So I’ve got my lights on a 18:6 schedule but the way I’ve done it tube ineffectively made the plants nocturnal lol so I was wondering how can I swap the schedule so the lights are on in the day not at night ? Haha
With the age of your plants you should be able to just swap over as you want - if you wanted you could give 24 hours of light then just change to your new schedule the following day.
