If your cannabis plants shows signs of drooping, often the plant is getting too much or too little water, but not always. Drooping can be caused by….

First, make sure you’re using proper cannabis nutrients for your growing medium. They should be formulated for a plant like tomatoes, and they should have a different feeding schedule for the Vegetative (Grow) and Flowering (Bloom) stage.

An old-fashioned watering can will get the job done, but they typically don’t hold a lot of water at a time, which is inconvenient if you’re growing a lot of plants

These 1’x2′ plastic plant trays work well if they fit your space. You can fit four of them in a 2’x4′ grow tent (this is the grow tent I use) with up to two plants each as long as your plant containers are 11″ wide or smaller at the base.

When growing in composted and amended soil, the soil itself is made to slowly provide nutrients to your plant throughout its life. However, if you’re regularly watering until you get a significant amount of runoff, you’ll also be washing away some of your nutrients.

As for when to water your plant next, experts agree. They say that when you use soil, you should water the plants once the first couple of inches of soil feels dry. Another telltale sign is if the container feels exceptionally light. Are you adding nutrients to the water regularly? If so, add enough water to get up to 20% runoff that drains out of the container’s bottom. This process prevents a build-up in your soil.

Experience Helps

Finally, you have to consider your growing medium. If you have a small garden, manual watering with a traditional watering can is fine. If you have a more extensive operation, it is worth investing in an auto-watering cannabis system. It will help take the stress out of matters. When all else fails, the weight of your pots can serve as a useful watering guide.
