2. Mixed lighting is nothing new even trulieves largest building is mixed hps snd led. 😂

3. LED for veg and HPS for flower

4. Most likely the benifet comes from the ir in the hps lights causing the leaf to heat different and plants to transpire diffrently , that was the first thing I noticed when going from hps to led and I run mammoth so my spectrum is a good match to hps , wouldn't it be more cost effective to use some of the newer ir light bars over hps

5. LED grown buds have no top end on the effects, very pretty though

6. The sun gives yuo 2000 umol of ppfd, canabis can use 1000, any ligth of 800-900 gone work , over 1000 ppfd yuo need co2
   Thats it

7. guy i run mh and hps ….always kept it quite that is use 200 what tunable and always have nice crops

8. I have grown my own weed indoors in a 4'x4' grow tent using either 400 watt, or 600 watt HPS lamps for about thirty-five years and have often considered trying LED lights but have never found a good reason to change what I am doing. My results have always been very good. Also, every LED manufacturer claims their lights are the best, and they are all expensive. I wouldn't know who to trust. I will just stick with what I know.

9. I prefer CMH.

10. Iv got lumatek 630s. Iv always had great results. Why doesn't many people use them.

11. He said 5.5 ec ? Right?

12. i use cmh with leds,and prob had my best grows with both in use

13. HPS ARE THE BEST MY OPINION

14. What is the best option for I'm already homegrower at the moment when it comes to LED, UV snd far red. Is there a mixed lighting setup for a 5×5 or 10×5

15. As a home grower, what's the best option to add far Red during the night? 5×5 tent.

16. I see smaller buds from LEDs and larger buds from hps I figured mixing them would be great I plan on it

17. They aren’t wrong about the lighting. I’ve heard about the use of reds before. The marketing talk of these guys is very off putting. Trap rooms, really? Guys like that are in this strictly for the money. Culture vultures.

18. I steal a lot of business from led growers and dispensaries. Hps and old skool strains are doing it for people. I ain't losing any money. Quality over quantity.

19. Metal halide in first 2-4 weeks vegs shortens my flower time by a weel

20. smart idea guys mimic the sun well done with the reds nice now ramp down time like outside at the end of flower more solid buds more tricheome developement more turps you guys doin great keep it up FREE THE WEED! PEACE!

21. Finally someone taking about mixing LED and HPS together. I've done it for years and it really is the best of both worlds. LED alone doesn't compare.

22. These guys are smart smart. Obviously smarter then most.

23. What brand of led and model for veg & flower

24. It's spectrum and intensity… that's it. Can LED give you that? Absolutely. There isn't a spectrum you can't get with LED that you can with HPS. Just more bro science.

25. On paper led is king, on paper a high end led light emits 220 lumens per watt, while a high end hps light emits max 160 lumens per watt. A led produces more "light" per watt of electricity consumed vs HPS.

26. I run both HPS and LEDs in my grow and have no issues at all. I get the best of both worlds. Stay Frosted!

27. Sounds like u guys have never heard of spectrum tuning LEDs like scynceled or grandmasterled

28. led by far

29. led and cmh

30. Gate keeping pos

31. I get 1.5gr per watt with lm301h… mpossible to do it with hps.

32. This is insane.

33. The humidity argument depends on where you live… I depend on my HPS lamps to keep humidity down because I am in a coastal city and our average daily humidity is 70% – 98%… Flowering 60 plants with no humidifier at all.
