    • Excellent product and great customer support
Size: 3lb (1.36kg)
I have used the one-part Mega Crop for a few years now, both the old and new formulas, and have had great success with it. I recently bought a new bag to re-stock. When it arrived I saw there were some hard clumps in the bag, which isn't normal. I emailed Greenleaf support that evening describing the issue and sent a pic, and they responded within an hour. They shipped a new bag out to me the next day, no questions asked. I appreciate businesses, like Greenleaf, who stand behind their product. And their products are really good. I highly recommend them. ... show more

    • Works amazing, and the price is great
Very easy to use, with my RO water the ph has stayed between 5.89 and 6.28 at all strengths from 1\8 to the full 6 grams in flower. This is my first grow since getting my script and it has been amazing. Harvest first plant in two days. I did what most people say not to and started multiple strains and only have an issue with one plant having a calmag problem which I blame on the pheno as I have two of the same ww and no other plant has shown the same problem. This appears to work amazingly as a stand alone with the majority of plants but I would recommend extra calmag on hand, a little extra silica never hurts either. This is by far cheaper than any premixed nutes and you can try a sample off their site first and just pay shipping (which is what I did.). The sample is plenty for a smaller run, I have 5 in flower and four more in veg and have about 3/4 of the sample left still...I can only imagine how long this 20 plus lb will last. Only thing I don't like is the nitrogen balls draw in moisture and start sticking together. I have it in an air tight container with silica packs and it still happens so I would recommend pulling out a smaller amount from the large bag and sealing the rest in a food grade bucket with silica packs, only open to refill smaller container and leave sealed the rest of the time. Hopefully that will avoid so much moisture. I read they are changing up their recipe so perhaps moisture and calmag will not be an issue anymore, who knows. Either way it is affordable, easy to use, and works amazing. If your new to growing research everything first (I spent 4 months scouring the net before ever making a purchase.)from strains, breeders, electrical requirements, nutrients, deficiencies, temperatures, lighting, fans, ducting, water ph, Rh, lst, hst, monster cropping, mainlining, reverse osmosis systems etc and you can avoid the majority of newb problems I have read about. I have a lot to learn still but didn't lose any plants and have a MUCH larger yield than I expected for a first run. ... show more

    • Great product
I’ve been using their products for years now and totally pleased with the results. Took me years of trying different nutes to find this one I’m sticking with. I also use their sweet candy and bud explosion also.

    • I Love this plant nutrient (and so do my plants)!
Size: 3lb (1.36kg)
Using this plant food/ nutrient makes things so much easier! I love that it is not smelly, it is easy to measure how much to use, and it gives my plants everything they need to grow big and beautiful! I man's its super simple, if the plant is yellowing ,give it more. If the plant is getting dry tips on the leaves ,use less. I have never had such an easy time feeding my plants nor have I had such great results! Thank you for this awesome product! ... show more

    • This stuff was working great
Size: 3lb (1.36kg)
Really liked the results I was seeing the 4 times I used it went to use it the 5th time and apparently the corner of the bag was not sealed all the way and it turned into a bag of cement and was un usable it was stored on the roofed porch inside a deck box so careful how you store it because if there is any moisture in the air it will be rendered useless.. ... show more

Good spectrum of nutrients plants love. A little goes a long way. Used a coffee grinder to break it up into a fine powder then added to reservoir with a little extra cal mag. Ladies were praying to the light the whole grow. Later added their Bud Explosion as well. Who wants to be a mad scientist when mixing nutrients right? This is simple and effective. Grabbed an extra bag too so I’m good for years! The Maui Wowie here tells the tale. ... show more

    • The best
Size: 3lb (1.36kg)
I’ve been indoor growing for 10 yrs with monthly harvest. I tried a lot of different nuts. When I found this and first mix seen what PH did…. I knew I had found what I had been looking for. This really works from seedlings to smoking. I use cal-mag also. I had it already so not even sure I need it. I see main complaint here is way it mixes with water. I grow in soil and have always used a drill with a cement paddle wheel for mixing my nuts….. I have no problems with mixing. ... show more
