I understand, what is the intended use? When is the ideal time to use it. When do you recomend useing it?
Threw veg the whole time?
Threw flower the whole time?
when do you take out of seeding and switch to veg?
So the intended use for the CREE XML2's is to add a white supplemental light to our narrow band 3w LED spectrum.
Seeds & Clones don't necessarily need deep blue or deep red light for growth, in fact too much red or blue can be potentially harmful to the the young plants. The XML2's alone provide the perfect white light for seedlings and clones. Many growers just use fluorescents for seed and clone development, because they too emit a white light.
I would switch on the VEG light after about a week to a week and a half, if you are growing Autoflowers from seed (2 weeks for photoperiod). Start high and work you way low. If it is too intense for the plant in early veg just run the VEG switch then add the XML switch for additional intensity as the plant becomes larger and more hardy.
During the vegetative state the plants will be more hardy and are able to absorb more blue and mid spectrum light. The VEG switch gives your plant the most efficient spectrum of light for that time in the plant's development cycle, which also includes UVA. Adding the XML switch will add more intensity (basically photons hitting your plant canopy), more elements for the plants to use during the photosynthesis process. While plants use mostly the bluer range of the PAR spectrum during this period, mid spectrum light and red light is still absorbed, just in smaller quantities.
Finally during BLOOM, it's about having the most intensity as possible, which we do by adding the deep reds, along with running the VEG and XML switch for the best yield and potency. Autos will start flowering automatically at around 3-4 weeks, you can also just run the VEG and BLOOM switch during early flowering then add the XML switch for more intensity as the plant gets larger and more bountiful.
Hope this helps!!!
