Shifting NPK gears
As we progress into the critical juncture of our summer crop growth cycle, we are initiating a crucial transition from the vegetative stage to the flowering phase. This shift necessitates a strategic adjustment in the nutritional regimen to optimise plant health and maximise yield potential.
Currently, our crop, consisting of over 2,000 plants, stands impressively at heights exceeding one metre. These robust specimens are ready for the next stage, where the focus will pivot towards flowering. To facilitate this transition, we are recalibrating the nutrient mix to reduce the previously high levels of nitrogen (N) and enhance the supply of phosphorus (P) and potassium (K).
Nutritional adjustments:
Nitrogen (N): During the vegetative stage, nitrogen was pivotal for promoting vigorous leaf and stem growth. However, excessive nitrogen can inhibit flowering and lead to lush but non-productive foliage. Therefore, we are now reducing nitrogen levels to shift the plants' energy towards reproductive growth.
Phosphorus (P): This element is crucial for the flowering stage. Phosphorus supports the development of strong root systems and is indispensable for the formation of flowers. By increasing phosphorus availability, we ensure the plants have the necessary resources to initiate and sustain robust flowering.
Potassium (K): Potassium plays a key role in enhancing the plant’s overall health, akin to bolstering an immune system. It helps in disease resistance, which is particularly vital in the hot and humid climate characteristic of this season. By increasing potassium levels, we aim to fortify the plants against potential pathogens and environmental stresses.
Monitoring and outcomes:
We are pleased to report a remarkable success rate: 99.6% of our plants successfully navigated through the vegetative stage. This high survival rate underscores the effectiveness of our current cultivation practices and sets a promising foundation for the flowering phase.
We are still adding fertilisers and nutrition manually, as seen here, but very soon, we will be introducing our automated system, which will allow the plants to be fed through the watering system. More on that shortly.
