Welcome to Biotops, your growshop located in La Junquera - This site is reserved for a major and informed public.


In order to obtain great harvests, it is very important to give your plants high quality fertilisers such as the ones from Advanced Nutrients, Aptus, ... with the aim of promoting the growth as well as the blooming.

It exists organics fertilisers (with a slow absorption) such as the Iguana Juice Bloom, Iguana Juice Grow, Bio Vega, Bio Flores, ...  and organic-mineral fertilisers (with a quick absoption) like the Hesi complex TNT, Hesi floraison, Terra Flores and Terra Vega.

You'll find solid and liquid organic fertilisers, as well as complete and profesionnal lines, each one working with specific cannabis growing plan.

We also propose you stimulators, designed by Aptus (see the video below). They complement the fertilisers and facilitate the nutrient absorption by the plants. They bring mineral and organic complements in order to increase its yield and its gustatory quality.


Practical information:

On our fertilisers, numbers are written this way:4-1-8. That means : 4% of N (Nitrogen), 1% of P (Phosphorus), 8% of K (Potassium).

Fertiliser needs for the cannabis are simple, but change according to different periods (growth/flowering). - Early in its life, it needs root-stimulators like the StartBooster of Aptus, the Voodoo Juice of Advanced Nutrients or the Hesi complex racinaire of Hesi.

-During the growth period, you will have to give your plants specific fertilisers rich in Nitrogen as the Terra Vega of Canna, the Complex croissance of Hesi, the Iguana Juice Grow of Advanced Nutrients, ...

- During the flowering period, your plant will need Phosphorus (P) and Potassium (K). However, the Nitrogen rate has to be as low as possible. Be careful! An over-fertilisation is very bad for your plant. Thus, you have to respect prescribed doses!

You can also use fertiliser complements including trace elements that are necessary for your plant: boron (b), molybdenum (Mo), cobalt (Co), Iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), ... All of these complements are proposed throughout the ranges of fertilisers or high quality boosters such as Aptus, Advanced Nutrients, House & Garden, ...

We are 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 nutrient selection that you need for your culture.
