I have been using HPS for nearly 10 years with no real problems I have just changed to LED because I changed strains and found that the new strain was not liking the heat in the summer , I was blown away by the way the plants looked after the first week but now 2 weeks into flower the stretch is something Ive never seen , On HPS I would grow until canopy was 30cm high then turn to flower end up with a finished height of 80 - 90 cm , MY first grow with LED and 2 weeks into flower and canopy is already at 80cm this would be fine as plants are looking sweet but I am limited to height and they are going to outgrow my room . I will adapt on next grow but it seems there is a bigger stretch with LED to HPS
