I am looking at using LED`s in my grow box(48"x48"x96"H). I have been using 400w(18 hours) for veg and 600w(12 hours) for flowering, but I am having problems with heat oh what a surprise. Apart from the heat and electricity bills I normally get quite a good crop. I would like to change over to LED`s not only for the heat issues but for the stealth. Can anybody that has experience using these lights give me any suggestions on what type/brand and supplier and they use. It would be greatly appreciated as I don't want to go out and spend a fortune and not get the right gear. Regards.
