just after some opinions on height from canopy. Running cobs at CXB3590 at 1400Ma and 4 boards at about the same total of about 750w. Iv decided to leave the reflectors off this run as they seem to cause problems. At the moment it’s 18 inch’s from the tallest plant and about 24 from the short ones

That’s good, I received my drivers but was sent non dimming so i now have 2 single sunboards one with 87w and one with 82w. Just not sure how they will get on at the higher amperage heat wise

Was wondering what 1 sunboard at 75w was capable of, nice work

Iv just ordered some elg-75-36 for some fusion boards, could be used on a 36v cob upto 75w and has the 3-1 dimming aswell

Thanks but I have the lights already, 2 boards on a 185-1400A 185w max at the walk. May get a talker tent to veg in anyway

I know but this is what I have,that’s why I’m asking what power lol, so 40w? 50w?

No plants in there yet but testing the temps at 80w, may turn it down to 60w, mainly for starting plants to about 12 inch’s tall. Thanks

Without searching the whole thread, 2 qb304 in small 2x2x2ft cube, how many watts should be ran for veg?

Anyone used the sonoff WiFi dimmer? I see it somewhere but can’t find it again

But I do have a lot of light dimmed down, everything is about 35w each so pretty efficient, if I turn everything upto 1400ma things do get abit toastier lol

I have that fan on my intake, I have rvk6 L1, turned down, but if I put my 5” rhino which is quite powerful I can get the temps down, even at full blast, so il be sticking with the big dog :)

Mine at 650w in a 4x4 tent sits at about 26 with no extra heating and my extraction on 30%

1m x 1m the fixture is, just over 1000 into it

thought I’d make a thread specifically to show your hybrid builds and so I can get some ideas where to go with mine. I’m talking cobs and boards on one fixture. Here’s mine, I’m always looking for ways to change it up.

Try plgrowsystems for a temp and humidity monitor, check it through WiFi or on the screen and only £35, comes with a air temp and humidity probe and a waterproof probe for the water

Lol straight over my head lol. So at 18 running the boards at 50w each what would you suggest to run the cobs at, 18inchs is a good distance for flowering but I can’t really move my light easily so just need the plants to grow up to it. Iv got the cobs at 25w bare at the moment as suggested by...

In the uk but thanks for the offer I have a lux meter but have 3k 90cri cobs and 35k plain boards the the mixed boards so not sure how I’d work it out

I do want to run at about 18inchs but not sure how hard to run the cobs for that hence the reflectors. And I wish I could bring myself to pay out on a par meter just to set my lights, maybe someone should get one and rent it out lol. Also I can adjust the drivers so ideally would keep the...

Sweet but shouldn’t you make your own post mate? Your light has nothing to do with my question lol

Not interested in hid anymore, only kit that has my eye is the helios de but I keep telling myself I don’t need it and will stick with LED lol
