Buying Grow light fixtures.
Hello, my name is Shawn and am an avid plants man of 10+ yrs.. I was wondering if you would be able to help me narrow down my options for a grow-light fixture. I have read several comments regarding the different lights and the photon efficacy of phosphorescent coatings and what not. I believe I have gained a new respect for an elementary-physics indoor lighting point of view to growing empowerment. I am a seasoned grower of all things in and above the soil. After several years, I am now wanting to enjoy gardening indoors again. I would be setting up a 4'X 4' in-home area for mature full-sun blooming plants. For cold-season growing mainly with a propagation, "fragile-plant", and terrarium setup year-round. I have used a 400W MH in the past but am looking at possibly a dual-spectrum 500W HPS/MH unit for around $350.00. I have also considered a T5 6500K/3000K 4'/8 bulb unit for $265.00. I am leaning toward the T5 unit because of the "safer" heat-spread. Also tempting is the new "Blue" HPS bulbs though and possibility of only needing to have a single 400W+ HPS "Blue" hortilux (or similar) bulb for around $250.00 +/-. might be more efficient in getting the photons the plants really need to thrive, lush green and capable of bloom. If the HPS + or Dual-Spectrum units are the way to go, rather than the T5 "6500K/3000K" 4'/8 bulb fluorescent, are the new digital ballasts the best efficiency, also considering bulb-life? I am just curious as to what you would buy if you had the extra-cash just for grow-light fixtures. Let me know what the best bang for the buck would be in your consideration. I respect your point-of view as a fellow plants man and hope for nothing less. Thank you. - Shawn
