3500k works fine for the hole life cycle. If you want a light which is just for flowering stage i would use
1) 2700k or 3000k, i think there is "no big diffrent".
2) if you have a "big" tent and the possiblity to build a mix, i would use some3000k and a few 2100k. I also would recommend to run them on 50-75% of full power and use some more cobs :+1:
(100% Power does not give you the best output. Sry but i cant remember how much we used for a Friends light :see_no_evil: but it was something we found out by some research :sweat_smile:)

Hello ! Depending on how much blue vs red you want in your spectrum. 2700K more red for pur bloom with more stretch if used in vegetative stage , 3500k for less stretch at every stage with more blue in it . I think it's what mater here so the 3500k is the perfect balance between a mostly red light and a mostly blue light. I hope it will help you :grin::+1:

@Black_Magic to put it simply Flowering plants do best under a light wavelength(spectrum) that is between 620- and 780nm. This 'warm' reddish wave length you need can be best achieved under a 2000-3000 Kelvin(color temperature) spectrum or as close as you can get. To answer you question a little more specifically choose the 2700k HPS for best result in flowering! Happy growing :sunglasses:

I think most people and sources will recommend having your lights have a blue/white quality for veg and for bloom a higher red/orange lighting. Leds sometimes have the options if switching modes..these are nice because you wont have to change the light just the setting. With some uv/ir lighting is best. I think picking either the 2700 or the 3000 would be best.
Best of luck with the selection process. :v: happy flowering

Hi @Black_Magic! The 2700K color spectrum will be the most appropriate for your blooming tent (warm, yellowish/redish). Hope this will help, happy growing :facepunch:

Take the 3500k, only more light is more light... and in flowering stage every lumen counts.... happy buying^^

Hey @Black_Magic, i was asking the same question to replace my 600W. I found some scientific research about LEDs and spectrum and it's very confusing, my conclusion is that what matters in the end is the average spectrum and intensity. So what color is the sun ? white right? so why should your led be purple ? that's why I'm going with fluence or fluence-like LEDs - fluence is an LED company doing some lights research, very interesting you tube videos sometimes hope you can find them ! Fluence-like LEDs basically they are panels of LED strips, easy to manage by one person 1x1 m , so it fits perfectly inside a tent and they do a better job of getting light in the dark corners of the tent. some research says that actually they got 30% more yield than 600W HID. the fluence costs something like 1500 and it should be worth maybe 1200, check this site they have some of their own models and they are something like <500 plus shipping. Good luck migrating to an LED ! remember to keep a much close lamp to plant distance if you want good results ! hope this helps my friend ! :rocket:
