OPEN TOP GROW BAGS

The PRO-MIX HP open top grow bag is the new delivery system solution for cannabis producers. With eight pre-made drip holes, a tear-off opening, and its availability in two sizes (1 ft3 and 0.5 ft3 loose-fill growing medium, equivalent to 7 and 3.5 gallons respectively), the open top grow bag solution ensures ease of use.

Its multiple openings improve aeration in the root zone for equal air distribution, increasing the breathability of the container and promoting root development. It includes mycorrhizae which enhance root growth, water and nutrient uptake, increase plant resistance to environmental stresses such as drought, compaction, salinity, low fertility, and reduce transplant shock.

INGREDIENTS

CANADIAN SPHAGNUM PEAT MOSS (65-75 %)

Sphagnum peat moss is a natural, organic partially decomposed plant material comprised mostly of Sphagnum moss. This primary resource is carefully harvested from peat bogs with specialized vacuum harvesters. Sphagnum peat moss is available in various levels of fibrosity and decomposition. Careful grading ensures that the properties of each grade are optimized for a final product that satisfies stringent quality specifications.

PERLITE — HORTICULTURAL GRADE

Perlite is an alumino-silicate ore of volcanic origin. The raw ore is crushed, graded, heat expanded and screened in various particle sizes. Perlite is a light-weight aggregate that has a high total porosity and improves both drainage and air porosity.

DOLOMITIC AND CALCITIC LIMESTONE (PH ADJUSTER)

Limestone is used to adjust a growing medium’s pH to an optimum range. It is also a source of calcium and magnesium.

WETTING AGENT

ACTIVE INGREDIENTS

BACILLUS – PTB180 Technology, Bacillus pumilus

Bacillus stimulates the plant root system by inducing the proliferation of the root hairs, which favors the absorption of the nutrients. We have selected it for its beneficial action of growth stimulation.

• Increase the number of root hairs for a better nutrient absorption

• Accelerates seed germination

• Increases plant growth

MYCORRHIZAE™ – PTB297 Technology, Glomus intraradices

Mycorrhizae are beneficial associations between a mycorrhizal fungus and roots.

Mycorrhizal spores germinate in the growing medium and produce filaments (hyphae) which will enter into root cells. This association will allow the formation of an intra and extra-radical network of filaments that will explore the soil and access more nutrients and water, and transfer them to the plant.

• Expand root system growth

• Enhance nutrient & water uptake

• Increase tolerance to stresses

• Reduce transplant shock

Not for gnawers
Size: 11.5 in, Color: Bear
I was hoping this would work for my teenage ACD and save my leather goods from being chewed on. He gnawed on it quietly I was thrilled. But I had to take it from him within a few minutes. Gnawing apparently equals chewing pieces off. Not made for chewers or gnawers. It seemed to be well made, was soft, was actually a fairly good size and didn’t get gross when it got spitty. Just didn’t work out for Captain chaos destructor of all.

It's tough!
This chew toy has held up well. Yes, the squeaker did succumb eventually. Yes, my dog was able to eventually chew pieces from it. However, it has lasted longer than any other chew toy we have purchased other than the Nylabone type. I even bought several for family members who have dogs.

A bit heavy, so mind the sizing. Good though.
My dog is a relentless chewing Jock. He's 11 lbs of Chi X and runs and chews until he's exhausted. I got the 6" for him and it's a bit heavy. He already unraveled and ate the string tape, so I braided and knotted it. He likes it when I can get him to chase it. I'd get a 4" if I were to do it again. It's a great well made product that really let's him get a good chew on.

Pup’s new favorite chew toy!
My son let one of my pups have a corn cob, which my dog enjoyed immensely. However, son got scolded as these can be very dangerous to dogs, and I disappointed my pup by taking it away. I went to Amazon to see if, by chance, a dog toy existed that was a corn cob. And there we found this- the new favorite of MANY chew toys for my medium size aggressive chewers. I bought two, one for each. They enjoyed “tug-a-war” due to the handy rope end. It squeaks. It’s strong and well made. It’s by far their favorite chew toy. I did store them in the fridge prior to giving them and pretended to eat them to make the pups think they were “real”. The package says they are dog toothbrushes, so a good benefit there as well. I’m sure we will be getting these regularly.
