Led or something else ?

25 posts in this topic

Hello growers! 

 

I'm hoping on some information on LEDs as I've never used one before and thinking of buying one. 

 

I'm setting up a 2.4 x1.2m tent with a 600w HP's in the one side but for heat reasons I'm thinking of going for a marshydro 2 1600 in the other side for 4 plants . As it's a big one with alot of power and looking for a good crop!

 

If anyone could advise me on if it worth getting this for the money £300. Or trying something else ?

 

Atb guys! 

Thanks Fatman!

Thanks guys! 

But I have to extract into the loft as no chimney or anything to vent outside. Also a copper lives next door lollollol , been doing for over a year with no problems but don't want to light the place up with 2 going lol , it's vented soffit but too risky with 2 going . Also the walls are paper thin so don't want to big extraction going haha 

 

Atb guys! What's the best led for coin also boys?

The claims being made about LED lights producing less heat would defy the laws of thermodynamics if true.

The best LED grows I have seen reasonably convincing evidence of are yeilding about 30 percent more plant matter per watt - for seriously high-end COB units. (Greengenes garden on Youtube)

 

The cheaper units seem to be roughly equivalent.

 

This recent paper doesn't find very much difference :-

Bottom line is buy another HPS for £70 and fix your ventilation with the money you saved.

Agreed, LEDs have their place, but lighting a big space isn't one of them.

Cheers boys but.. won't a marshydro 2 1600 be good enough then? For the 1.2 x 1.2 m space ? 

It's just I got heat issues and need something diff bit will be powerful for a good yeild. 

 

What sort of kit would you boys use for this situation if it using LEDs ?

 

Atb!

Only 4x4 ?

Get a parabolic reflector for your existing lamp.

Thank you pal! In a 2.4x1.2m tent would a 6inch on Max be okay? Or 2 6inch filters hooked up on to a 8inch fan with a duct splitter ?  Like a Y

 

Atb man

@Autofatman Not saying the chinese blurples wouldnt do it.. They will work but if you have it sitting next to a 600w hps ur going to See a big difference and probably fall for the hps lol

 

If i had the time and money i would make a custom Cob LED for that size
