You or someone you know eats food 😉 and makes food waste. GrubCones™ get rid of food waste. Just Google “food waste problem” and read away. The patented GrubCone™ probably won’t save the world, but you could do your part to make a dent. And if you keep chickens, feed them fresh grubs too. Please read the Product Details section carefully and all tabs. There are limitations to the successful use of a GrubCone™. We guarantee the product, not your success. Magic is not easy

Main Description

The average American family of four throws away about 1600 pounds of food scraps annually. That’s a real problem for municipal trash services. The patented GrubCone™ deals with food waste and as a by-product, produces premium livestock feed… BSFL aka grubs! The cone-shaped design allows the grubs to efficiently “Self Harvest” into a dish at the base of the unit… no touching. That’s good. The grubs can be fed to chickens at a rate of about 75% Scratch Feed (much lower cost than Layer Feed) and 25% grubs… by weight. The grubs are a super-feed… 40% protein and high in fat. They must be supplemented by scratch feed (or other carb sources) for laying hens to get the balanced nutrition required to maximize laying performance. One GrubCone™ can provide feed intensification for 6-10 chickens and decomposes 2½ to 5 lbs of food scraps per day when operating in target environmental conditions. This will lower feed costs by 75% or more… and save the world. The magic is you take food waste that was mostly carbs and would have been thrown away and convert it into high protein, high-fat livestock feed or just have 2½ to 5 lbs of food scraps disappear into thin air. That’s pretty much magic.

How It Works

A wasp with no mouth… right.

Sort of a cut-n-dry explanation… 1. Place GrubCone™ in a shaded but dry outdoor area. Like under a carport or something like that. Out of direct sunlight. If in an enclosed area, leave a window(s) open. 2. Load up the cone with organic waste. The easiest explanation is food scraps. Peelings, leftovers, spent coffee, rotted fridge food, bread etc. Rotted fruit is gold. You could use feces and carcasses (believe me)… but that’s nasty and a whole other story 😉 Not paper products. 3. Occurring right where you live (subject to Geographic Limitations tab) are boy and girl adult soldier flies which in the 10-day period of their adult life live for one reason only… to mate (while flying in the air by the way). They don’t eat or bite because they have no mouth. Really. 4. During the last days of her life, the girl Black Soldier Fly looks for an awesome place to lay her roughly 1000 eggs. Our GrubCone™ is designed to be an awesome place. She lays her eggs and before long, she and her mate die. Romeo and Juliet got nothing on a Black Soldier Fly. 5. During the time that your BSFL colony is becoming “established” nuisance flies (that do have mouths) will no doubt also find the rotten food stash. No worries, once established, the BSFL wins out and eats the houseflies. Seriously. For about 2-3 weeks it’s gross. But once established, it really does not stink and there are very few house flies. Amazingly so. You have to experience it to believe it. 6. The food waste disappears because the growing larvae are very, very hungry and there are thousands of them growing inside the cone. While the colony is being established, reduce the food scraps introduced. But once it’s established, pour in as much as the cone will hold each day. 7. Mature larvae start thinking about sex… (see item 3 above) things start getting too hot inside the GrubCone™ and they start looking for a way out. Hmmm. If they dig down to escape, they fall through holes in the floor and fall into the catchment pan. If they crawl up the walls to escape, they fall between the dual layers… and into the catchment pan. Pretty clever. 8. Feed the grubs from the pan to chickens, a pig, fish, ducks, geese etc… or sprinkle them out on the ground and let local birds eat them… or they just mature into adult mouthless Black Soldier Flies and the whole thing repeats itself. 9. But in the meantime… once the colony is established, each GrubCone™ will magically make disappear up to 5 lbs of food waste a day… actually pretty easily. 10. When the season is over, the material left in the GrubCone™ (pure organic waste and larvae castings) can be used in gardens or just sprinkled on the ground. It’s super rich and just smells like rich soil. We live outside Austin Texas, and in a season, I can put hundreds of pounds of scraps through a GrubCone™ and only empty it once winter comes. There you go. Make no mistake, there is skill and experience involved… but read all you want of scientific journals. That’s pretty much how it all goes down.

Understanding This Information More

BSFL grubs themselves are actually pretty resilient and don’t fully die unless they freeze to death. Composting material gives off quite a bit of heat and the GrubCone™ itself is dual-walled. So can you actually find live grubs in the cone for a pretty long time throughout the year? But cooler temperatures significantly slow activity, and therefore the grubs digestion of the waste, making the unit not as productive. A unit will stay fully productive as long as daytime temps get to 75°F. Temperatures for mating adults cannot drop much below 70°F at night and they are most active in like the 80°F to 95°F daytime temps. Since it’s the mating that produces the eggs and the eggs that produce the larvae… there will be a reduction in new eggs being deposited in the cone except for in much warmer times of the year… basically reducing grub production from lack of new eggs being introduced. In Haiti for instance or extreme south Florida, it’s entirely possible for the units to run fully efficiently 12 months of the year. As you go north, the yield expectations drop quickly and in fact, will be zero in inland northern states or the furthest northeast states.

Features

Key features of the GrubCone™.

The GrubCone™ is no accident. Out of a passion to serve the people of Haiti, we decided to start placing our chicken coops at schools in Canaan, outside of Port-au-Prince. A sustainable method to feed the chickens was required, en voilà… GrubCones™. Two years of development and testing culminated in a patent-pending design that is functional and interesting to look at. Shipping is normally a killer on these sorts of devices, so it was made to flat pack and be assembled as a DIY kit by the purchaser.

FAQ's

Q. Can I use my poop? A. Yes, but don’t. Q. Can I put the bin indoors? A. Yes, but if no new adult BSF can get to the bin, the cycle is interrupted.
