GT Silica – Strengthen Plant Cell Walls for Healthier Growth

GT Silica is a concentrated potassium silicate additive designed to supply plants with bioavailable silica – a mineral not naturally present in most hydroponic solutions. Regular use helps fortify plant cell walls, making them more resilient against pests, diseases, environmental stress, and physical damage.

Why Use GT Silica?

  • Strengthens cell walls for improved structural integrity.
  • Boosts resistance to fungal infections, insect attacks, and environmental stress.
  • Increases chlorophyll production for more efficient photosynthesis and CO2 uptake.
  • Helps maintain leaf variegation and reduces the risk of brown spotting.
  • Suitable for all growth stages – vegetative through to maturity.

Directions for Use

Hydroponics / Semi-Hydro: Add 5ml per litre of plain water, stir thoroughly, and let sit for 15 minutes before adding nutrients. Adjust pH to 5.5–6.5 after mixing.

Soil / Potting Mix: Add 2–3ml per litre of plain water, stir thoroughly, and let sit for 15 minutes before watering plants.

Tip: Always mix GT Silica into water before adding other nutrients to avoid precipitation and ensure even distribution. Handle with care – wear gloves and eye protection when using the concentrate.

VERY sturdy and almost foolproof
Size: 36in, Color: 3-layer, Size: 36in, Color: 3-layer
This kit is made of real wooden planks, and metal pipes and fittings. Installation is simple- assemble each end of the kit, hold it up to the wall using a magnetic level, mark the four holes for each mounting piece, then repeat with the other side. You'll need a tape measure to make sure that the ends aren't too close together or too far apart, and measure from the ceiling or floor to ensure a level surface. You will want a second set of hands for most of the install process. This kit comes with good molly bolts and strong screws that match the finish of the metal hardware. Make sure that each side of the unit is oriented the same way, as I had to flip one side after neglecting to do so at first. Retaining brackets and wood screws are included for securing each shelf to the metal frame. A power drill makes this part very easy, and can be done mostly solo as the brackets can be pinched to clip onto the frame while you attach the screws. Once installed, this unit is VERY sturdy. There is no play or wobbling when testing the attachment to the wall. If there is, tighten your screws and make sure that the fittings to the wall mounts are hand-tight. These shelves can handle heavy kitchen staples and books with no problem. It is a tier more expensive than most Ikea-style shelving, but that's worth it for the confidence that my dry goods are safely stored in a convenient place.

Very Sturdy Industrial Shelves with a High-End Look
Size: 48in, Color: 3-layer
The OLDRAINBOW Industrial Pipe Shelves with Wood Planks 3 Tier 48in are very sturdy and have a high-end look once installed. The combination of metal pipes and wood planks gives them a strong, rustic-industrial style that looks more expensive than expected. They feel solid and well-built, not flimsy at all. Once mounted, the shelves feel very stable and can hold a good amount of weight, which makes them practical for books, decor, or kitchen items. Overall, these shelves are both functional and visually impressive. They add a polished, high-end feel to the space and I am very happy with them.

Really sturdy. Beautiful addition in Kitchen
Size: 36in, Color: 3-layer
We put this up in our kitchen to hold our recipe books and other odds and ends. It is really beautiful and ties the space together nicely with the blank wall we had. It’s sturdy to hold several recipe books and a great price point for the quality. The only thing was that the second shelf did not line up from one pipe to the other. The top and bottom shelves aligned perfectly, so the pipes were leveled, but it seems that the pipes in the middle were not equal distance and the shelf wobbles. We’ll be putting something underneath one end to balance it out.
