Small changes today. While I am noticing a little leaf growth on the ww's I'm also finding that some of their hanging roots have withered. Hopefully new ones will take their place shortly. The air pump is working fine with the 4-12" stones, so the plants should be getting the message from below.
The Euforias still look undecided, although their roots continue to grow slowly. Both strains have minor tip burning in common.
I'm now experiencing what I've read so much about with these machines... heat.
It spiked to 88 but seems to stay at 86 for the most part. The humidity in the room has it's usual swings, 30's-40's, yet the box's interior is 16-22%. The room humidifier seems to have little effect.
If a sudden burst of energy overtakes me later I will duct the two fan-forced outlets from the upper (lamp & ballast housing) portion of the cabinet directly to the room's outlet duct merging them from a "Y". This way, the heat can be evacuated while not prematurely taxing the carbon filter. If the cabinet's fans are not strong enough to vent through my entire duct run I'll install an inline inductor fan to assist. Either way, that should render a kinder environment in the box.
The moms are getting a bit hairy but I've been reluctant to trim them as I'm holding out as long as I can to be certain the producer's crop takes off.
Thanks again to all of you for being so supportive. This place is really like a catharsis for cannabis growers!
