After introducing 7 common reasons why cannabis plants grow slow, is there any way we can make it grow faster? Yes of course! In addition to watering, humidity, and temperature factors, we also need to consider the following aspects:
Gentle Air Circulation – You probably know if it seems stuffy in your grow space. Plants, like humans, enjoy a gentle breeze to go along with their warm, sunny day. Air circulation prevents hot spots while ensuring plants get plenty of access to fresh air. Fresh air contains CO2, which is crucial to photosynthesis (making energy out of light). As a result of fresh air and great air circulation, plants not only grow faster with stronger stems, they are more resistant to white powdery mildew, bud rot, fungus gnats, spider mites, and other unwanted visitors.
Quick Cheat Sheet to Fixing Environment
- Fans – Fans equalize the temperature and humidity between two areas by moving air around. Just remember that they cannot alter the overall temperature or humidity. For that, you’ll need….
- Humidifier – Raises temperature, raises humidity
- Swamp cooler/evaporative cooler – Lowers temperature, raises humidity
- Dehumidifier – Raises temperature and lowers humidity
- Air Conditioner (AC) – Lowers temperature, lowers humidity
3.) Optimize Your Grow Lights
Choose a quality grow light and keep it the recommended distance away from your seedlings for the fastest growth. If the light feels hot on your hand where your plants are, it definitely should be moved further away. We recommend LED grow lights. It is becoming more and more popular, which is a trend.
LEDs – LED grow light technology has improved by leaps and bounds over the last decade but especially in the last 2-3 years. There are good and bad brands out there, but many newer LEDs are designed specifically for growing cannabis. The best LEDs produce captivating bud quality and yields, so the brand you choose is important.

4.) Seeds / Genetics
Start with Good Genetics – Start with good seeds/clones for the best results. Old seeds, found seeds, and unhealthy clones can result in slow-growing plants. On top of that, certain strains tend to germinate better or grow faster than others. That means you’ll get the fastest-growing plants if you start with tested genetics from a trustworthy breeder.
5.) Respond Quickly to Problems
Look at your plants for at least a minute or two every day. It’s really easy to overlook problems if you just water them and go. Taking a minute to really look at each plant and its leaves will often reveal problems right as they’re starting.
Take 2-3 minutes each day to look for…
- Leaf spots or discoloration
- Bugs or webbing
- White patches or mold
- Curling or twisted growth
- Yellow or brown leaf tips
Although just pay attention to the overall color and appearance of plants. If your plant seems “off” to you, it probably is. Healthy leaves are green without discoloration. If leaves look sick, don’t ignore it! Figure out why. As long as you react quickly, you can solve almost any problem without growth slowing down much, if at all.
