Watering

A lot of beginners struggle with under/overwatering, and to add to the confusion, in both cases the plant with wilt. To ensure proper watering plants should be watered until there is some drainage from the pot. Fabric pots provide the best drainage as long as they are raised from the surface they are sitting on.

The pH of the water should be between 6.2 and 6.7. If it's too high for too low, the nutrient intake will be blocked. This is an especially important rule to observe when using nutrient formulas as to not waste them! It's important to note that pH is a logarithmic scale, meaning that 6 pH is 10 times more acidic than 7 pH. More on pH

It's a good idea to check your tap water with a digital pH meter as it will vary depending on your geographical location. If water is too alkaline (pH too high) a few drops of lemon juice or vinegar can be added. To increase pH you can add dolomite lime. In general, cannabis prefers an acidic environment (<7 pH).

Water stakes

A form of automatic watering that allows the plant to “drink” water through a straw. Ideal if you need to leave a plant unattended for a few days.
