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!

I have used this on both orchids and cannabis to great success. You’ll get a lot of growth using this fertilizer, at all stages of development. Burn resistance will depend on what water you’re starting with. I only use reverse osmosis, so I rarely ever experience fertilizer burn. If you use municipal water, start with HALF the recommended dose. Then you can experiment from there. Good luck!

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.
