That's exactly why I keep my canopy around 100000 lux. If they can get 130000 lux outdoor I don't see why they couldn't take more than the advertised 75000 lux indoor with controlled temps.
Moreover, outdoor on a bright sunny day the 130000lux isn't only at top of canopy but everywhere the sun can hit the plant.
I don't think the plants can use anything close to all the lux the sun provides, but since it's free, that's what they get. In indoor settings (from everything I've read), anything above 1000 PPFD would require additional CO2, heat, and nutrients to make it worth the electric bill.
No reason to try to match the sun if it's not actually helping the plant is there? It's just upping the costs of the grow.
But why so many people are looking for super expensive lights when cheaper ones can achieve 75000 lux as well? Also I ve seen lots of people with good lights but not using lux meter so wasting their money....
Agreed! Though there is the whole fixed vs mixed spectrum choice to consider.
I use my lux meter to compare cloudy weather to the Samsung strips. No reason to guess where they should spend the day when the meter will tell me for sure.

Definitely! I don't understand why some are trying to guess which height to place the lights when they could improve things with a cheap lux meter... Anyway thanks for the sharing!
