Dialed in environment and piece of mind

Absolutely love the monitor. Not only has it helped me tweak my conditions but it is also fun just being able to check in on my grow without having to actually be there.
The calendar has also helped me finally take decent notes. Great product that exceeded my expectations.

Amazing product, essential to dialing in your grow

I’ve ordered 20 pulse devices now, using in 3 different locations for almost 6 years now, from personal to commercial , I won’t grow without them. The support team they have is on point and so is their app and technology. I’d recommend to anyone just starting out or people who have been been growing for years.

Great features

I’ve had issues with keeping them connected. They are less than 5 ft apart and it’s almost as if they alternate which one will be connected. When working the devices are great for collecting data or getting alerts. Mine have had connectivity issue since the day I got them and it can be aggravating when they are both offline and I’m away, that’s the only reason for a 3 star- other wise I would have to give it a 5.

Hey Coty,

Sorry to hear about the connectivity issues. We'd be happy to look into the issues and see what we can do for you. Send our support team an email at support@pulsegrow.com

Possibly saved my home!

I have had my unit for less than 2 weeks. Last night I started getting messages from my unit that things were off. I go in my grow and power is out and my outlet smells like smoke. No real harm done, but who knows what would have happened if it would have just stayed in the wall! The plug was so hot, I burned my hand and had to get a hot pad holder to get it out.

Excellent

Set up was pretty easy and straightforward. A big plus that they include an extra long cable for flexibility and a game changer for being able to view your environment from anywhere, seems to be pretty accurate on the PPF reading. It will get you pretty close to the actual light output which in my opinion is good enough for what you get in one device.

Can’t grow without my Pulse Pro

I seriously can’t say enough great things about the pulse products. I have both the pulse one band pulse pro and could not grow efficiently without them. They are the only way to help me control the environment to achieve the best VPD. Get one of your serious about growing your best!!

First one worked fine so I bought another. It won't collect any data even though it is hooked up to wifi.
There is no customer service.
You have to send a email. That is not service. We buy this to use it not wait on a email.

Game Changer!

So, so, glad that I finally decided to get the Pulse Pro! The difference that it makes is undeniable. My current grow, with Pulse Pro is head-over-heels above my last one, without it. I am still getting acclimated to using it because the amount of actionable data can be pretty overwhelming at first, but in time it's becoming more and more intuitive. Where I once thought "crop steering" was inaccessible to me and way out of my league, I am now successfully using the Pulse Pro to greatly improve the quality of my plants. From this point on, I just can't imagine growing without it. If you are looking to improve your grow and "step-up your game", get yourself the Pulse Pro!

VPD Charts

Charts looking very good. They are a good way to familiarize for growers who doesnt understand a lot of VPD. For growers that knows about VPD and his benefits its a tool for a faster recognize of the transpiration rates of the crop.
The clients love it! in Chile we doesnt have a lot of space yet and the posters are very large for some people but always has his place in the grow building.
Thank you guys!
