First, let me introduce myself.          

I am Giel and my venture is situated in the south of The Netherlands. After my study at the ‘Hogere Land- en Tuinbouwschool’, I further specialized in Field Crops and Plant Breeding at the Agricultural University of Wageningen.

After that, I have worked for more than 25 years in the biological agricultural sector as an informant, soilexpert, and cultivation expert. In 2004, I started a Grow Shop in Oosterhout under the name of GIEGRO. Through several contacts with homegrowing clients I noticed that there was no to little knowledge available about biological cultivation of cannabis. And besides that, dangerous chemical products were used.

With A.R.T.S., I try to build a bridge between the biological agricultural sector and the cultivation of cannabis in The Netherlands.

During the last 25 years many things have changed in the biological agricultural sector and much new knowledge was formed concerning fertilising and conserving. Unfortunatily, this has not reached the homegrowing sector yet. That’s why I want to share my knowledge with this sector and I have therefor developed a full scale of professional biological products, which can be used for all known diseases en plagues in a responsible way. Every product is named after the cause of the problem and has clear instructions for using.

Scientific research has proven that biological grown cannabis is much more healthier for the grower as well as the user than its chemical variant. To grow on a biological manner you must change your way of growing a bit. For one thing, it is important that all your plants can be reached. This is necessary for daily control on diseases and plagues. That’s why I advise you to read the following articles about the “Basic Knowledge for Succesful Biological Growing of Cannabis” in which I decribe in a simple way how to grow biological cannabis.

These articles are first published in the magazine ‘Highlife’ (numbers 1 to 3), edition 2004.

I hope the information on this site will lead you to responsible and succesful biological growing.

Sincerely yours,
