    Hi guys,

    I have 2 600 watt dimmable ballasts that have a 50%, 60%, 75% and 100% settings.

    My little ones are about 3 weeks old and about 3inches tall and under the MH bulbs.

    My question is should I be running the ballasts at full blast (100%) from the start, or being so young and in vegetative mode is running them at 50 or 60% more than enough and wait till there bigger or even wait till flowering to turn it up to 100%?

    Just not sure if the extra power/lumens will speed growth or not at this age and period or if the extra lumens are wasted..

    Thanks for your time :)
