OK cool, then I will start cracking the whip first thing tomorrow morning. We have been experiencing a very uncharacteristically cold Winter for the last month or so, so I'm not really up for going out to my workshop where the grow box lives right now! Actually I have just had thought; if I simply alter the timing of my existing 18 hour regimen so that when the lights-out period occurs, the sun is at it's most intense, I will be slurping up much more light than now, without impacting power-consumption at all. The plants should also be somewhat warmer during these cold nights we've been experiencing. Good news is of course being in the Southern hemisphere, The longest night has come and gone!
