That looks lovely!I'll harvest this Wedding Cake tomorrow. The trichs look like big grains of sugar.
Love the purple!
You are pure Geek. I remember another member stating the same about producing your own nutrients from bulk salts. I also remember thinking you guy are like chemists.Hmmm...
@Maritimer this may be of specific interest to you since I know you're using Greenway's product too and have used some of the other cost saving hacks of mine.
Was playing with the calculator again tonight. Was looking at products like Botanicare Cal-Mag+ or Greenway Biotech's Cal-Mag+. I think we are being lied to on the label. Both products Guaranteed Minimum Analysis say they are 2% N, 3.2% Ca, 1.2% Mg, and .1% Fe. They also tell us they are derived from three ingredients, Calcium Nitrate, Magnesium Nitrate, and Iron EDTA. Here is the rub....
Calcium Nitrate is 14.5% Nitrate Nitrogen, 1% Ammoniacal Nitrogen, and 19% Calcium
Magnesium Nitrate is 11% Nitrate Nitrogen and 9.6% Magnesium
Iron EDTA is 13.2% Iron
It is IMPOSSIBLE to combine those 3 ingredients and come up with the ratios 2% N, 3.2% Ca, 1.2% Mg and .1% Fe. If you want 3.2% Ca and 1.2% Mg, you end up with 4% N. Since Greenway's product is dry salts you add to a gallon of water, lets see if they are shorting us on the Ca and Mg or underreporting the true N. Greenway's bag of Cal-Mag+ says its 2.5lbs to make 1 gal of solution. So if I target the Ca and Mg, you need 637.5 g of Calcium Nitrate, 473.2 g of Magnesium Nitrate, and 29.1 g of Iron EDTA. Add those all up and you get 2.51 lbs! So we aren't getting shorted the Calcium or Magnesium, but they are under reporting the true N by 50%.
Also did a little cost analysis. If you buy the bag of Greenway Biotech's Cal-Mag+, its $33.99. If you buy at 5lb bag of Calcium Nitrate ($27.99) a 5lb bag of Magnesium Nitrate ($34..99) and a 1lb bag of Iron EDTA ($25.99), your cost to make a batch of Cal-Mag+ is $16.84 per batch. Greenway is making an additional $17.15 per batch by prepackaging it for you. The 5lbs of Calcium Nitrate will make 3.6 batches, 5lbs of Magnesium Nitrate will make 4.8 batches, and 1lb of Iron will make 15.5 batches.
For easy reference
FN Cal-Mag Recipe
637.5g Calcium Nitrate
473.2g Magnesium Nitrate
29.1g Iron EDTA
The TRUE guaranteed analysis, 4% N, 3.2% Ca, 1.2% Mg, .1% Fe
****Additional rant****
Guaranteed Minimums on labels are just that, the Minimums that can be in the product. The true amounts may differ. Why would a company knowingly only report half the N that's in the product? My guess is that they know how conditioned many Cannabis growers are to reducing N in flower. How many times on this forum and others do you see a grower looking for a low N Cal-Mag product? Plenty! If they put the true 4% on the label, it would likely hurt sales. The only way to know exactly what you are feeding your plants is to make your own nutrients from bulk salts.
You are pure Geek.
Harvested one of the Cakes today (the one previously pictured). She did have some great color. I'll see about a picture or two when I get home.
Also did a thing while killing time at work. Bought 10 Blackberry MoonRocks (Photos) from @Expert Seedbank . Also bought some SCROG nets. Once I get the remaining 3 out of the tent I'm planning on 2 SIPs with the MoonRocks under a SCROG. Current thinking is to go the Osmocote plus supplements in flower route. I'll have several more weeks to see how that plan is working out in the other tent before making that commitment.
These two for me please!Amnesia Blackberry MoonRocks, Rainbow Kush
Everything's going my way!
I was going to vote for the SIP so, can I be VP?Looks like you'll be getting all your wishes. Since you have been the only vote, it looks like it will be the Blackberry MoonRocks and Rainbow Kush. You had also wanted to see SIPs with FN Fertilizer™ from the start. Plus I have some SCROG nets to try out.
