Fans kicking up the light soil.

My new soil is very light and my fans are kicking up the finer parts and spreading it thought out the tent. Is there any sort of pebbles/rocks I can use to put a small layer on top of the soil that wont effect the grow?

You can sprinkle some diatomaceous earth on top. I believe it gets firm and crusty after a while?

at any rate, it will also serve as a natural pest control against root bugs like aphids and gnats.

A layer of clay pebbles scattered over the top of you're soil should do the job, here in the UK they only £5 for 10 litres or £15 for 50 litres, they also great for mixing in with the soil to improve drainage.

Others here have suggested something that will also discourage knats. This is a goid idea. But any inert rock or sand material should work fine. Just avoid limestone or diatomite which could disolve some and mess with your PH.
