HPS or LED

MS2845started grow question 4 years ago

Hi I wonder if its worth swap from HPS to LED's. I heard you can get 2g for each watt with leds. When with HPS 0.5 to 1g each watt. And you dont have problems with the heat which im having now I can't lower the temperature I'm on 32/34. Anyone could give me an advice 😊

Salut, Je tourne avec les led de MarsHydro, model TSW2000. Sa ne chauffe vraiment pas beaucoup, fini les problème du a la chaleur. J'ai était obligé de rajouté un chauffage pour l'hiver. Oui il parait que l'on peut obtenir 2g/watts, mais tout dépend de tes connaissances des techniques dans la culture du cannabis. Personnellement je conseil les led, et particulièrement MarsHydro car leur prix sont très concurrentielle

PAR/PPFD and light height PAR/PPFD: does light height matter if your PPFD is in the right range? Another way to ask: is 300 PPFD @ 2 feet the same as 300 PPFD @ 20 feet, or are there other factors involved? (assuming heat, C02, all other non light inputs equal)

Too much light ?So started my second run and got everything dialed in but this time I’m running with spf-1000D and the normal spf-1000 is that too much light for the plants that would slow them down ? Together the lights should be around 200w

Is that just a light burn or could it be something else?One bud in the middle of my plant is much lighter than all the others, which all look healthy and green. I think it was due to the too small distance of my light, which was only 20cm (8") between canopy and light. I have now moved the light to 35cm (14"). What are your opinions?
