What should I do if my cannabis plant is stretching?
- When cannabis plants stretch, they are at the same time consuming large quantities of nutrients, specifically Nitrogen and Phosphorus, along with a great quantity of water. By cutting back on these macronutrients and reducing irrigation for the first few weeks of flowering, we can have a positive influence on reducing plant stretching.

What causes cannabis stretch?
The greater the difference between day and night greenhouse temperatures, the more stretch occurs. Bedding plants may become too tall if they are started too soon, are spaced too closely, are shaded by overhead hanging baskets, or are grown in low light greenhouses caused by old plastic.
When does cannabis stretch the most?
Temperatures in the grow room Indeed, research has shown that most of the stretching takes place during the first few hours of the morning, so simply by reducing temperatures for a couple of hours at daybreak to 5ºC below those at night for the first 3 weeks of flowering, we can almost eliminate the stretch completely.
When does flower stretch end?
When you grow indoors, flowering will begin once you switch your lights to 10-12 hours of darkness. For most cannabis strains, the flowering period will last about 7-9 weeks, although some sativas require even longer for their buds to mature.
Can leggy seedlings recover?
Hardening off the plants or transplanting them outside may also help with legginess. Most leggy plants become sturdier once they are growing outside. Some leggy seedlings can be saved with modified transplanting techniques.
How do you get big stalks?
How To Get Thicker Stems (And Keep Your Plants Healthy)
- You can get thicker stems on your plants by providing them with the required amount of sunlight, water, aeration, nitrogen, and space.
- If your plant does not get the required amount of sunlight, it will grow tall and spindly.
Why is my plant growing tall and skinny?
A very common mistake some gardeners make when starting their seeds can include depriving their seedlings of the light they need to thrive and grow. If your seedlings are tall, “leggy” or thin, understand this is caused by the plant having to “reach” for their light source.
How do you stop seedlings going leggy?
You can reduce the changes of the seedling becoming leggy by ensuring you germinate it in the lightest possible conditions. Also turn the container every couple of days so the light is not constantly drawing on one side of the seedling.
How do I stop leggy seedlings?
There are four surefire ways to prevent your seedlings from becoming leggy and they all involve light manipulation.
- Provide direct light.
- Provide artificial light.
- Adjust supplemental light.
- Brush the seedlings gently with your hand or a ruler several times a day to strengthen the stems.
What to do with seedlings after they sprout?
Spoon out the seedlings to avoid damaging the stem by lifting them. Use a good sterile soil again and water them well immediately. You can use any container, but peat pots and other compostable materials allow for easy insertion into the garden bed without damaging roots.
When do white hairs turn to buds?
The stigmas in the pistils are long hairs and can help you determine when a plant is ready for harvest. In the first few weeks of flowering or when a bud is formed, you should see numerous white hairs coming out of it. For the first 4-5 weeks, the stigmas will remain white.
Should I remove fan leaves during flowering?
Yes you should – but with the correct technique. A proper thinning will remove 20-40% of the mid to upper foliage every 5-7 days. Removing these fan leaves opens up light and produces better air exchange to the lower canopy.
