Welcome to the site, and yes, technology has changed a TON since the 90s. You will be learning some new things, I can guarantee this!
Yup, so far there is. Since my first post and my last post. I have found many things different. From types of lights, to the spectras they produce to better understandings of spectras in general. Technology in that area alone has changed a great deal. I guess theres no more trying to steal parking lot lights lolz (joke, i would never do such a thing?). Though, what has caught my curiosity the most are some LED's. Though I have found many different name brands, but it just seems many are not as good as you would think they are for a LED type light. I've been tryn to find some kind of light that would work from seedling through flowering. I know blue's, oranges, and some red is good. But the ones I have found thus far, provide green's with blues OR red's, with some white and/or yellow and some other color in the sprectrum that isnt really needed. I dont need a huge light, just enough for testing, maybe something that could cover 2 sq'. If you by chance have a hint or a blues clue to help point me in a better "name branded or non name branded" direction for some "better quality" LED's I'd appreciate it
