Envirocycle Compost Tumbler
This unique composter has several features that are not found on many tumblers. It is one of the more cost effective compost tumbler designs. It's made in part from recycled plastics.The unit holds about 7 cubic feet of material, which is a good compromise, a reasonably large amount of material, but not so large that it can't be handled with a minimum of effort. The tumbler is a separate drum that sits on rollers on the base. The makes the act of turning or tumbling the fairly easy, without the need for cranks or other mechanical contraptions.
Because it's totally contained, there are few problems with rodents and other visitors. Turn it once a day or sow and in 4-6 weeks you can have a batch of finished compost. As with any of the enclosed composters, be sure to watch the carbon content of the pile. If you only put in green materials like grass clippings your's find it heats up too much and the pile will become a slimy smelly mess. It's simple enough to throw in some dead leaves or wood clippings to temper the pile.
Since the drum is removable, it overcomes the problem of unloading the finished compost. Normally for other composters this is done by emptying the compost into a wheelbarrow, and carting it to the place you want it. With the Envirocycle, you can push it off the base and roll it to where you want your finished compost.
Compost Tea
One of the big features advertised with the Envirocycle is the fact that it collects up to 5 gallons of "compost tea" in the base of the composter that you can take and use as a liquid fertilizer. Actually, to be specific it's not true compost tea, but a compost leachate instead. You can read more on the difference between the two at Wikipedia, where there are references to more information as well. The bottom line is that you need to be careful about where and what strength you use this leachate since it is not composed of completely composted organic matter, but has run through compost pile that is still working, and will potentially be the result of anaerobic conditions. But generally the use will improve the condition of your soil.
Where to buy the Envirocycle Compost Tumbler
This is a good deal for the price if you want a tumbler but don't want to spend a couple of hundred dollars or more to get one. You can get more features for more money, but this will serve the average gardener quite well.
You can sometimes find the Evirocycle at Amazon, however it's often out of stock there. But Yardiac usually has it in stock, and they have a low price guarantee, so you can't go wrong buying the Envirocycle Composter & Compost Tea Maker
