So, we had a problem. One of each of the strains failed to sprout, so I've got one each of the AK-48 & Northern Lights that sprouted this past Tuesday, and the ones that just sprouted today. I plan to veg for 6-8 weeks so it'll be a wash by that time anyway. Currently under lights 24 hours daily, plan to move to 20/4 light cycle 1 week from today. There's two lights in the tent currently a 2011 150 watt (2 watt diodes) Grow Led Hydro-discontinued shortly after release and replaced by the 2011 180 watt - GLH . I'll be taking delivery on Monday for 2 new 2011 180 Watt Spectra LED grow lights it's a 36"x36" grow space that'll total 360 watts of LED growing power-should be sufficient for some big bud by my reckoning. Depending on how my personal budget goes I "may" throw in another 1 for a total of 530 watts LED power-sit tight on that one though. The 150 watt light I have now has to go back Mike the owner of GLH kindly allowed me to swap it out so I'd have a matching set. Here's a pic of the plants 1 tall & 1 short NL have an identical of both of the AK48.
