For over thirty years Guano has been described as a perfect (even THE perfect) fertilizer for Cannabis plants and for greenhouse plants in general. Still, the product Guano has never been seen for sale in a format that made it to a known fact in the growingbranche... The reason for it was found out by No Mercy Supply. After different laboratory analyses, performed by Den Haan B.V. ( www.denhaan.nl ), different issues became clear. No Mercy Supply has been testing for more than a year. 12 times there have been pilot-tests, in which 6 people participated independently. It was demonstrated very soon that Guano needs very much time to release it's fertilizing compounds. It became clear that the known 3-month-cycle is too fast to profit from the bat-dung in it's pure form! (Besides there is much 'Guano' for sale in which bird-dung has been added) Guano, in soil, needs about 9 to 11 months to decompose well !

Amazing... and in the same time unbelievable that this has never been investigated nor published.

It very soon became clear what had to be done. 1000 liter barrels were bought in which big pumps were placed and 75 kilo's guano per 900 liters water were mixed. With heating elements the temperature was kept around 34 degrees Celsius, while the pumps did their mixing work. After a week the pumps were turned of and after one night of deposition, the clear upper layer was pumped out of the barrels to a 'collection' barrel. Next, new water was added and the procedure was repeated. Thus after 3 weeks 3 times the solution has been 'extracted' and there was little deposition left in the barrels. The extracts were mixed and gave a mean EC of 1.4 to 1.6.

It was with this extract that, growing-technically speaking, extremely good results were obtained and the employees of No Mercy Supply were completely euphoric. From growing until almost the end of flowering this extract is truely a superior biological fertilizer for your plants. The yield as well as the taste of will profit from this very special extract.

Guano extract is a friendly (in all kinds of ways), biologically and affordable topproduct and can be added directly to the tapwater, thus very user-friendly, easily dosable, no stench, a garanteed higher yield and a better flavour of your end-product. Guano extract is truely a must for every self-respecting grower.
