That was an old grow this is the last and not bad but could have been better

I’d like a deepish canopy yes, the fixture is 1m x 1m in a 1.2 x 1.2 and as I’m running 8 that will be topped once with at least 4 week veg from seed I will need the penetration. Only thing I can crank up are the cobs. I’m limited to 220and 180 on the boards and have the cobs at 225 now drawing...

Sweet thank you, just what I needed to be told. So would I be ok leaving them at 36inchs and letting the plants grow up to it do you think?

This is what I want to do but need to know roughly what wattage to run each, thinking could lower the power to the cobs. But if running the boards at 50w each where would I need the cobs at roughly? Thanks

I want to run them so I don’t have to adjust the light cause it’s a pain in the as lol

@CobKits how would you do this then? Just starting a grow now with light 36inchs above newly transplanted plants. Thanks

hiw does running leds effect the way you grow? As in, do you need to run the lights closer for the same given wattage? I have 9 cxb3590s, for the purpose of this (they are copies) I have 4 fusion board copies and 4 qb304 copies and was running Roond 600w on the whole fixture which was 360w...

Done, I keep seeing him spouting rubbish

Top feeding and just looked couldn’t see a far red cob would you have a link to them

Getting 30000 lux at the top, but you are right after looking properly only 3 are going pale, so must be hungry and they are 12-20 inch’s away

just thought I’d described this as yellowing but it’s more like where they fade light green like their getting too much light

Thanks. Took a little while to get together just contemplating a far red initiator to cover the fixture for after lights out

And the cobs are only 300w between the 9 so reflectors help the intensity, 200 through the mixed boards then 130w though the 3500k boards all drivers are 1400ma dimmed or full on with the mixed boards

Will get some when the lights come on thanks

as above, should I get yellowing with 600w in a 4x4 tent? Running super efficient and quite high aswell, can’t bring myself to lower the wattage lol

So my fixture is now 1m x 1m in a 1.2 x 1.2

Look at the iws brain bucket for the drip and drain, has a float valve when it gets there it empty’s wherever you want it

So iv spread everything out now so it’s not so cramped into a frame that is 1mx1m so the cobs are roughly 16 inch’s on centre with the boards in the centre, I think I’m going to source another driver so I can run the boards at 300w and then 100w or more to each set of 3 cobs. Seems much more...

Could be that if I measure at 12inchs the lights don’t blend enough, maybe il try 18 inch’s and see how it goes

I have a lux meter but with the 3k cobs and 3500k boards if they match I either need to run the boards at 20w or the cobs at 160 per 3, the 3k is nowhere near as bright as more red. I would use that if they were all the same spectrum Thanks
