    This stuff is amazing. I’ve been a grower for almost 40 years. Grower of everything that grows. My garden is always great. But last year and this year after buying 22 lbs of this it is now awesome! My friends cant believe the size of some of the stuff in my garden. Not to mention my girls. Now last year the 2w lbs cost me 75 dollars but this year quite a bit more. It’s still worth it. Buy it.. leave advanced nutrients and fox farms where they sit

    I tried the free sample and then bought the 21lb bag. I used it for tomatoes and peppers in containers (Root Pouches) and down the tube in my Earthboxes. I have a really long growing season, and the Earthboxes need additional nutrients to keep the production up.

    Due to the ease of use, I thought the product really shined in the Earthboxes. I just filled the provided measuring scoop with MegaCrop, and dumped it in the tube and filled with water. No premixing required. I also didn’t need additional calcium nitrate.

    If there is any negative, it would be the sack the 21 pound product comes in. I live in a super humid climate so I only took out what I needed for a week and kept the sack in a cooler. For my climate, a thick foil type sack would be a big improvement; however, it wouldn’t be enough for me to not use the product.

    One of the best deals you can find for nutes. Running Megcrop, Sweet Candy, and Bud Explosion in flower, and it brings the dank!

    No doubt these nutrients are well designed and properly manufactured. I have used Advanced Nutrients for as long as they have been in business, but no longer. AN is a great product, but MEGACROP is as good and in my opinion, better. When you look at the value proposition, MEGACROP blows AN out of the marketplace.

    I have used MEGACROP on indoor and outdoor grows. There does not appear to be a weak component anywhere. Leaves are consistently colored and flowers advance to their full potential. In case anyone is curious, I have used MEGACROP with tap water and with R.O. and have seen zero difference in pH balance. As to Greenleaf’s other products, I have tested each of them on numerous grows, and as with MEGACROP, I am equally impressed with the entire suite.
