Measuring Plant Light

If you're like us — you want to optimize the PPFD and DLI levels for your plants for the best results in both plant growth and electricity consumption. Unfortunately, we can't see the PPFD that's striking a plant's leaf and can't calculate DLI in our head.

Instead, you'll need the help of a specialized PAR light meter that provides an accurate PPFD reading and DLI calculation. As you probably know, there are expensive ($500+) specialized meters that do the job, but there is an easier, cost-effective, and readily available solution: Our grow light meter app.
