearig, i am worry about this too much.

So now I need to figure out when to put them in bigger pots. I am thinking the sooner the better. Anyone have any thoughts based on tht pic i put up yesterday? I do also have a lot more pics at my grow journal. the link is in my sig.

thanks, bro
