A lot of YouTubers recommended this so I thought I'd give it a try. When it arrived, I was quite surprised how small the packages were, but it matched the description so that's on me. That said, a little goes a long way. I've used this in both a system with aeration and without (Kratky method) and it worked perfectly in both cases. Here's what I've grown with it: - Basil indoors with natural light - Basil indoors with artificial light - 2 kinds of Lettuce indoors with artificial lights - Spinach indoors with artificial lights - 2 types of tomatoes outdoors with natural light. The Plant growth with this fertilizer and the hydroponic method was far superior to similar plants planted in dirt. The plants that had aeration did better the ones in using the Kratky method. I don't think I'll try tomatoes again simply because they take so much solution throughout the year vs. the ones I planted in self watering soil containers. Overall, 5 stars. Works as well as the YouTubers claimed it would and lasts a long time.

Arrived as promised. It was boxed well. The bags are sturdy. I will buy again.

I wanted to give Aerogarden users hope in this fertilizer now that the Aerogarden fertilizer is no longer available. I am posting before and after photos from the day that I started using this three part Master lend. The photos taken today are one month and four days later, using only a pure solution of Materblend. I top off my eight 12 pod gardens and one 9 pod garden by using 2 1/2 gallons a day of Masterblend to top off all nine gardens. I weigh 6 grams of the Masterblend, 3 grams of the Epsom Salt, and 6 grams of the Calcium Nitrate into 2 1/2 gallons of water,in this exact order, per instructions, and stirring each one in until dissolved before adding the second and third component. Then, pour it straight into your garden. I fill the entire garden tray with this Masterblend solution instead of using two syringes of fertilizer like you do with the Aerogarden brand fertilizer. My plants in these photos were planted on July 30th 2025. These are indeterminate orange tomatoes. The before photos were taken January 17, 2926 using Aerogarden fertilizer. They had lots of blooms, but very little foliage, and the foliage was yellow and turning brown. The after photos are a month and four days later, taken today, and I am having to trim 50% of the foliage off of the plant every two weeks because they have grown so much with the Master blend. They are green and healthy. I linked to this review from my previous purchases link, so this seller and produce are the exact ones that I am using. You can clearly see that I have had AMAZING results using this Masterblend 4-18-38 fertilizer used full strength in my Aerogardens.

Great stuff but I still feel its pricey

The stuff makes my hyperponics in my garden grow excellent Love working with it The neighbors don't know how my vegetable plants get so big with so many tomatoes and stuff on it using beta buckets

I had essential oils to these salts for hot bath for RLS. Great combination.

The plants are still alive and growing
