Lou i checked around for over 6 months before deciding on blackstar. I was an optics and laser major in college and know my lights and lenses. I found by talking to people that owned other panels and looking at the guts that you are essentially getting the exact same thing light for light with the exception of the ones built on us made boards which will cost you between 3-5 times the price for the rest of the parts still being the EXACT same. only changes are gimmick items like a switchable spectrum for veg/bloom or finned heatsinks for more heat absorption. These tactics are garbage and misleading. Even with photo plants you don't need to use different spectrums with leds. The % of light absorption is rediculously higher than any other system out there minus plasma induction lights which are at the stage leds were 2-3 years ago, a great concept but FAR too expensive until the tech gets out more. Honestly I personally wouldn't use anything else that I personally have seen for what the lights purpose is which is to grow good bud. It does that perfect for a lot cheaper than a lot of companies. Quality is great and all around everyone I know with them are extremely pleased with the results on autos and photos. But honestly research for yourself and see what is a good fit for you. No two growers will ever be the same and your climate/location will make all the difference in your personal setup. With that being said just look up blackstar led in an ebay search for the number to gotham hydro. Talk to Victor and he will hook you up with whatever special they can pull at that time. Just a disclaimer I do not work for any entity that makes or sells the blackstar lineup. I have been getting criticism on some other boards I'm on as a rep when honestly I'm just a knowledgeable person who will not be swindled out of my hard earned cash when i could spend the extra on fans, cords, nutes, soil, pots..... the list goes on and on what all you need to save your money for when you grow. Lay out a full budget and see what all you can get for that price by researching heavily. He with the most information is king when it comes to growing quality cannabis and for setting up a grow area that you will not regret. I made mistakes and have upgraded equipment and spaces 3 times now and it cost me quite a bit of coin. But honestly think of how much you spend on bud a month and put that money into your grow space as you pull bud and you will have a monster garden. I started with 3 plants and 1 100w led unit and now I'm about to have light movers and multiple panels running 24/7. It is a journey to have a great grow room and you literally reap what you sow. Enjoy the ride and remember you will mess up! Just learn from your mistakes and move on. If you need any help stop by and post in my perpetual garden thread in my signature. Myself and others will be more than happy to answer your questions. Welcome to the site and happy growing!!!!!
