    • MaxiGro - A Game-Changer for My Herb Garden!
Style: MaxiGro Size: 2.2 lb
I've been using General Hydroponics MaxiGro on my indoor herb garden and the results are astonishing. My basil, parsley, and mint plants have doubled in size and the leaves are a vibrant green. It's incredibly easy to use, just mix it into the water and watch your plants flourish. I've noticed a significant difference in their overall health and vigor. If you're looking to give your plants a boost, I highly recommend trying MaxiGro. ... show more

    • Used this for Kratky method hydroponic lettuce this year and it did great.
Style: MaxiGro Size: 2.2 lb
I mixed this at 4g per gallon for Kratky method hydroponic lettuce this year and it did GREAT. Perfect growth cycle, no bitterness, and easy to mix. I tested this against FoxFarm liquid and it beat it by a long shot.

    • Goes a long way. Seems to work well.
Style: MaxiGro Size: 2.2 lb
I wanted a simple alternative to the A-B formula stuff, and this seems to fit the bill. As far as I can tell, it's done the job in my hydroponic systems. I got plenty of vegetation off both, including some pretty tasty bell peppers. I also like that I can just mix up a big batch and use it when the tanks need a refill, instead of having to measure out little drops while I'm pouring in the fresh water. What can I say? I'm lazy. ... show more

    • Economical and easy to use, effective solution
Style: MaxiGro Size: 2.2 lb
Good results, produces dark green hydroponics. Very easy to use - just add water. Very economical vs premade liquid products. Good shelf life since it's in dry form. I do believe that Masterblend produces better results but MaxiGro is a good and easier to use alternative. Includes a measuring spoon.

    • Great Hydroponics formula!
Style: MaxiGro Size: 2.2 lb
The media could not be loaded. Maxigrow has a 10-5-14 formula which is great for our Exotic Tropical Hibiscus! Tropical Hibiscus do not like a high Phosphorus NPK ratio so I ran a short trial last year with good results and now have been growing a rooted cutting of our brand new variety Qanna this fall to get a second mother plant growing faster. The results are great so far, with our Hydro Hibiscus growing at least twice as fast as our rooted cutting in soil. There is very little info online about growing Hibiscus in Hydroponics, so Im testing the limits. I started with 1 teaspoon per gallon of water, and over several months have raised the Maxigrow to 5 teaspoons per gallon of water, and will continue to raise the Maxigrow until I see any signs of over fertilizing, such as leaf tip burn, discolored leaves, etc. You can test this out on your plants as well, slowing adding more fertilizer every few weeks for your plants that have not been documented growing Hydroponically. I plan to grow more of our new varieties of Hibiscus soon to help get more mother plants growing faster for breeding and propagating! thank you for a great product! ... show more

    • The best bar none
Style: MaxiGro Size: 2.2 lb
The media could not be loaded. This is the one. Use about 1 scoop per gallon every time you water. Clearly magic when it comes to vegetative growth.

    • Vigorous Growth mix is excellent nutrient for Kratky-style hydroponics
Style: MaxiGro Size: 2.2 lb
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. ... show more

    • Works great in a pure Kratky system...
Style: MaxiGro Size: 2.2 lb
...but not as good as the usual A/B nutrients when used in a standard desktop hydro system.
