    Default Answered: Led light question

    Well I will start by saying hello and glad to have found this site. I have found a lot of intel that has helped me on my indoor go.

    So on to my question. I have a 900 watt over two gg4 in waterfarm 4 gal linked to a Rez to supple the buckets while I’m away at work for the week. My tent is a 3x3 by like 5.6 I think it is. And the mother room attached in a 1x3 with two more water farms. With a 600 watt led for veg. So I’m trying to figure out what the best height is to hang over my canopy. I’ve heard 18” and was told to use an app and measure the lux on top on the canopy and was told a maximum of 50,000 lux but when I read it at 18 “ it was measuring at like 10,000 lux and I tried lowering the light and get more lux but notice that the outside barely gets light. If someone has any info that would be great.

    Intensity Vs coverage is the trade off you have. Not much you can do with out adding more lights.

    I flower at 12 inches with Mars Hydro

    Hi mate, the good news is that your plants see a lot more of that light than your lux meter does

    Oh nice that makes sense and will see how that works. my brother is running two mars 600 watts. I would like to add another 900 watt or a hps just not sure about the heat it’s a bit of a problem for me right now. Are winter this yr is so mild and I was just heating my top floor of the house but going to have to exhaust it out

    Just remember those led figures don't mean very much

    The Mars 600 pulls around 250w
    The 900 around 400 I think
