Iāve done 24/7 for years never had any problems.
A lot of the time I just found it easier to do like that. If it wasnāt one thing it was another (failed timer or no timer at all, people needing to turn on a light during dark period....list goes on) so I just did 24/7 for simplicity and never looked back.
Absolutely will work... there is no argument for me there. Just need to adjust the light intensity accordingly. When we get into optimization there are always things that can improve our grows. Definitely not necessity but in many cases an improvement.
Is it always cost effective, absolutely not.
Is it gonna make or break a grow, absolutely not
Is it a necessity, absolutely not.
Will every person see a benefit from it, absolutely not.
Is understanding the benefits, costs, impacts and reasoning beneficial, absolutely yes.
An informed decision is the right decision.
