RAW Calcium/Mag is a balanced supplement delivering 15% Calcium and 3% Magnesium in a fully water-soluble form. This optimized blend supports strong cell structure, nutrient mobility, and photosynthesis without leaving salt buildup in the growing media.

Calcium and magnesium deficiencies are among the most common issues in intensive cultivation—and they often appear together. RAW Calcium/Mag solves this with a precise formulation of calcium nitrate and magnesium sulfate.

  • Calcium for Structure: Strengthens cell walls, promotes root growth, and helps prevent issues like tip burn and blossom end rot.

  • Magnesium for Energy: Central to chlorophyll, driving photosynthesis and ensuring efficient nutrient metabolism.

  • An Added Edge: Because this formula uses calcium nitrate, plants also receive a touch of clean nitrate nitrogen. This small addition improves uptake synergy without overloading the crop. It’s safe through bloom and won’t trigger unwanted stretch.

  • Optimized Balance: The 15:3 ratio of calcium to magnesium ensures both nutrients are delivered harmoniously, preventing lockouts and maintaining a clean, efficient root zone.

RAW Calcium/Mag is ideal for preventing and correcting deficiencies, fine-tuning nutrient recipes, and supporting high-quality growth and production. Its concentrated, 100% soluble form means a little goes a long way in soil, hydroponics, or fertigation.

Heat tape

The tape works well the only issue that I have is being that it is wider it does not stretch well, while wrapping my tumblers for sublimation, other than that it is a really good tape.

This is not good heat tape.
Number of Items: 2
I bought this for sublimation and t-shirt making and because you get a lot for a decent price. Well, just spend the money on the good golden tape because this stuff doesn't hold up like that. I had a few cups ruined because the tape released while in the oven. Not cool at all. I don't have a LLC to buy cups in bulk, so it wasn't 1 or 2 bucks this take ruined. So be aware that this tape is poop before using.

A must have.

I recently purchased the MEBMIK 6 Rolls 20mm x 33m (108ft) Blue Heat Tape High Temperature Heat Resistant Tape for Heat Sublimation Press Vinyl, and I couldn't be more satisfied. This tape has truly exceeded my expectations. One of the standout features is that it doesn't leave any marks or residue behind, which is crucial for a clean, professional finish. It holds up well under high temperatures, making it perfect for heat sublimation and vinyl projects. The tape is durable and reliable, ensuring my projects come out looking great every time. Overall, I highly recommend this heat tape for anyone involved in heat transfer or sublimation projects. It's an excellent product that performs exactly as promised.

Works well and easy to use for sublimation
Number of Items: 6
I’ve been using this heat tape for a few different sublimation projects—mugs, shirts, and a couple of random DIY gifts. It holds up great under heat. No slipping, no weird residue left behind on my blanks, and it peels off cleanly every time. The stickiness is just right—not so strong that it’s a pain to remove, but strong enough to keep designs in place while pressing. I also like that you get several rolls in the pack, which makes it a great value for the price. It’s easy to work with and cuts cleanly, which is helpful when you’re lining up small designs. Overall, this has made my sublimation process a lot smoother.
