ller until the point where they will eventually fall over because their support structure cannot hold them anymore.
This can be prevented by keeping lights closer to plants or providing additional support via string or stakes.
- Place the LED grow light about 12 inches above the target plant to begin.
- Examine how the plant leaves react to it. If the leaves droop and curl, you should raise the light a few inches higher.
- However, if the leaves are in good form and growing fast, you might try lowering the light to get closer to the plant, maybe as close as 6 inches from the top of the plant.
These are all the known and approved methods of how to stop plants from growing too tall. If you employ any of them, you will get bigger yields and a healthier and more stable plant.
However, if your main priority is yield, then topping your plants is the best choice for you because it causes the biggest increase in yield potential.
If you try any of the methods given above, please note that while some of them will be more effective than others under certain circumstances, none of them will work 100% of the time.
