Pargro Quick Drain™ (QD) blocks are up to 14% drier than Cultilene® Comfort blocks. Pargro QD slabs are up to 10% drier than our previous Neptune slabs. Jumbo is a particularly good choice when you want to use a big block in an ebb and flow system. If you want a drier top, then opt for the Biggie in your system, since capillary movement will generally not reach above 4” in a block on most flood tables.

The ideal choice for most plants. The easy to use system was designed to accommodate the 1.5” Grodan A-OK Starter Plug and then support the plants growth right through to harvest. New Grodan Improved! New density + new hydrophilic technology = better water distribution and root development. The uniform distribution of water and nutrients throughout the block allows for more efficient use of the entire substrate volume Full saturation of the blocks with no dry spots and improved EC control with less water is achieved in the rootzone due to the uniform, optimized wool resulting in a sustainable water and nutrient use. Improved “re-wettability” able to more easily increase water concentration in the substrate.

Sold as a Case of 64 Hugo 6" x 6" x 6" Gro-Blocks.

Grodan Pargro same quality, same value-priced, now half sized cases of 48 blocks. Plain brown half case sizes. Grodan Pargro QD (Quick Drain) have better quality and drainage than other value-priced rockwool. Grodan Pargro QD Biggie blocks are 14% drier than competitor blocks.

Super light and super versatile. 2 cubic foot bag. Grow Chunks are a larger version (3/4" square) of the popular Grow Cubes. They are great for direct planting or for use as a filling around blocks in containers. They can be easily mixed with other media for increased aeration and added moisture-holding capabilities.

Grodan Delta constitutes the basis for the uniform and perfectly controllable propagation of plants, the condition to be met for powerful and healthy plant growth. Each block has a virtually identical density, flexibility and sturdiness, guaranteeing a uniform distribution of the WC, EC and pH which in turn results in a uniform and high-quality plant.

Growcubes are small loose 1/2” cubes of stonewool. Advantages are better aeration, maximum drainage so that you can hardly ever over water your plant, easy mixing with other loose media (such as expanded clay rocks or coconut fiber), lightweight and much cleaner than peat-based media. The properties of Growcubes make it like a 50/50 mix of absorbent to repellent stonewool.

Gro-Slabs provide the final stage for growing a spectacularly large plant. Transplant your Gro-Block plant onto a slab just like professional growers. They come in clearly marked biodegradable UV resistant sleeves for comfortable handling and algae prevention. Uni-slab - All plant roots are protected and contained for the life of the plant. Due to its size, the Uni-Slab is perfect for one large plant. Uni-Slab has the benefits of a slab with the versatility of a block. Expert slabs have vertical fibers for faster drainage; best for hobbyists. Classic slabs have horizontal fibers for slower drainage; best for hot/dry climates.

• Vertical fibers in Expert slabs provide faster drainage - best for hobbyists.
• Horizontal fibers in Classic slabs provide slower drainage - best for hot/dry climates.

Healthy plant protection. Effectively eliminate harmful insects and powdery mildew, without polluting the environment. Kill bugs on contact without using poison. 1 gallon concentrate mixes with water to make 128 gallons of ready to use spray.

Lost Coast Plant Therapy suffocates and dehydrates soft body insects, their larvae and eggs, powdery mildew, mold and fungus on contact. After saturation of entire plant, our spray will adhere to the target insect, egg case or larvae. It's active ingredients then cause disruption of respiration and digestion. It also penetrates to dehydrate their entire body. Insects can never become immune to this product because they can't get immune to suffocation or dehydration.

Many insects and diseases are eliminated on contact with one application. Others, take repeat application to eliminate the problem.

Our unique formula does not stress the plant and will not damage flowers, fruits or vegetables as long as it is applied under proper lighting and low heat conditions.

Lost Coat Plant Therapy has been laboratory tested by CW Analytical (among others) and found to leave no harmful residue.
