How Many Trays to Use When Starting a Worm Farm?

worm farm with open lid

Start with only one tray, it takes a long while to fill a single tray, as the food that’s added disappears in a few days, and the level drops back down.

When the food is converted to worm castings, the level in the tray doesn’t go down anymore, and that’s when a new empty tray is stacked on top of the existing one.

  1. Love it. I use a fairly basic worm farm that I built from an old bathtub, and keep out of sight near my apartments veggie patch. I basically just keep adding to it and the worms munch it down. I didnt have much luck at all with my store bought layered kit so gave up onthat one after a few months and went the ‘whole hog’ with the bathtub

  2. I am trying to answer a question about my upgraded worm hotel please. I have three stacking tote bins. The bottom has a spigot and will be for drainage only now (i used this one bin for the past 6 months and want to upgrade to the three bins system to make harvesting easier).

    The second bin has holes in the bottom and my healthy happy worms now placed in this bin in their soil.

    Now its the third bin I want to discuss…I have put holes in the bottom and top edge of this bin and when i put it inside the second bin, it sits right on top of the soil of the second bin…there is no air gap and I assume that is good so the worms will easily migrate upward, however, as a result there is now airflow either as the third bin is directly on top of the worms in the second bin. Is this ok? I set it up tonight and have been scouring the internet to get some guidance but I andy find anyone who says whether the third bin should sit on the soil layer of the second bin or not. I don’t want to suffocate them….thank you for your help!

    1. Worm farms that use stacking trays are designed so that the trays sit at a certain level in the tray below them, which is exactly where the fill line is, which indicates when the tray is filled to the maximum level. The base of the upper tray will sit on the surface of the materials below, enabling the worms to crawl into the upper tray. That said, the trays sit on a hard stop in the tray below, which keeps all trays spaced apart at a particular height, so if any weight was put on the top tray or lid, it would not compress the contents below!
