So people that dont know, quality cobs are the most amazing grow lights available for the price, Hands down. Efficiency, spectrum, control, customization. I wanted to share my build and time with these little gems.
Lets look at the spectrums here first.
The McCree curve is what we are trying to achieve here
You can see that cob lighting fills much more of the gap than hid. Now there are many more options for cob spectrums than what is shown here. Vero now actually has a 1750k chip.. Then we have 70,80,90 cri options.. I did say customization..
Here is an efficiency chart comparing some of the most common quality cobs.
So lets go through some of my build..
16x vero29 se 3500k
4x meanwell hlg240-1750 b drivers
Built into 2 36"*36" panels to go in my 8*8 tent. I only use a 4*8ish space inside.
So i went from 1000w hps at around 20" away to 330w over 8 cobs at 30-36" away on my 2 final girls from last run and in 12 hrs they were showing severe signs of light stress. I had more tacos then the local burrito shop.. So down to 250w i went and they were praying like they never had b4.. Extremely powerful little things.
Now these really aren't that hard to build.. Much , much cheaper than high end prefab leds, and you can easily get a much higher ppfd for your grow space.. And if you dont want to tackle the build yourself you can order a timber kit in the US (pretty expensive though) or there is a guy on here from canada that builds and sells quality cob panels. Also check out autocobs, great guy with a quality product as well. If your going to try to build one, Rapidled.com is a great place to start, they have everything you need to get going besides aluminium angle..
Please, please, please, people, think twice about buying blurple crap..
White light is the way forward, blurple was a bad mistake...
Thank you
