8 Gram

Does exactly what is offered. Perfect size to easily place in 3.5G glass jar or foil pack. Keeps true to the description by providing the best percentage of humidity for your greens. Great product, great price. Will definitely reorder.

Pretty good last a good 2-3 months effectively

Performs as expected, can bring some life into some dried material. Individually wrapped is a plus.

I have tired several different brands of these humidity packs, including the most popular more expensive one, and they fell way below my expectations. I tried these on a whim, and it is the best impulse buy I’ve ever made. Been using the 4g & 8g packs for over a year now and this product has worked wonders. I have included a couple pictures to show just how spot on thes 2-way packs are, always within +/- 0.5% RH on average. In the picture is an 8g pack that has been in the jar since August 11th 2023 and it’s still holding steady. This is what made me jump on here and write a review about these because that’s what I was in the process of doing and noticed the dates put in the jar and the RH on every single jar was 61-62% RH and the flavor and smell are absolutely mouth watering, lol. These packs are what they say they are and do exactly what they say. Great product for the price!!!! I usually don’t really read to much into most reviews, and I think this is only like the third one I’ve ever written, the first positive one I think. Just try them out and let them convince you…

Real good moisture packs. Smaller packs than the competitors but work just as good. Would definitely purchase again.

This really didn’t work at all. I’m not sure if the pack I received was bad but I placed them in my herb 1oz bags and they have not kept things moist as they should. I used all 12 packs and none of them seems to be keeping things moist and fresh. The packs feel hard, not soft like the Boveda brand. I will be sticking with the Boveda brand moving forward.

I love the Ongrok infuser machine. I’m not a fan of these hydro packs. They seem dry out of the package… old stock, or just not that good to start with, who knows. But I’d stick to the boveda ones for now. The dimensions were not correct either…

It a good assortment

Always use these for my stash . Never fails and always humidifies like it should.....keep on smoking 😶‍🌫️

These humidity controlers are excellent, very concistant.

No noto que hidrate mis flores

Obviously very old stock. 62% humidity packs should be pliable and soft with moist salts inside. These were hard, dry and totally without any moisture despiute the double wrapping. Yes you could remoisten them yourself, but I doubt they would function correctly. Gave tthem a chance after years of using the leading brands, never again. I should have read more reviews, good ones when there's new stock, slow sales so item gets older, but no date on packs. Amazon refunded instantly. AVOID!

Dry and hard….
