This hefty sprayer holds up to three gallons of water, plant food, insecticide, or weed killer in the translucent plastic tank. The 4" diameter opening allows the tank to fill quickly, while the included fine mesh filter prevents liquids from clogging. A dual head nozzle can also angle forward or backward, offering the maximum amount of coverage for your plants. For more versatility, the red cap in the middle can be placed on one of the nozzle heads for a smaller coverage area. The comfortable gray plastic handle depresses easily, for quick work in watering your plants, terminating weeds, cleaning lawn furniture, or eradicating pesky insects. The included gray strap connects to the top and base of the sprayer and is adjustable on both sides for a comfortable pack. The sturdy pumping arm can be used right- or left-handed simply by moving the straps on the pack. Piston pumping action from the arm allows for continuous spraying. Some assembly required.

Grodan introduces Agro-Wool Absorbent Granulate, a new domestic rockwool flock. Agro-Wool is a high-quality horticultural medium. Tests show that at initial soaking, the pH rise in Agro-Wool is significantly less than with other horticultural wool. Agro-Wool is also easier to work with when dry and when being mixed with other media.

The Grodan branded absorbent and repellent granulates (45 lbs. bags) made at the Grodan factories in Europe is still available, giving your customers a choice.

The renewed plugs result in a maximum number of useable and homogeneous seedlings. Both form and strength have been greatly improved for good machine and manual processing. Whether sowing or transplanting, the new plug is the solution to achieving a homogeneous sowing result.

• Improved homogeneity
• Optimum robustness and flexibility
• Ideal air/water balance
• Consistent shape of the seed hole
• Identically shaped plugs
• Root development through the entire plug

BIG MAMA is the largest block ever produced by Grodan. It is 8 square and contains over twice the amount of wool as the popular Hugo block. This block is big enough to grow a large plant for its entire life! When your plant outgrows its current block just place it on top of Big Mama. BIG MAMA is solid wool and does not have a precut hole thus making it suitable to hold any size smaller block on top (even a Hugo)."

Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs. Where other rockwool brand manufacturers cut all sizes from one batch of wool, Grodan is unique by making different types of fibers. The purpose is to support the requirement of the plant in the different plant stages. Grodan has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth. Grodan comes in graduated sizes. Seedlings started in cubes are easily transferred to blocks and then onto slabs, if desired. Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums.

Grodan Blocks -Grodan Delta blocks are the most uniform blocks available on the market. They feature improved grooves at the base to promote better drainage. They are available in a large assortment of sizes and configurations to suit all types of plants. These growing blocks are used for direct sowing or "blocking on" of Macro and Multiblock raised plants. AO 36/40 plugs fit well into the hole sizes provided by the blocks. The blocks can then be placed on top of a slab to provide for a larger growing volume. Hugo is the largest of the growing blocks. It provides enough growing volume to support a larger plant, so it does not need to be placed on top of a slab.

Flexible cord sets are one of the most common, yet dangerous, products in use today. Too often they can lead to safety and fire risks because of overloading, poor connections, frayed conductors, load device failure, etc.

When the ‘Chameleon' detects excess heat (110+F), it changes colors from green to orange. The color-change is a visual warning that the electric cord is potentially HOT and hazardous.

‘Chameleon' Clips and Wraps easily to:
• Appliance cord sets
• Workshop power tool cords
• Extension and power cord sets
• Portable heaters and generator cables
• Computers, office machines, cord sets, etc.

Pack includes:

• 2 round clips
• 2 flat clips
• 2 chameleons

Grodan Slabs -The final stage of planting with growing blocks are the Grodan slabs. These slabs come in clearly marked UV resistant poly sleeves for ease of use. Recommended for larger, long term crops with extensive roots like peppers, tomatoes, or cucumbers. Typically, seedlings in blocks are placed onto slabs. Grodan Expert is the slab that drains the fastest because of its vertical fibers. By far the most popular slab for the hydroponic hobbyist market. Grodan Master is a special wet/dry slab. The top layer is thicker, which stays wetter, while the bottom layer stays drier. In effect it defies gravity, allowing more even distribution of moisture throughout the slab.
