Luz en distintas en fases

genetics are king. yes, the CCT of the light may impact the plant in small ways. It will not turn a bushy plant into a lanky plant or vice versa. The factor will be so small that if it is simply more convenient to use the warmer CCT hps, then go ahead and do that. DLI is vast majority of what dictates yield. i've used 2900K - 3500K and i see virtually no difference with my eye with clones and seeds of same strain etc over 6 years. That doesn't mean there are not measureable differences ( i do believe the science of it), what it means is that those differences are small - proper perspective on them. often you need a much weaker light early on, so 2 lights is usually a good thing just for that reason. as they grow out and near flower, you pull out the big boy light. You often need 150% power going from 18h to 12 h cycle too, in order to provide same DLI as before.

Hey amigo! Sí, existe una diferencia significativa entre el uso de lámparas de sodio de alta presión (HPS) en el cultivo de vegetales y en el uso de halogenuros metálicos (MH) en la flora en general. Las lámparas HPS, que emiten una luz más cálida, son más efectivas para la fase de floración, promoviendo un mayor desarrollo de los frutos y flores. Por otro lado, las lámparas de halogenuros metálicos, que emiten una luz más fría y azulada, son mejores para la fase vegetativa, fomentando un crecimiento más vigoroso de las hojas y tallos. Esto se debe a las diferentes necesidades lumínicas en cada fase de desarrollo de las plantas. Buenos

HPSodium have more red light and are better for flowering. Using MH lights for flowering, while ok, are not ideal and can lead to flowers that do not reach their full potential. Again, while using HPS for veg is ok, it can cause plants to stretch and not reach their full potential either. Using MH for veg and HPS for flowering is the best idea and will cause plants to reach their full potential.

The difference in light colour makes NDl light suitable for flowering, because of the orange/red light. MH light is better for veg because they have more blue light causing shorter internodes. So using MH during veg causes shorter, more bushy plants, and NDl causes more stretched plants.
