How many hours does the T5 tube light have to be on?

A customer has a question or concerns and I hope we can get some opinions on it, thanks

“How many hours l have to leave the T5 tube light at the very first stage of the growing before l put them under the light in main growing room? I did check your instructions but in the T5 tube light section, it doesn’t say for how many hours the t5 tube light have to be on before I out them in the bigger pots and transfer them into the main room.”

You want to keep lights on for 18-6 18 on 6 off
That would be the best schedule to start with
And keep same schedule threw out the Veg cycle
Then 12/12 fir flowering when that time comes
Fyi plants need the dark period as much as the light period :+1:
Happy growing
And welcome to the forum
