Keep it on cycle if possible, but with subdued light. In other words, keep the same light cycle, but try to shield the plant from direct or heavy light for aday or two, when it perks back up. This allows them to rest and gets the roots to re-fill the new void they have to spread out in.Once they repair and start growing into the new container, they will be ready for full light. Usually 3 or 4 days is enough, and you don't have to keep them dark, just half powered or shaded.
Hey so I just put my seed in water to germinate and my plan is to put it in the ground in this green house out back but before I do that I was going to put my seed in a cup and let it grow for a fue weeks in my sun room but the light schedule will be different in the sun room then the green house so idk if it's going to mess up the plants schedule when I transplant. If someone could help me that would be wonderful thank u
