Rooting gels

What it is

A product with rooting hormone (almost always indole-3-butyric acid, an auxin) that tells the cut stem it has to grow roots. It comes as a gel, a powder or a liquid.

Why gel

The gel sticks to the cut and seals it: it keeps air out of the stem (a bubble inside can kill the clone) and fungi too, and the hormone stays right where the roots will come out.

How to use

  1. Put a little gel in a separate cap (never dip the clone in the jar: it contaminates it).
  2. Cut the clone and dip its base, 1 or 2 cm, in the gel.
  3. Push it into the substrate without pressing, so the gel doesn't smear off.
  4. Throw out what's left in the cap.

Watch out

With light, heat and air the hormone breaks down: an open jar doesn't last long and is kept closed, in a cool, dark place. Without rooting gel, cannabis clones still root, just more slowly and with more losses.

▲ Pros

  • Clones start with more health and less stress
  • Fewer die in the tray
  • They start 2 days ahead

▼ Cons

  • Only works for clones

🎮 Practice it in UnderGrow

It's called rooting gel and it's an optional add-on (shop › add-ons). You pick it when taking clones ("with rooting gel") and it uses 1 use per clone. When planted they start with more health, less stress and 2 game days (2 real h) ahead, and fewer die in the tray. The open jar expires after 30 game days (30 real h).
