I am going to try my best to explain this one Today a new sysem and fan were fitted to the grow room...600 wt and a fan that actually does the job properly.
At the moment I have my seeds still in Root Riot cubes with the intention of repotting them tomorrow. They are under a 125 enviro light at the moment also. Now I will be going away for a short break over the Bank Holiday. I have a dilemma on my hands as I'm not sure whether to keep them under the 125 until I get back next Monday, or whether to start the new lights and fan tomorrow. I will be going away Thursday, so will it be safe to leave them under just a 125 light for that period of time?
I am worried about leaving the plants under new lights as I dont know what speed etc they will grow? I have someone coming in to check if they need water but that is all.
What would you do? I need the benefit of experience here? Will it stunt the plants growth? They stand like watercress atm to give you an idea of how they look... I hope this makes sense?
Any advice appreciated...

personaly i would keep them under the enviro and leave the new light till you get back

They'll be fine under the enviro. We do almost all our vegging under a 125 W blue. I wouldn't want to go away for a long weekend having just set up a brand new lighting system. I'd run the new fan though.

i'm the same...all vegging /cuttings/bonzai mum are under a 125 blue viro 24/24 (cos of cuts would prefer to go 20/4 but space is an issue)..i mean same as squirrel by the way ..
