Awesome
I've been using General Hydroponics MaxiGro for several months in my hydroponic setups, and the results have been phenomenal. My plants exhibit vigorous growth, with lush, green foliage and robust root systems. The 10-5-14 nutrient ratio seems perfectly balanced for the vegetative stage, providing all the essential macro and micronutrients. Mixing the powder is straightforward—it dissolves easily in water, and the included measuring scoop ensures accurate dosing. I appreciate that it's a one-part nutrient solution, simplifying the feeding process without compromising on plant health. One thing to note is that it can lower the pH of the solution, so monitoring and adjusting pH levels might be necessary, depending on your water source. However, this is a minor consideration given the overall performance. Reddit Overall, MaxiGro has become a staple in my gardening routine. It's cost-effective, easy to use, and delivers impressive results. I highly recommend it to both novice and experienced hydroponic gardeners.

Way, WAY cheaper than iDoo liquid fertilizer and works just as good
I bought this almost two years ago, and have now used it for five plantings of my 12-pod iDoo hydroponics system. I use a ratio of one-half teaspoon of MaxiGro powder for two quarts of water. At that rate, my $15.99 pouch of MaxiGro has barely gone down! I keep it in a ziploc bag, since the seal on the MaxiGro pouch is hard to close properly. After two years, the powder is still dry and not clumped (no moisture gets in). My plant-growth results with MaxiGro have been identical to the results I got with the original iDoo liquid fertilizer, at a tiny fraction of the cost. For my first iDoo hydroponics garden planting, I used the original iDoo liquid fertilizer. But when I went to do the second planting, what was left of the iDoo liquid had clumpy black algae in it, even though I had been careful to store it in darkness (in a tightly closing metal box). Then when I checked on the price of replacement iDoo fertilizer, I couldn't believe the outrageous price -- $29 for a pair of bottles, which in my experience was only good for a single planting! So I checked around, and I am glad I found MaxiGro, because otherwise I would have given up on hydroponics.

Vigorous Growth mix is excellent nutrient for Kratky-style hydroponics
MaxiGro plant food for vigorous growth (2.2 lb) I've been using this for over a year now and love the results. I keep several 1-qt. Mason jars filled with this nutrient mix, and have had great results with kale and lettuce. Results have been so good that I won't plant either in my outdoor garden this year. Seriously, what would be the point? No bugs, no dirt, no heat issues; and the hydro results taste better than the in-dirt results. I mix one Tbs plus one tsp of nutrients to two gallons of FILTERED water in a clear plastic drinking water jug. I set the jug, covered with a towel to keep out light, on the table next to the Kratky jars. Every morning, I add enough nutrient to bring the level in each jar to the base of the seed basket. Done. The kale (both green and purple) is easily as big as anything I've grown in dirt, plus the leaves are so tender that I use them in place of lettuce for salads and sandwiches. The lettuce has a wonderful, real-lettuce flavor and the leaves are firm and strong, not the limp kind of leaves I find in the grocery store. Could not be happier with this product and will definitely reorder when needed.

INCREDIBLE, but some slight kinks to work out...
Ok, I have a lot to say about this product, let me start with the good. A lot of the reviews I saw myself when purchasing this product talked about how amazing this plant food is, and how well their plants are doing. I had very similar results. I have a hydroponics setup with 36 basil plants growing, and they have absolutely exploded! I can't pick the basil fast enough! It has grown so fast that I have to plan dinners that involve a lot of it so it doesn't go to waste! After putting this nutrient solution powder into my hydroponic system, I got it professionally tested and it contained perfect amounts true to what plants need of Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, and other macronutrients. It really couldn't be simpler and cheaper with this powder...Once you have gotten it right. Now let's get into the bad things about this product. When I first added this to my nutrient solution reservoir in my hydroponics system, I thought everything was going great (I had lettuce growing at the time). By the time the lettuce got bigger though, it started to wilt. I tested the PH of the water and realized that the nutrient solution plummetted the PH to below 4! I quickly raised the ph and found another problem after some time. The nutrient powder didn't dissolve well into the water! After months of tragic trial and error, I finally found a foolproof way to get this nutrient powder to work well. Here are some steps below: 1. Make sure you buy a PH up solution because you will definitely need to raise the PH of the nutrient solution shortly after adding the powder. 2. You may want to add a water circulator or wave machine into your nutrient solution reservoir to encourage the constant circulation of water and prevention of the build-up of the powder on the sides of the reservoir. 3. Pre-dissolve the amount of powder you will need for your system in a little bit of hot water making sure to mix WELL. this will ensure that most of what's in the powder will be dissolved before you even pour the solution into your nutrient solution reservoir. If you follow these steps as I have, I'm certain you will have a better overall experience with this product, and you will get a higher yield from your plants. This one-step nutrient powder from general hydroponics is easy and I would recommend it...If you know how to do it properly.

Super food for plants and super price
I purchased to use on my cherry tomato seedlings to give them some extra oomph in this unforgiving Arizona heat. I tested it on half of my seedlings (24) and left the other half with just water. Definitely increased leaf size as well as healthy color to the stem and leaves. It has the perfect blend of nutrients for plants in the vegetative stage, but as soon as you start seeing flowers it might be time to switch up the macros

I have tried other hydroponic fertilizers in our aeropinic towers at the university but this is by far the best! The pkanrs thrive, the pH is always perfect, and it takes up way less space than the liquid beands I was using.

Prodotto eccellente e facile da usare. Ottimo per i neofiti basta davvero aggiungere acqua ed è fatto. L'ho usato con successo per il metodo Krakty.

Der Verkäufer reagiert sofort, ist Kundenfreundlich und verschickt innerhalb eines Tages. Die Lieferzeit ist unter einer Woche. Das Produkt selbst ist natürlich Top, General Hydroponics sind Marktführer und entsprechend gut ist die Pflanzennahrung. Das Produkt ist die kosteneffizientere trockene 2-Komponenten Alternative zum flüssigen 3-Komponenten Angebot der selben Firma. (MaxiBloom) Klare Kaufempfehlung, da kann man nichts falsch machen.

This stuff is amazing. I mix it up in a watering can and feed it to my potted plants and all my stuff grows better than it ever has before.
