Seedlings under T5s only for how long

When should I transition seedlings from T5 lights to the big LEDs? Both are autos… only one week old. Still under T5 s. I’m wanting to kick the big lights on… I figured just start them up high and move them down slowly , but over how long of time?

Stick with the t5s for a couple weeks. No use using all that power when it is not needed. T5s are great for vegg anyway, especially in the 4000k and up color


4th week and still going strong under 4 T5 6500k bulbs. I have 2 MH hoods waiting but no point as long as they keep growing like they are.
