i agree. With lights on, certain systems run and when the lights are off, certain systems run.Ok plants don't rest I agree. They change processes during lights on and off. Both are crucial imo.
The plant is pre-programmed. It will act accordingly to the input of the environment.They absolutely do get used to a light cycle and will start to droop a bit as they slow transpiration rates in anticipation of a dark cycle.
The plants programmed (amongst other things) to measure the duration of daylight /darkness IE: being able to take it from veg stage to flower stage by reducing/increasing amount of light
Less light, winter is coming - time to reproduce ( flower mode )
Longer light, its still summer - keep vegging.
IN A HEALTHY PLANT:
In darkness, the leaves "droop" because their is no need for them to stay up. Its dark.. no sun...no need to use that system.
If they droop and flop around, you have an unhealthy plant.
If they droop and still have strength ..its healthy.
If it droops and the light is on, again you have a problem.
What do you mean by high light. INTENSITY?They will also do then when they can no longer keep up the rates of photosynthesis and transition more towards photorespiration if under very high light.
If so, yes and no.
The argument here is CAN YOU VEG PLANTS UNDER 24 HOURS OF LIGHT .
I say you can and the O.P says you cant.
what do you say?
