Semi-Hydro Mix – inert substrate for reservoir-based growing

Semi-Hydro Mix gives roots a mineral framework with air pockets and access to a controlled reservoir. It is a system choice, not just a different bag of soil.

More to know

  • Inert mineral base: does not behave like soil
  • Reservoir use: works with suitable semi-hydro containers
  • No built-in feed: requires a measured nutrient routine
  • Reusable structure: can be cleaned and reused where appropriate

How to get started

Because the medium is inert, nutrients must come from the solution. Use a fertiliser suited to the setup and keep strength appropriate for the plant and stage of adaptation.

Transition notes

Some plants adapt easily; others stall or lose old roots during transition. Start with healthy plants and monitor roots closely during the first weeks.

Key points

This mix is built around structure first. Use it as a complete potting mix, or blend it into a base soil to adjust airflow and drying speed.

Watering should match the pot size and root mass. Check moisture at depth and adjust your routine after the first few cycles.

Mixing guide

  • Moisten dry components before potting so the mix settles evenly.
  • Choose pot size for the root ball, not for the top growth.
  • Top-dress with the same mix to reduce surface compaction.

Nice but dissapointing
So it sometimes stays cool but if it’s under a blanket and you have your body on it at all it will get warm but the spots you don’t use will get cool sometimes. I am very disappointed in the material though because it’s like my dry skin scratched the pillow case all over which makes me question it and I don’t think I would buy again.

Cool, Comfortable, and Worth Every Penny!
Color: Light Gray, Size: Standard
I’m honestly impressed with these pillowcases! From the first night, I could feel the difference—they stay noticeably cool, which is perfect if you tend to sleep hot like I do. The fabric feels silky smooth against the skin without being slippery, and it’s really gentle on both my hair and face. I’ve also noticed I wake up less sweaty and more comfortable overall. They fit my pillows well and don’t slip off during the night, which is a big plus. After washing, they held up great—no fading, shrinking, or loss of softness. If you’re looking for pillowcases that actually help keep you cool and comfortable through the night, these are definitely worth it. I’ll be buying more!

Extremely cold, silky, gentle on hair
Color: White, Size: Queen
This was so cold when I removed it from the package that at first I thought it would be too cold. It was as if it had been in a freezer. I really like how silky it is on my face. (I can't stand a rough feeling pillowcase.) It is also gentle on my curly hair. The pillowcase can warm up from being slept on, but a shift of just a few inches gets back to wonderful cold. I highly recommend this as an extremely cool, silky smooth fabric. These are much colder than my very expensive miracle sheets.

Freaking Amazing 🤩
I never write reviews but these pillow cases absolutely deserve one!!! These are absolutely amazing! So soft and cool! I sweat so bad every night!! I wake up and my hair, shirt and pillow are drenched!!! I slipped these bad boys on as soon as they came in, and let me tell you! They were cold to the touch, I woke up this morning and I wasn’t sweating! I thought $20 something dollars was a little expensive for 2 pillow cases but was totally worth it! We love love love them!🩷🩷🩷Hubby approved😉
