Wow!! This took so much research by you....thank you so much for enlightening us in the different kinds of light needed for our African violets. I actually learned a lot, too!! Thanks again!!!
That's a great resesrch of yours and a superb presentation! 👍👍 Have you also tested grow lights which give information to PAR 380 nm bis 780 nm and PPFD about 600 umol at about 45-60cm from the plant?
Thank you Minh for taking the time to do this presentation. I have listened three times and will listen again. I have some LED shop lights that fall in between this. 3600 Lumens about 4200k-(according to packaging) and one that has 5000 Lumens with 4000K. Should I be supplementing Red, Blue or Red and Blue on these shelves in your opinion? thanks!
Hi Krissa! Sorry, just saw your post now! Ultimately, you're operating with a 4200K and 4000K bulb, which is ok for blooms. If you're noticing your foliage isn't growing as big or the plant itself isn't as large as others, I would swap out the 4200K bulb for a 5000K bulb to add more blue to your setup. The 4000K range is great for blooms but not the best for foliage.
Awesome Minh! Thanks for the this! You had mentioned a tight centers. Most of mine are happy, but my Funambule - variegated is tight. I replayed the video, but could not find where that mention was. Can you share your thoughts on that?
Thanks! Funambule is variegated and I'm seeing a majority of variegated AVs need more red light than dark green foliage AVs. I'm assuming you're growing with 6000K or 5000K lights if this is happening. My experimentation lead me to believe that tight centers aren't just due to too much Lux (total light intensity), but also too much blue and not enough red. If your other AVs are doing well, leave them alone. However, add an additional warmer bulb for your Funambule (4000K or 3000K), which should ease the tight center.
@@minhbui4215 Yep - that shelf was one of my first with the LED. Same strip exactly that you show on your video. So it as all 4 rows at 6000k. swapped out 2 of the rows for the 3000k. Be nice to see how it goes.
Those 2 rows of 3000K should solve your tightness issue. Monitor it for several weeks as it improves. If it starts to get too loose, add back in 1 row of the 6000K, but it will always require at least 1 warm strip.
What would you say is a good ratio of blue to red light in a mixed variety African violet setup? I purchased these LED tubes from amazon and I am wondering if I need to supplement with other lights or if they will provide good general use lighting. I got this spectrum because I don't care for the blurple colored lights indoors and this bulb is advertised as providing good light for all stages of growth. www.amazon.com/gp/product/B07HJVV4Z7/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
Excellent presentation. Thank you Minh.

Excellent program, you may have helped me solve an issue I'm having with some none blooming strep seedlings. Thank you for sharing your work with us.
This was super enlightening, thank you for your research!
This was fascinating and I've watched it several times. Thank you for sharing!
This was absolutely great. Thank you so much!
