Yes, it is okay to give autoflowers a 12/12 light schedule. However, it is important to understand that this will result in smaller yields and less vigorous growth compared to longer light cycles like 18/6 or 20/4.
Here are some things to consider:
* Smaller Yields: Autoflowers grown on a 12/12 light schedule will produce smaller yields compared to those grown on longer light cycles. This is because they will have less time to photosynthesize and produce energy for growth.
* Less Vigorous Growth: Autoflowers grown on a 12/12 light schedule will also exhibit less vigorous growth. This is because they will have less energy to fuel their growth.
* Potential Benefits: There are some potential benefits to growing autoflowers on a 12/12 light schedule. For example, it can be easier to manage heat in warm climates. Additionally, it can be helpful if you are growing autoflowers alongside photoperiod plants, as you can keep them all on the same light schedule.
Overall, while it is possible to grow autoflowers on a 12/12 light schedule, it is generally not recommended. If you want to maximize your yields and growth, it is best to use a longer light cycle.
