The longer 9/6/19 review was not posted by Amazon and I’m not sure why. I’ll remove the link to Dr. Linda Chalker-Scott from Washington State University, just incase this was the issue. I will also remove the box store information regarding my DIY bins. I will not provide you with my order of preferences, and the whys, of the bins on our property since this could also have been a trigger for not publishing.
This is solely my opinion after years of composting. I'll provide you with my recommendations on closed bin versus open bin versus DIY. The tips provided are what worked for me as I do my best to work smart in order to enjoy my vegetable garden.
I'm getting ready to purchase two more Geobins. The reason - ease of use and for the fraction of the other compost bins we own: Envirocycle, Hot Frog or Good Ideas. Geobins are also more convenient than DIY bins made with 32 gallons garbage bins. We own 2 Envirocycle, 2 Good Ideas, 4 DIY, 1 Hot Frog, 1 Geobins, 2 DIY chicken wire bin and 4 DIY 32 gallons garbage bins.
Geobin vs DIY chicken wire: Geobin is the winner because of the ease of take down, set up and storage. Yes, it less expensive to use chicken wire but it's not as easy to manage set up and take down. The Geobin also provided better compost than DIY.
Tip - Geobin: Place one or two 4 foot rebar(s), minimum of 1/2 inch, within the Geobin pile to aid with aeration in the center. 1/2 is easier to find, if you have 3/4 it's much better. Place your rebar in the pile before building up for easier use. Every few weeks, when no frost, I give a couple of cranks to introduce air. I do not shred my leaves. I do not turn my pile. I don’t worry about layering. The compost I get from the Geobin is to place around my plant starts. They are full of worms and provide nutrients for our short growing season.
Geobin vs closed bin: for food scraps we utilized the close bins (Envirocycle, Good Idea and Hot Frog). We are in a city and did not wish to attract vermin. Raccoons are especially troubling and the closed bins keep them at bay. Geobin was solely for leaves, spent coffee grounds and yard waste. The quality of compost from the closed bins is decent, but it takes so much longer than Geobin. You also have to get the brown/green ratio just correct. Most times we spend a good amount of time balancing inputs for the closed tumblers or you have a wet stinky mess.
Tip Geobin two-other uses: In summer we plant potatoes or sweet potatoes. Use to keep fallen branches, in fall we place branches within beds for a mini-hugelkultur or mini-core gardening.
Tip for setting up Geobin: lay flat for a day. It’s easier to set up if you allow it to relax. DO NOT extend to the maximum. The stress could stress the plastic and have it tare. Set up the Geobin as soon as the season starts to turn. You will be surprise how quickly it will fill up with garden yard waste & grass clippings. Place a couple fallen branches on the bottom for aeration.
Happy gardening.
