I went to a Hootie Blows Fish concert last night and the LED lights locked on my good looks and I can still see but I'm color blind, another reason to grow with HID.
You don't need to start one till you are ready, I found the bag works and is easy but the quality of the fresh can be so much better and I am seeing that it works but I haven't gotten a steady supply yet. Takes a while to dial in dampness and feedings and if to wet bugs are a problem especially if you don't have space for them, mine are out of the way in the corner of my garage. Some have it dialed in and can keep them inside without problems.
I think after my farm has been running for a while I'll be supplied with enough for my needs.
This is what I have and I'm happy with it.
I have the Worm factory 360 in green. I have 3 trays full and will be adding the 4th the next time I feed them.
