Heard good things about Mars Hydro, but I've never tried them.
I had offers from Mars and Viparspectra and also Unit Farm.
Mars backed out as soon as they heard someone else was sponsoring me.
I have the Viparspectra XS 2000, sponsered by Emily, Great light, dimmable.
Currently growing 4 autos under them and just finished a grow of 4 autos, super happy!!
I have two of them in my 4x4 tent. I also have a Unit Farm UFS 3000(200watts)plug and play,
in my 3x3 tent, sponsered by Justin, this light really surprised me. For a light
that doesn't break the bank I give it a 10 out of 10 so far,I've only used it for one complete
grow, Unit Farm test grow #1, check it out..
Later!!
