Cob advice

[I like Cheese]

Hi Guys

I have a veg tent that is 0.8 m2 and i am wondering if 4 cree cxa 2540 5000k cobs would be enough to cover it. i am certain there are better cobs for this out there but, that was my budget.

Thanks in advance.

That will do for a start, but you will want more for flowering & in a lower kelvin range

Thanks for the reply.

I have 8 cxb 3590 3500k in my 1 m2 bloom tent. The 2540s are just for veg.

They will work well fot the first month , provide a good enough footprint for the tent size really.

powered to 35w each its about 35 sq. ft ,the suggested minumum for lesser led lights.

They are running at 30w each. I don't know what par watts or ppfd they will give. I will try it on my next grow. If is not up to the mark, there is a spare driver in the case so i can just put 2 more cobs in it.

Hell ya thats a great thing with these cobs is that its so easy to add more modules.

I just made up four of the cheap 100w cobs powered to 45w that are hung over each plant / seedling to start with.

Im about to assemble 16 cxa2530 ( 65w chip ) onto 8 pc fan heatsinks that will be used in half the tent.

Really looking forward to this up coming all led grow , used a combo of hps and led last few times.

Thats them hanging above the plants , its nice having a low watt option for the seedling stage

Very cool. I hacked a 200 watt led. The 4 2540s and holders cost 80 euros and that was all. I took the LEDs of the Ali plate an sanded it.( Should have bought 6 now thinking about it). If i do buy 2 more i think i will also buy a hlg 120 700 and run them all from 1 driver.

I have 4 plants that have been in 12/12 for 2 weeks in a 1 m2 . They are under 8 cxb 3590 3500 k running at 50w. I am really hope for good things from them.

This is my 3590 rig

Plants are looking healthy I like your panel She is beastly.

The cxa models can be found for a good price since the cxb came out , good for the diy builders with less money

I have two cxb 3590's laying in wait due the to price of them will be buying them in small batches collecting them before building a panel. Its a long term project for me..
