Switch from 18h to 24h of light

Hello. In the beginning, I started with 18 hours of light to save electricity, and also because I thought that there would be no difference between 18h and 24h. I read that plants grow faster using a 24h schedule. Is it too late to switch to 24 hours of light? Will it effect the plants? Thanks.

nope u can switch back ur all good man

The earlier you switch the better, are you sure about the 24 hour stuff by the way? I'm a fan of nature, I think giving them a little down time is good, but everyone has there own method, best of lucK!

guy if u are growing photo ............do not change to the 24/0 u want to keep it at the 18/6
if u are growing autos....................i do a 20/4 with good results

by the way if u are going to go to 24/0 u should invest into a Co2 system or bag or something u will see better results
when the lights are on the plants love Co2........when the lights are off they love Oxygen

You can veg photo under 24/0 with no negative results. I have tried 18/6,20/4,22/2 and the 24/0 seems to keep the nodes a little tighter while the 18/6 shot up more. Like justugh said, autos ran best under 20/4 and seemed to stress under 24/0.
