Best Earthworm Castings Hands Down!

I’ve been growing for ten years so I like to think I know a little bit about what I’m doing. I’ve tried many different brands of earthworm castings, and Ridgeline’s is hands down the best of the bunch. What I like about it is that it’s moist and fresh without being sloppy wet and heavy. I’ve never gotten bugs from it, and no weeds have ever grown out of it— except the weeds I’m trying to grow in it! Anyway, buy it. It’s good stuff. Your plants will love it!

Gaia Green Organics Living Soil, 1.5 cu ft bag

This light is much more inexpensive than other grow lights and it's an LED so it doesn't use a lot of electricity. I got a second one to double my capacity for house plants and to have the light coming in from both sides. My house plants have made great improvements with these lights and the cold dark winter.
