<span class="link_user">@PharmaZ</span>, thank you. I think we had multiple issues as this was our first grow. The second one went way better :D But keeping the environment in check is still an issue as our system isn't automated, yet. Handregulating the exhaust fan is pretty annoying. But I guess thats how you get to know the plants best and we will allways try to do better next time. :)
