General HydroponicsGLCMBX0008 Maxigro, Maxibloom, Koolbloom Combo, 2.2 Lb Fertilizer

Great trio, only used veg and bloom nutrients at the moment ans are working great ❤️ going to be using koolbloom in the next month or so.

Excellent products as always from general hydroponics. Currently feeding my deck plants weekly with Maxi Bloom at half strength and Kool Bloom at quarter strength. Blooms everywhere and even more coming in.

I use it on the garden and mix as the season progresses from growth to bloom/fruiting. plenty of info , go easy, it goes a long way. The Growth bag should be bigger, as leafy plants need it all season.Otherwise zero complaints . Just think grow should be double the size of the MaxiBloom/KoolBloom packages as they basically provide double what we needed. My solution, was get a equal sized Schultz growth fertilizer(or miracle gro) and mix it evenly with the Maxi Gro to extend it out and match coverage.So long post , hope it helps. GO EASY and get a TDS meter .(Total Dissolved solids) never go over 1500.

General Hydroponics has existed longer than many of its customers. The founder of the company created the initial products well before the average person had ever heard the term "hydroponics," let alone had even a vague idea of what it meant. This... is the dry version. Infinite shelf life (keep it DRY!). Stable. This is all you need in order to get most any kind of plant from seed to harvest. Well... You also need water, of course. And most people will want some kind of media/substrate for the plant to grow its roots into and provide support. Okay, some way of monitoring pH, and the substances to adjust same are highly recommended. You *might* end up wanting a source for extra magnesium (such as Epsom salt - which is CHEAP at any grocery store, pharmacy, et cetera, and also provides sulfur which can enhance the flavor of your produce). If you choose to not use regular municipal tap water, it is possible that you will want a source of extra calcium now and then. (If you are using tap water, and think you're looking at a Ca deficiency, there's a good chance that your plants are, instead, experiencing a lockout due to improper pH or an overabundance of another element).The above... it probably caused you to begin thinking that this whole "hydroponics" thing is hopelessly complicated, huh? Not at all. The hydroponic method has been around for a long time, in regards to the modern area (the first book I read on the subject had a copyright date of 1972!). And, if you want to stretch the definition of "hydroponics" a bit, well... think "Hanging Gardens of Babylon." Whether your source of nutrition is a sack of fish heads and the entrails of hanged criminals or a mineral-based powder - if you're basically growing in water, it's hydroponics. But this stuff doesn't smell like a dead fish. And the US criminal justice system is... woefully inadequate for our needs, lol.It's good stuff. It comes in a sack, with NO water instead of a big heavy jug that's 99+% water. I've used General Hydroponics products, on and off, since the early '80s. It was, as far as I know, the first commercially-available hydroponic nutrient brand. Its products have been used by NASA. By universities. It has the pedigree. I've tried other brands. I've found nothing better. The only thing cheaper that I've found is buying my own elemental components in bulk and making my own nutrients. Which works fine, but gets to being a PITA. I'm getting old - I just want a good product, at a good price, that I can use for every type of plant in my gardens (along with the house plants, be they flowers, cacti, etc.). No muss, no fuss, not much in the way of maintenance required - and a bountiful harvest. Have you seen all the recalls of produce due to E. coli (etc.) contamination recently? Not from my gardens, lol.Buy this product. Search for and print out something called "Mulder's Chart," which explains which elements are antagonistic (in other words, giving too much of A causes the plant to be unable to take up / use B) and synergistic (when A causes a plant to not require as much of B). Search for and print out a basic nutrient toxicity/deficiency pictorial so that you'll be able to "read" your plant's condition at a glance. But a decent digital pH meter (Milwaukee Instruments pH56 is GREAT, and has a replaceable probe), and learn how to properly condition, calibrate, store, and maintain the thing. Read a book or two (or a many web articles as you want). Decide whether you want a simple passive (non-aerated) system like a bucket full of perlite (or coco coir), or some kind of actively-aerated one. If the latter... Do you, again, want something simple that is basically a plant that has its roots constantly submerged in a big container full of nutrient solution with some kind of aeration device (such as an aquarium power head and/or an air pump and set of airstones) constantly applying oxygen to the root system? Or do you want something that's somewhat more complex? There are setups in which nutrient solution drips slowly but (more or less) constantly onto the roots. Or that supply the nutrient solution at a higher rate, but only a few to several times per day. Setups in which several plants are grown together, and nutrient solution floods the combined root zone, then is allowed to drain back into the reservoir until the next feeding. Setups in which the plants' roots grow down into a pipe or channel, which is at a slight slope, to allow nutrient solution to constantly trickle in at one end and drain or the other. There are setups that— well, you get the picture. It works indoors and out. If indoors, you'll need to provide the light (and a lot of it, compared to what you need to read a newspaper), but control the "weather" and can ensure that you are not troubled with infestations of insects, by rabbits, by deer, by the neighbors pooch that likes to mark territory, et cetera. If outdoors, the light will be free and (most days) abundant - but you'll have to deal with all the usual outdoor gardening issues, plus your plants will transpire (think: sweat) considerably more water, because that is how they self-cool on hot days. For example, an acre of corn can transpire 3,000 to 4,000 gallons of water PER DAY when the heat is on, and the average large oak tree transpires approximately 40,000 gallons of water per year (so if you live in the desert southwest, lol, don't plant one in your front yard). "Why is that relevant to me, I'm not going to grow trees, and my garden won't be that large?" Well, it's an important concept to understand, nonetheless. Because your plants, not growing in the ground, have only the water you provide. When it's really hot, your plants will use significantly more water, so you'll need to remember to keep an eye on your nutrient solution reservoir. That's true in any case, of course - but what might last a week or longer when it's cool out could be gone in a day or two when it's 93°F. (I'm going to assume you're intelligent to keep a lid on your reservoir, so no lecture about evaporation from it.) The other half of this thing is, that if your plants are suddenly using water at a much higher rate today, but are still the same size they were yesterday, then they're not going to need significantly more FOOD than they did yesterday, right? Therefore, under conditions of high temperature, you will likely find that you can/should mix your nutrient solution somewhat weaker. (Make your coffee ⅓ as strong, but drink 3X as much - and you'll still get the same amount of caffeine.)Think you could never grow plants via hydroponics, because you've never grown plants? And that you need to become some kind of expert gardener first? Hardly. In fact, it may be wiser to *begin* your gardening journey with hydroponics. Choose one of the simpler methods, of course, and don't try to grow some kind of rare oddball plant that 99 out of 100 master gardeners would end up killing within a week. But think about it: If you grow a plant in the corner of your living room, you (for the most part) won't have to worry about bugs. Or weeds. Or random munchers that would be better served as a meal than finding their own meal in your outdoor garden. And the only thing your plants will be consuming is what YOU give them. Encounter a problem? Get online and ask someone for help - and they'll ask what the plant has been fed. You'll be able to tell them exactly what that is. NO possibility that the plant is growing in something toxic, or that is so abundant in the soul that it's at a toxic level. You'll know what the pH of your nutrient solution is, because you've been monitoring (and, occasionally, adjusting) it. Oh yeah, and here's another thing: In soil, you feed your plants. Then you feed your plants. Then you feed your plants. Then there's an issue. Hmm. It must have been something you did... relatively recently. But that could be one of several things. In hydroponics, you feed your plants - and, if it causes a problem, you'll probably know 15 minutes later, lol, which generally makes troubleshooting a breeze. With the soil plant, how do you fix things? Well, after you actually figure out what caused the issue in the first place, you take steps that will be expected to counteract the issue... over time. That fix isn't instantaneous and, sometimes, the plants continue to worsen before they get better. Occasionally, they'll worsen just a little bit too much, and then you get to start all over again with new plants or seeds. How do you fix the issue in a hydroponic setup? Well, you can adjust your nutrient solution and things will probably be fine hours later. Or you can just... wait for it... drain that questionable nutrient solution and mix up a fresh batch. Overfeed plants growing in the ground? "OH, NO, what am I going to do?" Overfeed some that are growing in a bucket of nutrient solution? Drain, refill, and go make yourself a sandwich - because job done.

I was looking for an affordable dry nutrient for my grow. I rolled the dice and purchased this which is the cheapest dry nutrient I could find, I am blown away. My plants love this stuff, I can’t believe I’m using the cheapest dry nutes I could find and have had no issues! I will be sticking with this stuff for a while, unless I go up to the dry commercial bags from General Hydroponics.

So far i like this gh powder way more than the liquid. These vegging plants were on the liquid trio before switching over to the powder about a month ago. The powder is way easier to weigh and mix. Also for veg i’m just using the grow mix. It’s pretty awesome just mixing in one powder, instead of 3 liquids with the trio + calimag. A bonus of the grow powder is it is very generous in calimag which is pretty expensive to buy individually. Haven’t used the bloom nutes yet since i’m not ready to flower yet, but so far so good. PS: i’m in a state where bud is legal

Trusted easy works with all medium and provides top tier results… I know there is no good way to get through to newbs and people have to make their own mistakes but they will circle back after spending bucks on water ferts .. This line is great for tap I use 1/2 tsp per gallon veg sane in flower last 2 weeks use 1/4 tsp gallon of kool bloom then flush for a week or 2

Used this brand for years. Nice to have a bundle
