Works fast, doesn't smell, and seems not to harm creatures which eat decomposting matter. Brilliant!
I will admit that my composting needs are probably not the same as yours. In 2016 my husband bought an acre of land for me to play with. I wanted it because I felt sorry for it. One of the reasons for this was Japanese knotweed. This evil plant is almost impossible to kill, since it has become resistant to all weedkillers in my local area (West Cornwall). Local builders prepare a site by digging out and cleaning all the soil, but that is not an option for me. I have had a few years experience with knotweed, and know that it can be at least driven into dormancy by repeated mowing - but how do you mow something which is 8 feet high? And the clippings must be treated as contaminated waste by law. I have found that the best way of coping with it is to break off all the old, dead stems in February. They can easily be burned. Then as new growth begins, I pull it out every week, and put it into a 1 tonne "dumpy" bag. In four years I have not found it to be able to escape from these, but I do keep them within the area of knotweed infestation, just in case. Knotweed can grow up to a metre in a week, so a bag will fill quite quickly. It is impossible to burn unless there is somewhere safe to dry it out - an unused greenhouse is ideal. But by using these compost accelerator tablets, which I bought in July, I can compost it down much more quickly than before. An amount of knotweed which fills a dumpy bag, covered with a black rubbish bag weighed down with stones, will reduce by about a third in two weeks in the summer. I was composting the knotweed before I discovered these accelerator tablets, but it took longer. In 2017, I grew potatoes in the compost in one of the bags. They tasted slightly odd, but no knotweed shoots have been seen from that batch of compost in the 3 years since. I think flowers might have been more sensible, though. Now I can easily mow the first area of infested land I dealt with, as grass and all kinds of wildflowers have moved into what was a knotweed monoculture. I still put the clippings into a dumpy bag and treat them with this accelerator. In the fullness of time, I hope to be able to return the compost to the ground in the areas of infestation, with surveillance and continuing care.

Great
Seems to do the trick, it only takes a few days now to reduce my grass cuttings to compost, first time I used this I poured it into the middle of my overflowing compost bin and after a week it had reduced it down by a third, after 2 weeks it was down by half. It does take a little longer for plant stems and vines though as they are thicker, took around a month for my tomato and cucumber plants to properly compost down. Only real downside is mixing the tablet in water as I find it makes the compost a little too wet for a week or so afterwards.

Seems to work?
Bought this because composting had ground to a halt due to the weather. Not sure if it works or not, how do you know? It took a while before the compost began to shrink. But the weather wascwarmer and the worms came back

Excellent product
This is the first time I have used a compost accelerator and am happy to see my compost developing more quickly than expected, especially in view of the extreme weather we've been having over the summer. Thank you : )

Wahnsinn
Der Kompostbeschleuniger hat mich positiv überrascht. Anfangs war ich skeptisch, ob er wirklich funktioniert, aber er hat sich als äußerst effektiv erwiesen. Die Anwendung ist denkbar einfach - einfach die Tabs in den Kompost geben und die Mikroorganismen erledigen den Rest. Obwohl er nicht zu den günstigsten Produkten gehört, ist er jeden Cent wert. Ich konnte meinen Komposthaufen in Rekordzeit in wertvollen Humus verwandeln. Die Qualität und Effizienz dieses Bio-Kompostbeschleunigers sind beeindruckend. Auch wenn er nicht ganz billig ist, der Kompostbeschleuniger ist jeden Cent wert. Klare Kaufempfehlung
