The device you use to hand the light.
Metal grate type thing.

In my perspective and this is just speculation, but here is my theory regarding cheeper 70lm/w type LEDS.
A CXB or Vero Bare can be at 10" at good Umol. Now the cheep COB run about half that umol at that distance, somy theory move then 50% closer and you should be hitting similar umol.

Thats my big problem. All ypou need to do is move the LEDS closer.

I will be testing this theory this year in a side by side in a 3 x 3 9 plants coco.

Would love to see this grow :)
Got it from a local store but its to expensive gave 20 euro for it, got a freind whos working with metal he will bend me some new boxes for the next one's got 5 panels i need to make this mouth for a lokal headshop.

Good job. This is great practice and a learning experience. Let us know how the plants react to your new light set up.

I may try this $220 - three light kit for my first one using Vero 29s/ For about $70 more I can get solderless Crees.

The 3590 is only 5% more efficient at 2.1A than the Vero.
Personally CXB isnt worth the premium price, but thats for you to decide.
Also I hope your in the USA as duty is a bitch in Canada.
Ill also never order from
im just done with the panel atm im making a aerophonics system for the tent pic's will come soon :)
I highly suggest you get a fogger, man they made my roots crazy last time in my aero.

I love Coco full hydro.
Not a fan of true hydro at all. Not a big risk taker in that department.

Yeah I am currently waiting on irrigation suppliers to setup a 3 x a day Coco feed. Hate hand watering and hate all the runoff.
Cant stand hand watering especially in flower. I know some guys running like 6 feeds a day which is quite intense.

Ill be running timer as well.

Put those chips on an adjustable power supply and turn it down low enough to be able to see the diodes. The cob is so bright you'd think it was working perfectly........ I'm willing to bet 25 - 50% of the diodes don't even light up! what they are selling cheap are factory rejects.

just wanted you to know what your dealing with. They are a waste of money if efficiency matters to you. If not, then your better off with HPS
