Thanks, super helpful and I'll check that article out this evening. That's one negative about the new Vivosun light, it has the 25-50-75-100 settings and no in between so i have to raise intensity and distance and guess at PPFDWith or without a PAR meter, the plant will tell you...
One sign is this:
Night Owl Seeds, Creme De La Compton F3The plant has now sexed and is meandering it's way into stretch and will absolutely begin requiring more light. But it's best to add light in slow increments as to not shock or stunt her.
Or this:
Night Owl Seeds, Creme De La Compton F3Multiple Cola Tops have formed Budlets, and will be bulking in short order requiring greater light intensity.
My best suggestion is to purchase a PAR meter. The Photobio by Phantohm is an affordable option, and it is accurate.
Edit: Dutch Passion has a nice write up about light if you care to check it out..
