Stimulators and aditives

What is an additive or a stimulator?

The additives or the stimulators are complementary products in addition to basic fertilisers that will allow to optimise the plant metabolism of each stage (rooting, growth, bloom). They permit to increase the yield and the qulity of the harvests by reducing the stress impact and by accelerating the plant metabolism.

Thanks to these complementary products, you can increase your harvest weight by 10 to 25%. Many brands propose addititives and stimulators: Aptus, Advanced Nutrients, Hy-Pro, Biobizz, Canna, House & Garden, Hesi, No Mercy, Supply, ...

You will also find out in this category about organic enriching agents such as the GuanoKalong, earthworm humus, marine algae, etc that we can directly mix into soil. All these products are 100% organic and are intended to improve the soil quality, and to be more precise, the quality of your culture.

Other products such as Co2 pastilles or the Co2 generators called Co2 Boost Generator are available. These products are used to make your plants recover in case of stopping its development that can be provoked by high temperatures or a room that is not well-ventilated.

The team is entirely at your disposal by email at, through comments, telephone at the 0034/972.55.68.69 or in the shop in order to turn you towards the products of your choice.
