Busting seeds!

30 years of growing and starting seeds has always been a challenge for me. I had some special seeds and some older less vigorous seeds and thought anything is worth it to get it to grow and did some research after sorting through alot of popular more gimmicky devices this made sense and does exactly the thing I needed sprouts seeds in that very specific atmosphere 5 out of 5 seeds started in half my normal wait time! Totally worth the money works great get the apple charger!

FlexiGerm is Amazing.

Everyone out there that reads this review. The FlexiGerm is must get product from (THE ROOT NERDS).

Really go get your own today dont hesitate (Tust me i did and i wished i never waited, so dont be like me and go get it today).

I was doing the paper towel method to germinate my seeds and the FlexiGerm blow it out the water. My tap root appeared within 24 hrs of me using the FlexiGerm with the longest root I've seen thus far in a 24 hrs time span. Not to mention that the customer service was excellent with easy and trustworthy website with fast shipping.

Great Product

Works flawlessly and completely eliminates the guess work from germinating. While the price is high if you're accustomed to free options, I've found it worth the cost in time and energy saved not having to use other methods.

SET IT & FORGET IT ( except for H2O)

My 2 Aurora+ did a lot of work last year, saved a lot of time. Quickened germination times on hot peppers, cukes, tomatoes, squash, herbs, flowers, melons. In my 2 runs so far, with next generation SPROUT, I’ve seen germination times get even faster and more consistent. Basically it’s very simple, put down a pad, throw seeds on , moisten the pad, put another pad on top, moisten that, put in the lid , plug it in . With the new design it is able to handle bigger seeds , currently I have some jackfruit seeds in there. Only thing you need to monitor is moisture level, and progress of seeds. Also has the ability to put another tray on top for another germination area or daisy chain if you have more than one device. Definitely can see the thought behind the next generational improvements, and customer service is top notch, to help you be successful. Just check out on the site the list of all varieties that have benefited from their devices.

10/10 helped germ old seeds

I was expecting all to be duds and half the pack popped.
not only do they offer a great product but their support via Instagram DM is great and they were more than willing to assist with any and all questions i threw their way.

You NEED this in your life

I’ve been growing c* for over 30 years. I’ve always had a problem popping old seeds…tried with the aurora +
Cracked all 4 old seeds in just a few days..Simply the best seed germination product EVER developed.. Anything I do, will be going through this product…Very pleased is an understatement!

SIMPLY PERFECTION

I purchased my aurora+ in beginning of March this year, first run was 12 varieties of hot peppers. Immediately saw results in under 48 hrs with tails emerging, I was amazed how germination time was increased 2x - 3x
what it usually expected. Other than making sure you keep the pads and seeds moist, the device is pretty much hands off, it just does it’s thing and very well. After first couple runs, I was so impressed, I purchased a second one, preparing for upcoming season where I live in Washington D C area.
So far I've germinated in the aurora + peppers ( hot and sweet), squash, cucumber, cantaloupe, watermelon, broccoli, bok choy, beets, turnips, and more. I haven’t found any seeds that this hasn’t done a great job with. For me it’s a quick, clean, and easy way to simplify the process and obviously speed it up, while doing multiple varieties all at one time in the same place.
I’m excited to try more and more types of seeds and see how much faster they will germinate than listed on seed package. Customer service along with tips from ROOT NERDS is just as great as their product. I have some amazing pictures from results of the aurora + , when I might have not checked on it as soon as I should have.
