I am having a hard time trying to choose one of this two products:

Phyton 27: http://www.amazon.com/Phyton-27-Systemic-Bactericide-Fungicide/dp/B00VKPL8FU Phyton 35: http://www.amazon.com/Phyton-Bactericide-fungicide-Substitute-Liter/dp/B00BG...

Phyton 35 is announced as the "Substitute for Phyton 27" but I feel that Phyton 27 is more tested and have a bigger user base.

Can you help to choose?

Sure! This is a fairly common question, and it comes down to what sort of plants you're trying to use this with. Some plants prefer Phyton 27, while others prefer Phyton 35. Most plants are happy with either, though, so unless you have a good reason to do otherwise, use Phyton 35.

Phyton 35 has some significant improvements that make it far better at handling plants from different parts of the world. And even some American plants have special black markings on them, or cost so much money that they're priced in Euros, or for some similar reason need the advanced care of Phyton 35. As such, I strongly recommend that you develop a taste for Phyton 35, as it will serve you better in the long run. In this era of international foods in every supermarket aisle, you cannot simply dismiss the black marks as "funny spots" and wish they'd just go away; you MUST have a fungicide which can adequately handle them.

Also keep in mind that Phyton 35 improve on previous fungicide by allowing asynchronous plant growing using eukaryotic microorganisms also known `yeast from`. -- M
