Temperature, humidity, CO₂ and pH are four key parameters that determine the growth rate, plant health and yield in indoor cultivation. Even the best lamps, fertilisers and substrates will not produce the desired results if the growing environment is not stable and adapted to the needs of the plants. In this section of the guide, we explain what the optimal values are, how to measure them, what to avoid and how to use CO₂ to increase your yield b

Fertilisers are another key element in maximising yield. They have a huge impact on the taste, potency, quantity and aroma of the final product. There are many ways to classify fertilisers used in cannabis cultivation, but we use a practical classification based on real-world application.

After selecting a grow box and a suitable lamp, the next important step in maximising the quality and quantity of the yield is choosing the right pot size, transplanting early into the final pot, and selecting the right substrate.

Choosing the right lamp is one of the most important steps in indoor cultivation. It is the power, type and quality of light that determine the growth rate, yield and aroma of the plants. In this part of the series, we explain how to choose an LED or HPS lamp for a specific grow box, which parameters are key, which brands and solutions make sense, and which to avoid if you don't want to lose weeks of work.

How to increase your cannabis yield — choosing the right grow boxThe first step to obtaining a large, healthy, and high-quality yield is choosing the right grow box, i.e., a professional grow tent. A properly designed grow box guarantees full control over the plant environment — from lighting and ventilation to odor control.
