If it goes to an outdoor garden--I have learned that I like to plant Marigolds around all my gardens and doors! They smell nice and detour bugs! Read it in a book years ago when I planted my first vege garden. So, even if you don't have a smell problem, it will help any bug problems, it did for me! And I gro them for that reason, plus ease of growth, at least in CA! U prob. don't need them though. I had better bug free gardens with them! Good luck and please keep the gro room set up posted, will follow! thanks pr
