Way off!

Using a spider farmer g5000 grow light sitting at 24” above canopy pulling 200 watts at 40% in 4th week after seed popped soil surface. Leaves are praying but level with eye. This app says I’m at 70 ppfd. Wouldn’t suggest this app to nobody. Doesn’t even reach suggested ppfd sitting right under light at 100%. You use this and you’ll fry your plants crispy for sure.

Excellent light measure

Very easy to use and excellent light meter. It is also reasonably accurate and no big fluctuations when you hold your phone steadily in front or under the source as the case may be. Works for LED, incandescent, natural sun etc. No required diffuser attachments. No muss no fuss. Totally decent application!
