# Wilting with a light, dry pot: likely causes and fixes

> Wilting with a light, dry pot on cannabis is most often Underwatering or Dry, water-repellent medium (water runs straight through). How to tell them apart, the fix for each and what recovery looks like.

Also called: underwatered, thirsty plant, dry soil drooping, plant wilted dry, leaves hanging limp dry pot.

## Likely causes, most likely first

### Underwatering (Likely)

- Kind: Root zone; urgency: Act within a day or two
- Fix: Water slowly in 2-3 passes until 10-20% runoff, so the whole root ball wets. Water when the pot is clearly lighter, before the plant droops. Mild late-flower dry-back is a house-endorsed practice for some cultivars (Caplan 2019), but wilting is not.
- Recovery: Turgor returns within 1-6 hours of watering.
- Confirm: Lift the pot and check moisture at depth: Lift the pot right after a full watering to learn its wet weight, then lift before each watering. Water when it is clearly lighter (about half the added water gone). Push a finger or a moisture probe 5 cm (2 in) down. Heavy for 3-4+ days with droop: overwatering. Very light with limp papery leaves: thirst.

### Dry, water-repellent medium (water runs straight through) (Less likely)

- Kind: Root zone; urgency: Deal with it this week
- Fix: Rewet slowly: small amounts every 10-15 minutes, or bottom-soak the pot for 20-30 minutes; a drop of plant-safe wetting agent helps peat. Don't let peat mixes go bone dry again.
- Recovery: Pot gains its normal wet weight and holds it for a day or more.
- Confirm: Lift the pot and check moisture at depth: Lift the pot right after a full watering to learn its wet weight, then lift before each watering. Water when it is clearly lighter (about half the added water gone). Push a finger or a moisture probe 5 cm (2 in) down. Heavy for 3-4+ days with droop: overwatering. Very light with limp papery leaves: thirst.
