Hello everyone from Ukraine. I want to share my photos, experience and write at least. I am a batan and the topic of growing indoors has become very interesting to me. I had to study a lot from batanics to electricity, light and a bunch of everything I had to do in the current situation in the...

Looking at the various uv and limited spectra t5 lamps (denoted by "pure" or a nm number like 430), and 10000k / 14000k "finishing" lamps. @RM3 do you have any experience with these or other options like repti-sun? Trying to balance quality, quantity and cost. Thinking about 4-6 2ft tubes to...

I would like to add some "terpene enhancement" to my light bars. I just don't know what chips to get and how hard to run them. I'd rather not roast my ladies in an attempt at making them stronger. I'm sure some of you have learned the hard way. Any chance I can learn from your mistakes...
