You must be not be familiar with growing marijuana with LED Lights and Solar panels bamsterdam, I don't think CANNdy is a loss considering I grew and I made all my money back on panels, lights, nutrients. With 12 plants, there was more than enough to go around for patients
One of the drawbacks for LED's can be the initial start-up cost Many of the well made panels that put out what they advertise can cost up to 3-4$ a watt. And some panels have light spectrums that aren't exactly used by the plant efficiently (uv, if). And many people are getting ripped off on eBay buying "300" watt panels that pull 130-150 from the wall including fans. I bet having solar panels makes power consumption a lot less of a concern though
It is a new and emerging market and will go through many trials and tribulations before consumers are taken care of properly.
One of the things people are doing is making there own panels using COB (chip-on-board) technology with white light targeting spectrums and getting some pretty amazing results. Check out rollitup.org 's LED section. Some awesome guys over there making great guides on DIY LED's.
And don't worry about bud prices being high. I think in a few years the price will plummet with all the surplus MMJ that will be coming to markets. (I could be talking out of my ass on that one )
