So it was moths. And i'm killing 2 or 3 every day. Actually they are born in the tent, when lights are off, they are still in the tent, but if i switch on the general light outside the tent, they escape but i'm there and i kill them. I've got another tent working reverse from the first one, and i watch for moths and frass. I absolutly have to get rid of them even if i have to stop growing and clean every thing.
Here's a link with some more tips on controlling moths.
