You mean the stuff that grows/collects on the side of the res?
Ive been boiling and reusing my hydroton

The two part does not appear to have the chitosan or the kelp. This might be one possibility why the color is lighter. Personally, I am quite happy not to have either of those two ingredients. Kelp lovers please don't hate me.

I was reading the list of ingredients again for the "part A" that contains all of the other ingredients besides the calcium nitrate and I noticed that the label lists "amino chelated calcium" This seems like a mistake, which brings me to my point: What is it with this company and their ridiculous labeling issues? There have been several complaints about people getting product with the wrong labels, or that the EC of listed mix ratios does not match the actual EC that people are testing, or that their cost analysis chart is inaccurate. I am not dissing the product. It's a great product, but it would be so much more professional if they paid more attention to these sorts of things. Oh, and there are elementary school-level grammatical errors on the page too. I swear, if I didn't like this stuff so much...

Just got some of the new "Part A" in the mail today. It does indeed list "amino acid chelated calcium" as one of the ingredients on the sack. If this is true, then they should list calcium content in the G.M.A so that people can accurately calculate feed schedules. If this is a mistake, then get this off the label and quit confusing people!
Some other observations:
- In true Mega Crop fashion, the stuff stinks.... horribly. It smells like some sort of animal feces that they use on the local cranberry farm. Fortunately the smell dissipates readily when mixed into water.
- Very uniform powder that dissolves quickly. There is a small amount of a very fine sediment left over which is so fine that when I pressed my finger into it at the bottom of the jug, it did not have a noticeable texture. It seemed almost like a tiny little blob of toothpaste or something. This little tiny blob showed up every time I mixed a batch and at every concentration. The blob finally completely dissolved after about 30 minutes of just sitting there. I wouldn't classify it as much of a concern.
- The mixed product is quite clear. Maybe just a little "foggy"-looking. I like this.
- There is the odd solid chunk of something in the mix. About the size of a pebble, and of a dark color. The frequency of them would be maybe one of these "pebbles" per every few cups of powder. I tested one under the tap water and it dissolved completely over the course of about a minute.
The smell on my fingers from it was very metallic; similar to iron. Possible concern for very small batch mixers.
- NO DUST! Not like my previous versions of regular Mega Crop. Even when I agitated it on purpose there was no noticeable dust at all.
- Slightly acidic, but not bad. Nothing like Maxibloom. Tap water with a ph of 6.8 became ph6.0 @ EC .6 and ph5.8 @ EC 1.2 Maybe the silica?
- Has a nice coincidence of .1ml/ltr ( I prefer to go by volume, not weight) being approximately equal to .1EC. (municipal tap water of about 20ppm) This makes it easy to quickly figure out various mix values. I tested this a few different times in order to make sure that it was consistent.
- Much higher in magnesium and sulfur than one part Mega Crop.
Overall, looking forward to giving it a try.

I'm interested in any feedback you have while trying out the MC two part.
Thanks.
Great piece of feedback there!

I sold a bit smalller amounts so just wating for feed back on the forums. One of my customers that loved the V2 picked up 15 x10KG bags so hope it does the same lol.

Will do. Just to be clear though, I am only using the Part A and not the Part B, which is calcium nitrate. I use Botanicare Kind Base as my source of Calcium Nitrate. Shouldn't be much different though...
Just had a peek at that "Base", interesting. It's like a liquid calnit. Seems a bit low in calcium though? Cool.
Thanks.

The kind...
4-0-0-5ca
Per ml. Per gallon.
N. 10.6ppm
Ca. 13.2ppm
Jacks calnit....
15.5-0-0-18ca
N. 41
Ca. 48
Per Gram.
5.0% Ca, versus 18.x% Ca (Jacks)? (The actual ratios of Ca to N seem close, though, I guess. Unless I messed up the zero effort math).
My mistake..
You calculated (elemental) ppm?

This is the calculator dealio I use.

Enter 1 for Mixing units.
But..... I found entering 10 for Mixing units gives a little more accuracy. Just gotta be careful with decimal.

Ok, yea. I basically did the opposite of this to check what I initially did (compare ratio of Ca to N for both). Either way works.
Cool.

Thanks for that. I think will copy and paste it somewhere.
