plastic tubes

That is an interesting alternative if they were left in the pile, since they would probably be difficult to pull out.  They look a lot like the tree guards I use to keep rabbits and deer from chewing on the small trees.

OG, It does look like the same product. I had planned to leave them in and harvest the mature compost up to and around the tubing as needed, then remove it easily.

Have you seen good prices of the metal tubing?

Oh, oh.  Am I supposed to cover everything with a plastic tarp?  Mowed alfalfa hay, fall leaves, bedding straw, plus 1 cup blood meal and half a bag of alfalfa feed pellets.  And lots of water on each layer.

do the pipes have holes? It will prevent the compost from going anaerobic. you'll pulled the pipes out after 24 hrs. The piles looks right , at least 12 inches from each other to prevent any dead space or anaerobic conditions. is that a breathable fabric on the back and side walls. Use a weed cloth cover on the top. Look at my pictures to see how everything is allowing air to flow into and through the pile, outside and inside to prevent an anaerobic condition.
Yes you water every layer as you are building it. this why the air flow is so important. The sources you are using is ok.

after it built, you will water everyday for one min, sometimes twice a day for very hot climates.

The pipes are rigid leach lines and the perforations are on the back sides, not shown. I have a layer of bedding straw on top, like mulch. Three (3) side have weed fabric and the front has the warped removable boards so I hope there's enough ventilation. On the morning of 4th, steam was coming out of the pipes. This evening when I got back in town, the 5th, the temps were 160*F in the center and 150* 4" in on the sides. I'm just watering with the hose as I am here 99% of the time.

So, I should remove the pipes now? I will place the bridal tulle cover over it to prevent crepe myrtle flowers from falling on it over the weeks.

Sanderson, you're doing great!!!  Remove the pipes because it getting too hot and will go anaerobic. It will settle down.  It needs the air flow. the pipes stay only 24 hrs because there not enough holes in it to allow the air to spread thru the compost pile. you need to cover the entire top of the box, no sunlight, so the microbes can do their thing. you need to find a way to make you door aerated so air is flowing from the outside in. in my pictures, the weed cloth is allowing air and water to flow through the walls and the top and thru the pipe vents. Don't let the steam fool you. it usually just a sign of two temps between the outside air and inside, like in the winter when you blow hot air out of your mouth and it meets the cold air.
ps -water every day for one minute, maybe twice a day if temps are too hot. don't let the top layer dry out, it will keep the rest of the pile moist.

Post  Dan in Ct on 7/6/2019, 11:12 am

has55 and sanderson, thank you for sharing. I haven't even started mine yet. I won't have the needed materials until the leaves begin to fall but sanderson gave me a great way to place my tubes, in two pairs and a triplet. Thank you very much. Now I don't have to get my brother to weld me anything in a circle, three straight pipes, up and out. If it helps you are basically herding microbes in an enclosed pasture, water and air regulate temperature to allow the microbes to thrive. 160 F is a critical temperature for beneficial microbes, 145 F for pathogens and weed seeds, better to stay in the 150 - 155 F. Most living things, plants and animals begin to labor just to maintain above 95 F.

Post  has55 on 7/6/2019, 12:27 pm

update, I had the holes closed again after adding two pounds of Alabama jumpers to the 2 pounds of compost worm I added earlier in the project. They have caused my holes to fill in again. I would think when they stuck their little head through the walls of the vent they would turn around, but NOOOOOOOO, they seem to continue moving through the vents causing it to fill in, maybe collapse. I'm not sure how it happening since their no camera there to catch the actual live event.
Solution: decided to use my PVC pipes since they already on hand and drill many holes into it so it is very aerated and air passes thru easily into the compost pile. I also glued and screwed to the pipe a super solar screening from Lowes to prevent those critters from figuring a way to refill the pipes. I reinserted the pipes and recovered the bioreactor. I'll let you know how it goes. The compost has dropped two feet from the 5 feet, unbelievable!!!, but it will be concentrated nutrient full of healthy microbes when matured. So a little bit of compost will go a long way.

The second Bioreactor is still open, but if it closes I will add permanent pipes to it too, but I will use a hole saw to make 1-2 inch holes in the PVC pipe and cover with the solar screen. It was a lot of drilling to make the small holes before the light bulb came on because I had not figured out about using the solar screen to prevent further closing at the time I started the multiple holes project.

So, Dan, you like my bamboo and old shoe laces set up? Wink This is my last compost pile in the 3x3x3 bin so I didn't want to put a lot of money into it, just had to purchase the pipes. I was able to use up all the stores of fall leaves, bedding straw, alfalfa hay and alfalfa pellets. Bagged composts will take their place.

Has, I don't know if I will be adding any worms when it cools. My earthworms? The pile will only be short 2' tall when it cools. Meanwhile, I have the tumbler where I used up the frozen stash of kitchen waste, plus some of the material listed above.

the worms complete the maturing of the compost. you can harvest your worms from the compost bioreactor bin to put back into your worm bin when it finishes maturing.

Razz No more worm bin. Some mammal burrowed underneath and scarfed up lots of worms. Then, the big garden roaches and black widows moved in. I'm thinking that I may use the J-Su rough compost in the 1'x50' BTE strip, then recover with wood chips. The worms can have a ball there.

I about hurt myself this evening when watering the J-Su bin wearing some slip-on bedroom slippers.  I have a layer of straw mulch on the surface to slow evaporation.  Well, I'm up next to it, watering with the hose wand, when a mouse jumps up out of the straw and runs in my direction. affraid   I jumped backwards, off a 4" ledge, losing both slippers and almost fell down.  #2 reason to end my illustrious carrier of making compost.  Razz

Note: The core is still warm at 140*F with 5" in from the sides at 122*F.

temps are good. Did you remove the pipes? Have you covered the system with weed cloth barrier? Remove the straw to prevent other mammals from coming to terrify you. You're a brave women taking on that mouse with a quick retreat.

The short pile is now down to 18". I water daily and it looks like the mouse has left the house.

yea, that was my concerns. I saw a 5-foot shredded leaves bioreactor drop 2 ft which is about the size of a standard compost pile you are turning by hand. I love not turning it, but I think you have to make it deeper. The good thing is you can see how aggressively the microbes work on it. It is fascinating.
