Cow Cal 24 - Food Grade Calcium + Phosphorus Reviews

Loving the results I’m seeing ! For a while I was just using fertilizers in my soil and just shooting in the dark if that makes sense but now I’m able to input these ingredients, see how my plants react to it and know exactly what they want. Thanks for all the videos you guys are doing keep it up!

This was offered for sale by BuildASoil in the middle of my current grow, girls already flowering. Was using Amino Cal Boost seedling thru flowering to give them calcium, but tis product also has phosphorus, plus more calcium. Added to BuildABloom in water, my buds fattened up faster than I expected. Will start usingthis on the next grow as soon as signs of flowering show.

I’ve been looking for something to use in top watering that has a decent amount of P in it and this happens to fit the bill perfectly. The Ca content is off the charts, the plants love this stuff during flowering but also works great in veg if you’re looking for something with some P and Ca that’s water soluble.

Growing in 5 gallon pots, they eat through calcium fast! Especially running organic alive products ( heavily ). Since organic alive has been out of their Cal 10, I needed an alternative. Cow Cal was the product my plants needed ! Went from calcium deficiency, back the praying within a day . Product works fast !, not sure as fast as Cal10. I've been using 1/4 tsp (0.7g) per liter of water. Thanks for this product , and at an affordable cost ! ( Here's my flower line up , using homemade 3.0 soil, top dressed with craft blend . )

This stuff works great. I was looking for a safe source of calcium and plants seem to respond very well to it. My last run i was noticing some little rust spots on the leaves in flower that I figured was probably calcium deficiency and have not had any this time around.

I love this stuff. I use a little less then 1 tsp per gallon once a week. I don’t even do full organic but this is one of my favorites all around

Haven't tried it yet but I am excited to add it to my collection. I don't think I've ever had bad results from bas

Good stuff for the money, seems to be helping my ladies along nicely!

Loving using this for top dressing

One of my go to’s great product, great company highly recommended, AAAA+

I'm not sure on when to use it. Or how,

Great addition to my grow. I would recommend this product.

cool this one is kind of all inclusive calcium product. always good to have multiple forms of it.

So far so gud , plants perk up more after a dose, week 3 🙏

My garden seems to love the Cow Cal!

Good products seems to work right away and great product

I've been growing for about 2 years. My plants have always had purple / red leaf stems. Never realized this was a sign that they were in need or a state of stress. Until ... I was watching a bas vid and close ups of the girls had all green leaf stems.. this was at around the same time mine would be turning color. After a deep dive into what this could mean I decided to give this product a whirl. I dont like adding things to a grow that is going great but I also like to understand things.. its only been 24+hr since using this product.. I watered it in. Not foliar.. Its crazy that I can literally see reteaction of the red. Idk if it is a calcium issue or a Phosphorus issue . I do know the girls are praying and the red is going away.. I would like to see directions on the package ..also I'd like to see a product highlight video on it.. I know one was made because that's where I found this product.. its not in the product highlight reel on YouTube though and would have liked to watch it again to reference

Ive used it for about 4 weeks now, mixing it with my ro water, didnt make the ph jump, plants responded within two days it was obvious the plants loved it, seemingly a great product, ive been using roots organic liquid cal mag with sulfur, i prefer cow cal

I feel confident with this stuff especially after advice from the team

This is a great fast acting product. Great for calcium deficiencies in flower.

I like it better then cal mag Plants are doing better with it

Grew my best plant to date. Helped solve some past issues

Nice dense buds!! Definitely a stronger plant!

just what the doctor ordered saw a change in 2 days after using

Amazing plants responding really quickly love it

I have Grow-Cal and Oyster Shell Flour and want sure if Cow Cal 24 would make a difference or is I needed it but pulled the trigger and ordered it and started giving it to PHOTOS and AUTOS in light mix soil and 2nd cycle 3.0 soil to plants 2 weeks old and transitioning to bloom so during the stretch and I noticed a more vigorous growth and slightly larger plants then the ones that didn't get any cow cal. I'm still in the testing stage trying at different stages but so far I'm impressed. Another thing I noticed was when I add to my feeding water the Yah-Whey, FPE Comfrey, Pumpkin, Watermelon, Alfalfa and some of my own mixes It usually lowers that fluid pH really low at the times below 5.0 which is very acidic but when I also add Cow Cal 24 it raises that fluid pH right around 6.0 to 6.5 depending on any other inputs I add but that makes it better for plant absorption in my opinion. I mean I know Jeremy and many other folks don't check and/or adjust their feeding water pH prior to watering after mixing everything together but personally I like to adjust my pH to about 6.5 every single watering to avoid having to deal with soil pH fluctuations out of range fluctuations that is because eventually the soil pH will drift if you keep feeding it 5.0 pH solutions with every watering. That being said, I don't mind checking and adjusting my pH with every watering to provide optimal conditions throughout every single step of the grow process. Cow Cal 24 dissolves in water very easily and I've been feeding it at 5g x gallon of water once a week until the end of stretch so around 4th week of flower. Try it and see for yourself

I used this since week 2 and it’s see stronger and thicker stems. I have only been soil drenching every week.

New product. Always cutting edge!!!

Like all the rest of BAS, a must have.

I had major nutrient lock and cowcal helped almost immediately. Used with yah whey for super results very quickly.

Girls loved the new fertilizer addition. Better results that expected. Highly recommended as soil drench @ 1/2 tsp/gal weekly.

Plants really responded well with this product will be buying more!

Another great product from BuildaSoil.

First time testing cow cal in combination with thrive probiotic. My trees are thriving.

I added Cow Cal 24 at the beginning of flower and my plants really took off

Need better packaging, Cow Cal bag broke open due to other heavy product in same box.
