Different than the label they directed me to. And different than what's on the newest bag I've seen. They also said the website label images on the product page were the current/up to date ones. Yet they're both different label percentages. One of them is the same as your bag, but I was told the other one (on their page, the 9.5-7-1) is the current one.

What's it actually look like? I've heard that's the best way to tell. Can you take a picture?
Yea seems like they use the same bag for all sizes so could be old ones for 500g samples. I like that with the ro I use the ph comes to 5.9 to 6.1 which is perfect for coco.IMG_20191016_230611228.jpgIMG_20191016_230540287.jpg

How'd you store it?
Lots of the ingredients are hygroscopic. And which version was it?
kept it in same bag inside of an empty soil bag inside a trash bag. I figured it was normal and sucked humidity out the room. Ive been using it trying to use it up. Ive got a few shaky plants but a lot of rock stars to. I have no idea of a version. It could be old to its about a year old. Not really sure. Should I throw away?

No, don't have to toss it. Just can't go by weight anymore, go by EC/PPM now I guess.

That should be the original version. I'd measure by ec/ppm as 2com suggested. The new version is supposed to be much less hygroscopic.

I mixed a pound into RO water into a bottle and figured out how much to pour to get to 700 TDS. Then i just added 35ml per 5 gallons or whatever the batch worked out to.
I think i will do it with what i have left. About 1.5 pounds. It saves smelling that crappy powder and its easier to measure. Shake and pour in a measure cup.
And TDS measure everything to be safe. PH too. But I find 15grams per 5 gallons gets me right at 700 TDS and i like to leave it there. Bud explosion if they look like they need it.

Which version are you using? The bags that I've been pulling out of are significantly less potent than yours, unless you're measuring incorrectly. I need nearly 5 grams per gallon to equal 700ppm (1.0 EC) in my 20 gallon reservoir.

Spoon free = 2.1
Spoon unit = 2.0

Both bags read 2.0 specs.
The 2.1 has more fine white particles, as well as the bigger white chunks. More sprinkles. Lol

(I have not mixed any of the 2.1 yet.)

Those sprinkles are calcium nitrate. I'm surprised that they mix that with magnesium sulfate. It should not be mixed together and stored with magnesium sulfate. That's why everyone else separates it or only mixes it with other compounds it won't react with. If people are getting moisture into it then they'll end up with chunks of chalk. I'm not saying the overall ingredients are bad for growing. But they're pushing the limits of a one part solution.

They're already selling Bud Explosion, CalMag, and Sweet Candy, and a few other things with science fiction sounding names. They might as well package Megacrop in two parts instead of one. Calcium nitrate and magnesium sulfate hanging out together is a bad idea. The chelated iron and zinc have issues with it as well. If you get moisture into the mix even from high humidity it can get messed up. I wouldn't buy a large bag unless you could make sure it was in an airtight container.


Calcium nitrate I have no problem mixing it separately.

The FloraNova line by General Hydroponics is also a 1-bottle product (although different bottles for veg and flower)
How do they manage to keep calcium nitrates and magnesium sulfate separated?

That stuff is so thick I think it could be mechanically separate.

Getting everything into one easy to use product appears to be the only secret sauce in the industry. DynaGro manages to do it without having a thick suspension but I think that is what limits them to weird NPK and makes the product prone to freezing/precipitation.

Its working perfectly for me .I wish they keep it as it is no to 2 part it work 10 time better then other brand so cheap to" i dont care i love it ".

You're correct. I actually have a bottle of the FloraNova veg I got my lady for her houseplants so she doesn't have to mix my dry powders. Looking at the label they do have calcium nitrate and magnesium sulfate in the same bottle. I think the way they get around it is due to the concentration.


Calcium and magnesium fertilizers typically can not be mixed with phosphate and sulfate fertilizers while concentrated. A solid precipitate will form in the bottom of the stock tank if the fertilizers are not compatible. Once the individual fertilizers are diluted to their final concentration, then all fertilizers are compatible and thus can be mixed together.


Sulfate. Injecting a fertilizer that contains sulfate into irrigation water that has a calcium concentration of more than 2 to 3 meq/l, may cause calcium sulfate (known as gypsum) to precipitate.
