Lumens, Par, Watts, and etc. aside which light performs best for indoor grows?

Hi bro, thats a tricky question, as you have seen, there are plenty if great growers that use different lighting methods.. The light is but one piece of the puzzle. I wish a had some more precise info for you but i was killing it with HID, now im dialing in a new cob lamp and struggling..peace

Dealing with cob problems myself. With the metal halide it was pure green growth, no problems. Dialing in this cob is a pain, have some bleaching going on. I have 5 cxb3590s turned down to 125 watts at 25 inches from canopy and still havent cleared up. New growth is still somewhat bleached even after upping cal-mag.

Exact same situation you are in. With the metal halide it was pure green growth, no problems.

New growth is still somewhat bleached even after upping cal-mag.

I done a custom built light and have them at 43% efficiency , i started out at 45" above canopy and now have them at 20".. Growth is good as well as coverage, no issues with bleaching yet.. This lamp has 10 citizen cobs with two drivers

Looking great budelee, Might have to bring the lights up a little higher and see what happens. Thanks for the info!! These cobs sure are a lot brighter than the halide. Still learning

So these lights you are working with,did you build them or are they from a vendor??they sound really interesting

I bought them from Alibaba, found where to buy and how through a member on here by the name of "realstyles". I built the support system using two pieces of angle iron in a cross configuration with the driver mounted up on the wall. Got that idea from growmau on youtube. So far I love them, however still working with them. Its not like metal halide because as you know every setup is different and i dont have a par meter so its been hit and miss learn as you go type of deal. I went the passive cooling route, thinking i should have went with active cooling because those lights do not get as hot as the metal halide which created heat that turned on the circulation. Trying to save as much energy as i can without causing problems.

I hear ya on the learn as you go part, i built mine big enough ti cover 20 square feet which i use to grow 6 plants, rhe plants love the light and i could have prolly gave them more area,,im about halfway thrumy first grow, so i'll have an idea of what to expect in about 40 days..

you need red!!! the question is how much red and how long do they need it!!!

I added some red for 1 hour at lights on and 2 hours before lights off!! it fixed my problem... this room behaves like a HPS room now but no heat!!.. try it!!!
You have to have red to grow "good" plants!!!

I get all sorts of cool colors!!!
