Awesome! yea the super HPS is just a great bulb for flowering. I run a rail now so more or less have two 600 now as well
. I also use the Humboldt County products (all three) foliar and I have a feeling these also helped. I am running PPM at 1267 (literally just checked haha). I had it up higher, buds loved it, leaves got a bit curled. Took it down, my veg clones are at around 600 right now and the oldest topped one is going crazy! Two more seeds just cracked, hoping one turns out male so I can make some hella good seeds. Time to build a bigger veg cabinet!
