Hello everyone.
This is an awesome source of top notch gardening tips, much of it based on science.
I put paver (i.e. coarse) sand on the soil surfaces of pots and it cuts down on the amount of needed water.
Maybe it will have a desired side effect of controlling fungus gnats?

Hi all,
i   use pings as a gnat killer. The best one i find is Ping x weser. as Kip said its the easest to grow and propargate.
heres a link to some of the pings i grow.I just place a few "wesers" around in my seedling house and it helps to keep them under control. I also use yellow sticky paper as well.…
