Susbstitution of light sources

Explanation of ppf and ppfd on well established sizes used for grow-tents


The correct substitution of an existing HPS lamp is no rocket science. Especially indoor gardeners often ask us about the required number of SANlight modules for replacing their existing exposure systems. We would like to give you an overview of the most commonly used standard systems for Indoor Plant Breeding.

To help you compare the system better, we provide  the most important data such as PPF, power consumption and PPFD plots
