I always loved hoe Thrive made the plants stand up and salute. Here are my spring seedlings doing YOGA after a dose (or two ) of TINY amounts of Holy Cow in the last week. OMG or Holy Cow is right!!! Get some and share the love with your girls.

I've had great success spraying over freshly laid sod when doing a lawn renovation to help it root and grow vigorously.

Worst smelling liquid I have ever smelled and I have changed baby diapers! I went light on the amount used and still have seen my plants take off like crazy. Make sure you shake well before using as it separates fairly quickly. Thanks again to BAS for their amazing products. 5 stars!!

Great stuff I'm using 2 Oz per 5 gallon of water along with build a bloom powder. We tried 6 Oz per 5 gal was too much. Low dose seems perfect. Happy plants explosive growth. I also top dressed a.week before flower cycle. I recommend to my friends that grow. Thanks to Eric he recommended it , he is very knowledgeable I learn something every time I order.

Young plants seem very happy with this new addition. It does smell like a cattle truck when you open it.

I used from early Vegas to mid flower this run and have seen it do wonders with additional nutrients. A little goes a long way.

I have never had a product have such an impact on my plants. All fan leaves have been praying the entire grow and the plant has shown more vigor. Will definitely keep using this product!

I'm going to make this short and to the point... Holy Cow is very effective and every type of plant from seedlings to mature plants absolutely love it. I use Holy Cow and Comfrey FPE from seed to transition and then switch to Yah-Whey and Watermelon and Comfrey FPE's and plants absolutely love it. Leaves start to reach for the sky after a single application. Highly recommend!

I can't say enough about all the products yall carry. I had what looked like a calcium issue so I bought some gypsum was told the Yah-Whey would break the gypsum down to make it plant available. Went by all the directions on dosage and the problem is still there on some of the plants but the flowers are really stacking so all in all really good results so far. First run in this soil so I think in time it will only get better. Love ❤️ using all the products. Tks for all you do.
