Athena Stack is a natural plant stimulant made from an extract of kelp and other plants. Our proprietary cold-enzymatic extraction process preserves the natural plant hormones, vitamins, and amino acids.
The secondary metabolites in Stack encourage increased lateral branching, tighter nodes, faster bud set and increased vigor during transition. Stack gives the plant tools to reach its full genetic potential.
As a foliar spray, bioavailable micronutrients are quickly absorbed into the plant. Stack is an excellent addition to any feeding protocol. It will not create antagonism when used with other products.
Product Features
Irrigation - Compatible with most dosing and irrigation systems. May cause biofilm accumulation in systems without proper cleaning protocols. Use Athena Cleanse to reduce buildup and system clogging.
Solubility - 100% soluble, no residue, will not clog emitters.
Stability - Once mixed, pH will remain stable in solution.
Compatibility - May be mixed in the same spray with Athena IPM.
Best Practices
| Mixing | Stack contains organic ingredients and may separate in storage. Shake well before use. |
| Measuring | Carefully measure using clean instruments. Never put anything into the bottle. |
| Water | Compatible with all water sources. |
| pH Range | 5.6 - 6.2 |
| pH Adjustment | Use Athena Balance to buffer water or adjust to desired pH after mixing. |
| Storage | Store closed in original packaging at a temperature between 7° C and 29° C. |

Not indestructible, but the best I’ve found
Color: Onyx Black - Most Durable, Color: Onyx Black - Most Durable
This thing is unexpectedly heavy for its size. My 18 month old Giant Schnauzer is obsessed with fetch but destroys every ball she gets. The other brands marketed for extreme chewers tend to last about a day or two before they’re totally shredded. She’s had this one for about 2 weeks and it’s looking rough, but still holding together for the most part. I appreciate that as it comes apart it does so in little pieces rather than large chunks. While it’s far from indestructible, it’s the strongest I’ve found so far.

Great product!
Color: Onyx Black - Most Durable
Great product! Quickly became my Pit Princess's favorite toy! The size, weight, and material is perfect for a big dog. Now we have fetch ball that has proven itself to be worthy!

Yes!
Size: Medium
Durable. Squeak doesn't last forever with my aggressive chewers but crinkle does. Best balls.

Balls

My dog loves chasing these balls. He seems to love the squeak! They fit the chuck it stick perfectly, and are great replacements for the originals that came with the stick.
