9 Pineapple Express

I notice them a little small and they have not grown as much as I would like. So change the light from 400w led to 315 CMH / LEC. With the led I was looking for a shorter nodal distance and a lower height of the plants. But seeing that they did not develop well I could not resist seeing them not quite well and returned to the CMH / LEC. I think they are recovering. I will see what I do with the height of the plants and the heat generated by the light. Here is spring and summer is coming (30 Cº). This week I made a watering with Top Veg at a much lower rate than the manufacturer recommends. We read in a week. bye
