I can't say enough about the Advanced panel I have, and I have to believe all of their products are this good. What impresses me most are the tight nodes my plants are growing. I'd expected them to be much more leggy. I'm very happy with this light.
The Mars-Hydro line consistently gets good reviews from members using them, myself included. I have a couple small 300 watt panels that are fine on their own for a good-sized plant. Even members who have problems with a panel appear to get satisfaction from customer support. For the price, they're hard to beat and they are
sponsors, so they maintain a presence on site.
The cannabis you'll grow will be so superior to what you can purchase anywhere that you'll be shocked. That's not even taking into account the romance of your first harvest. You'll recoup your set-up expenses within the first two grows. It can get expensive, I'll give you that. We keep expanding and buying "MORE LIGHT!!!"
