That’s got to be like when your a kid and you wish that every bite of ice cream would be magically replaced with another.

Basically is man. I did a ton of research and was brought down to this or Jack’s I believe. This hit the mark. Also a ton simpler than liquid nutes, I have fox farms dirty dozen. I just don’t use them.probly bad by now. The Mc works so good for me. I love it, good investment.

I tried to use Alaskan fish fertilzer in my tent and it smelled like a crawdad shucking party in there! 
From then on…only used it outdoors and I love it! lol

Instead of the 2 part I might try the one part sample with the kelp stuff on my current grow. It’ll be new. But I bet the stuff will work good. At least I hope.

I plan to use the one part for my outdoor grow and just add a little bloom stuff at the end. Should be a good experiment.

I’ve been using megacrop for the past two/three , maybe x4 years and I dig it’s simplicity and it does a great job of keeping my plants healthy etc. 
.
I recommend Megacrop to anyone who is looking for a one part ( non liquid.) nutrient/s line - try this , it’s not too expensive either. 
.
Happy growing peeps’ …

For people concerned about Heavy Metals, yes obviously there is testing at many stages along the way. We have never had a problem with heavy metal issues for a few reasons
-
Hydroponic fertilizers are considered the highest grade of fertilizers, since they are refined and made in large factories. We don’t actually produce any raw materials, since those are done at multi million dollar facilities, we just purchase from the biggest and most reputable places and mix them.
-
Most arsenic and heavy metals come from dirt, soil, animal products, fish products and ground water. So the main risk for heavy metals comes from organic type fertilizers or soil/media. There is a low risk from other sources.
So, its not like you can just make Calcium Nitrate, or Potassium Nitrate if your backyard lab or something and sell hydroponic fertilizers. 100% of these ingredients are coming from large factories in Israel, Norway, China and Middle East, etc…
Also since our products are dry/powder, there is no risk for water contamination from using a bad water supply or water that isn’t filtered. So tl;dr, heavy metal not really a serious risk from powder/raw hydroponic fertilizers.

It appears I have not been manually approved because this is the result of the very last step clicking the button to complete the purchase.
- Sorry, it seems the coupon “freepromo” is not yours - it has now been removed from your order.

Step by step this is what I have done trying to get the free sample.
I go to the GreenLeaf Nutrients site and click on the 3lb bag of Mega Crop and put it in my cart. I go to the cart and enter the promo code FREEPROMO. It says that the code was approved and added to my cart which puts the bag of Kelp extract into my cart and zeroes out the cost of the 3lb bag of MC. All good up to that point. Then I fill in my mailing information and hit the Checkout button and that’s when it says the coupon code is not mine and removes it and the kelp extract from my cart leaving me with a $20 bag of MC.

Once approved like I was after I sent my email address. I created an account did the same thing. And my whole total for the purchase was removed. It will work. As long as you send them you email and confirm they have done it for you.
