Mephisto Madness (testers)

Was having humidity issues as its cold here now and we have electric heat and it got down in the 30's in terms of relative humidity. Turned off the main fan for now and am running a little humidifier now and getting up around 60% which is much better I think. Plants seems to be doing well after having been topped, I didn't notice really any slowing down in terms of growth, pretty sure they got bigger that day if I remember correctly. Will be topping the last smaller plant, the Hulk Smash asap. I lost one during germination so this one is behind quite a few days, but looking good. Thanks for any views and I"ll try to stay on top of this. Cheers.
