Top quality, low prices.
Green leaf would literally put everyone out of business if hydro shops started stocking it. It’s super cheap, lasts ages and is super accurate with their online dosage calculator, I used it years ago but ran out and couldn’t find it anywhere, no one’s even heard of it, and now I’ve found the whole line on Amazon. Winner winner chicken dinner.

Great all round nutrients
I'm new to MegaCrop but I'm pretty sure that it'll be my go to nutrient source from now on. It's not the easiest to use but after a bit of practice it's not too bad. Basically the way that the nutrients are stored in the bag is a little inconsistent. There's a mix of powder and little balls that are hard to gauge if you are trying to make small consistent batches. It's recommended that you mix 4g into a gallon of water which I didn't do to start with. I'm having much better results now that I'm following the instruction. The results are very good. Big, vibrant and bushy plants is what I now have after a sketchy start. It's also very cheap for what you get in return and can be used in almost every medium. I'm running hydro and soil plants next to each other using it and both are doing great. It's a really good product once you get the hang of it.

Amazing!
It feels like THIS is the stuff thats used through America by some of the bigger players. Great response by the plants, nice lush green growth, no tip burns; yes theres some slight residue/sediment, but i can live with that! Would definitely recommend!

Mega Crop is an outstanding all-in-one fertilizer that has completely exceeded my expectations. Whether you're growing in hydroponics or soil, this fertilizer delivers everything plants need for healthy, vigorous growth. I love that it combines essential macro and micronutrients with organic components, eliminating the need for multiple products. It's easy to mix, dissolves well in water, and provides consistent results — my plants have never looked greener, healthier, and more productive. The fact that it's a one-part formula makes feeding incredibly simple and efficient. Overall, Mega Crop is a high-quality, well-balanced nutrient solution that I highly recommend to both beginners and experienced growers alike!

This stuff is easy and does the job well . It also automatically adjusts ph to 5.8 . Perfect for my hydro setup

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.

I’ve been using a few of Greenleaf Nutrients’ products for a little while now, and I will say that they do seem to work well in the garden. The bags are a good size and a decent value considering how much fertilizer you get. So far plants seem to like this 1-part fertilizer. When switching from another nutrient program, plants seem to react positively to these new nutrients. They continued to grow well. I think it should be known that these products are made in China as stated on the bottom, typed in very small letters. This may matter to some folks, and it could possibly mean that the makers aren’t as stringent as to what goes into the recipe. Who knows what quality ingredients are in these. If you are consuming your plants in the end, you may want to be careful what you feed them. This company makes it look like it’s made in either Canada or the US, but that’s a little misleading. I actually like the bags for packaging and they haven’t leaked for me. It mixes well and creates a dark color mixed solution for your plants. It doesn’t smell or anything. So it seems to work ok, just not sure what’s in it. Not sure if I’ll continue buying their products, they should be more up front with their customers.
