Gotcha! WhisperGrow was our April Fool's Joke

We don’t whisper affirmations to plants, however, we are a team of engineers, data scientists, and plant lovers who take greenhouse optimization very seriously, but we don’t take ourselves too seriously. While the "Daily Affirmations" module won't be appearing in your Source dashboard anytime soon, the inspiration behind the joke is rooted in fascinating, peer-reviewed science.

THE SCIENCE OF SOUND

It turns out, your plants might actually be music fans. The research we cited throughout this campaign is 100% real. Plant Acoustic Frequency Technology (PAFT) has been studied for decades. Controlled greenhouse studies have shown that specific acoustic stimulation, at the right frequency and decibel level, can significantly impact plant physiology. The real-world results from PAFT studies:

+37%

yield increase in cucumbers

+30%

yield increase in peppers

+13%

yield increase in tomatoes

Our gift to you:

We may not be launching an AI-voice module, but we are an office full of music lovers. To celebrate the science of sound, our team has curated a special Spotify playlist.

These tracks were selected because they sit within the frequency ranges (0.1–4 kHz) shown in research to benefit plant growth and cellular activity. Whether it helps your crops or just your morning rounds in the greenhouse, we hope you enjoy it.

Listen on Spotify

Something Big is ACTUALLY Coming...

We’ve been working on something a lot more powerful than a playlist. If you’re a pepper grower looking for precision, predictability, and an edge that doesn't require a microphone, stay tuned.

Launching April 7, 2026.
