3 days on jack's 5-12-26 and the plants are loving it! Bye bye General Hydroponics forever

This is the best Kelp product I've used, and I've tried many:

CleanKelp | Organic

The secret of the sea. Bloom City’s CleanKelp formulation contains seven species of wild harvested sea plants that are loaded with vitamins, minerals, and naturally occurring plant growth nutrients. Improves root and stem growth and relieves heat and drought stress to ensure plants grow...

I've been using this for fulvic for a while, and been quite happy with it:

Organic Fulvic Acid Complex for Growers

Mr. Fulvic is an organic amendment for plant growth that increases nutrient absorption and creates healthier and stronger plants.

www.mrfulvic.com

I love Mr. Fulvic too. For kelp, I went through the heavy metal database and pretty much tried every product that had no detectable heavy metals. I never tried the CleanKelp, just because their company wasn't listed in the database, but they sent me documentation from their end. After trying a bunch of them, I ended up really liking the Age Old Kelp-it's thick, potent, and reeks of kelp. I'll give CleanKelp a try next time. For Amino Acids, any of the 14-0-0 soy hydrolysate products are most likely using the same stuff. Down to Earth Agmino is a good example. I've totally replaced Fish Hydrolysate with it indoors and in teas, it really does feed the soil like nothing else.

460w qb:
Lux @12" 32,767
Lux @ 24" 32,767
Lux @ 36" 21,577

I was wondering why I got the same lux reading at 12" and 24". The stupid lux app only goes up to 32,767. When I tried to get a lux reading on the 660w boards it maxed at 32,767. Looks like I need to order a lux meter

Copy that, thank you I will check out the calculator and see what it says. My tap water is kind of horrible like 300ppm but I can get 27ppm water out of the spring on the side of the road if needed and was using that till I started using 19-4-23 tap water blend but almost out of that and wanted to give something else a try.

I'm in the same boat. My app doesn't seem accurate at all and I'd LOVE to know these things.

Same here.
Got mine from Amazon $30 after watching this from Migrow...

My 220w board reads..
12"- 45000
24"- 18000
36"- 8000

The reason I like the CleanKelp product is that it really is clean. It's the first kelp product I've used which isn't black There are no particulates which settle out or anything like that, and it never clogs emitters. When I first came across the product on the internet, I wasn't sure if it would live up to it's claims, but a gallon bottle is cheap enough, so decided to give it a try. Love the stuff. I need to order a fresh gallon soon. They also use multiple species of kelp in their product.

I believe that has to do with the camera sensor on your phone. Some sensors will go higher than others. I have the same issue with my phone.

lol. that's why i stopped using kelp this run. i wiped the bottom of my res and it was completely black from the kelp i was using.

maybe i'll give that brand a shot.

this mr fulvic mixes up nice by the way. 1mL per gallon is crazy cheap for it too.

Yeah, I hate that too. I think you will be real happy if you end up trying CleanKelp.

If I may ask what is the dosage you use of mega crop for seedlings and clones and on up through veg? I recently got the mega crop but haven’t started using it yet as I still have a bunch of others to use up before switching over. I got the mega crop 2 part with epsom. Also do you use anything with the mega crop? Thank you

Rurumo had some good advice. As for me, I most often just use cheap bargain fert for my young seedlings/cuttings at really low EC (in Pro-Mix) so I can't offer you much advice there. When they get older, I usually use Mega Crop at around the typical 2:3 ratio, with 2 parts calcium nitrate to 3 parts "Mega Crop A", maxing out at about 1.4 EC. It's already fairly high in magnesium sulfate, so if you do want to add the Epsom, go lightly at first. I have done it at .5 gram/gallon to 1 gram/gallon. I don't think it's needed though, tbh... I'm just a fan of super dark green leaves.

You mentioned that your water ppm is 300. Do you know what percentage of that is calcium? Because if that's mostly calcium, you might find good results with just using the Mega Crop A all by itself, without adding any calcium nitrate at all. The amount of nitrogen in the Mega Crop A is adequate for most situations (in Pro-Mix, with average light conditions), so the addition of calcium nitrate is mostly for the presence of the calcium. If you start getting spots or limp leaves, you could always add it back in. This advice might not apply to coco, DWC, etc...

If all of this is too much to bother, just try using it the same way that you would use your Jack's.

 

[jonnynobody]

@rkymtnman how's the flower flavor in DWC? I've only ever ran soil and hempy buckets. I've got 4 plants going in coco to see how the flavor and growth rate turns out. So far they're looking fantastic. Giving another crack a soil this time too. Dam mites got my last soil lady.

I don’t know exactly how much is calcium but I believe it’s pretty high in calcium because we get a lot of calcium scale in the hot water heater and faucets I have to clean them with CLR fairly often so I will try a separate clone in coco with just part A and see how it reacts to it.

 

[rkymtnman]

how's the flower flavor in DWC?

i would say it depends on strain and what additives you use. i love Sulfur. also think Kelp helps as well. use Si and Fulvic but not sure how much that affects smell and taste.

That sounds like a good experiment. It could end up saving you some money if it works, plus too much calcium can be antagonistic to many other elements.

I have 4 clones in Coco 2-OG Gelatos & 2-Gold Leaf and all 4 are same age and from same mothers so I will do 1 of each strain with just mega crop A and the others with both and see the difference between them. Hopefully I can get away with just the part A and save a bunch of cabbage each grow

Calcium nitrate is cheap, bro.

Yeah 50 bucks for 25lbs on Amazon for the mega crop Calnit but I’m sure there is other options out there
