January 24, Sorry for the delay of the production panels; the result of the roottest will be implemented. They will be available 4 weeks from now, price will be around 200U$, powersupply included.
 January 26, 2 days ago all plants have been transplanted to the 40*60 cm box, and I switched to flowering. They'll be finished by March 29. I also modified the panels so they give 100% extra Farred and the Farreds will be switched On in all fases. I do think the lower temperature with Led's will indeed effect the nutrient transportation through the roots to the top of the plants, I hardly have to water them, therefore I will double the dosage of Bio-Bloom. I don't think it's a big risk; the 80 liters of soil will be a great buffer.
 Led roots can be totally healthy, this is taken after 10 days of vegging in Growth fase. What I've learned from this Root-Test is rather obvious; If the plants look healthy above the soil, the roots are fine.
Result of the first 6 plants with just Red and Blue, Roots are ok, above the soil the plants look pretty good as well. I do think the internodes at the stems could be a bit far apart. Please note it's hard to come to a definite conclusion with such a limited test as this.
Result of the second set of plants with just Red and Blue, Roots are also ok, plants look pretty good again, internodes possibly a bit far apart.
 Result of the plants with extra Farred,
these I like the best, the color is better, roots are ok and the plants seem to be a bit bushier with the internodes at the stems closer together. As a practical result for the panels I am building; I will use extra Farred from the start.
 Here is the result of the plants with the normal amount of Farred and CherryRed (740 nM) added, it is quite clear the plants would have preferred extra Red or Farred instead of CherryRed.
January 14, Today I started a test to see whether adding CherryRed and Farred Led light during growth fase will improve the roots. The panel in the back is left unchanged as reference, the other is divided in 2 sections, the left one with Farred and the right one with CherryRed (740 nM) as well. In a couple of weeks I will know the result and the plants will then be transferred to the usual box. The strain is PowerPlant again, I won't change that anymore. The glascontainers are darkened to prevent disturbing the roots, thanks Rick!
