How It Works

Customer Reviews

Nice product

I really like the environment control aspect, but I really wish I knew I needed to have monthly subscription to activate all the perks.

Hi Armand,

Pete here from Pulse. I'm the CTO and responsible for the product development, and wanted to give you some context about the subscription.

Infrastructure costs money to run, and a single payment for the product isn't enough to support the product forever. I want to keep Pulse running forever, and since we never sell any of our users data we need to get some other source of recurring revenue so that's why we have a subscription.

The users who pay the subscription support all of the users who don't.

We have never reduced the features (perks) we offer for free. In fact the things we offer our users for free are continuously expanded!

Here’s a list of things we’ve launched for our free users in the last year:

- Increased free data view to 3 months
- Day/night averages
- Dew point
- Variability stats
- Filters for journal
- VPD guidance
- Native apps & notifications
- Better international support with dates & times
- Low battery alerts
- Sparklines on dashboard
- Change over time details in notifications
- Probably a dozen other things i'm forgetting

All that being said, if you feel like you’re not getting your money’s worth from Pulse, we’ll extend your return window. Just contact support, and we’ll take care of you.

Great investment

I think it's great. I have Some thoughts tho. As always you should keep working to improve the journal section of the app. I would also like to seem some detailed Instructions on how to use all the features. At $500 I would like to know everything I can about it. Maybe a instructional video series.


I recently completed converting extra space in my garage into a dedicted grow room. My space is devided into two rooms about 10x10 each. I already had another brand of sensor that i used in my tent grows and was going to upgrade that system in the new space. First i looked at reviews for the latest info and came across the Pulse One review. I decided to buy this sensor instead because it has the light monitor and the vpd...something ive just learned about and want to monitor. Yesterday i started the first environmental testing and was more than pleased with the Pulse One monitor and app. I havent even customized it to any degree ( need a mentor ! ) but it has all the relevant info at touch of an icon, it doesnt get any better than that. Im using a backup monitor from a competitor as a control and the Pulse One is by far a superior product in refresh time and reporting data. The graph feature is excellent for visually oriented types like myself, who want to see comparative data at a glance. This is a great product that will make my grow life so much easier and stressfree, thanks Pulse Labs.

Great product!

Great product and can’t wait to receive my pulse pro!
