Grape Ape: DWC Small Batch

Day 1 of week 2: She's coming along. Roots started showing through the bottom the basket today. Been giving her top feedings throughout the week. RH has been terribly low (30%) so have added a little misting humidifier to the tent. So far its working great. Today I noticed the temperature in the tent was about 80 F - normally its 72 F during the day. Discovered my exhaust fan wasn't moving any air out the tent. Fan turned out to be working ok but the outer pre-filter on the outside of the carbon filter looked a bit dirty. Removed it, vacuumed it off, put it back on and air is moving again. Hopefully that's the end of it - not sure if a replacement of the larger carbon filter is imminent at this point or not. Can anyone speak to the life expectancy of these things? I would have thought I'd get at least 2 years out of it - the one I have is only a year old. ----------- Day 10: We may have a mutant on our hands. No sign of any new growth above the top leaves and the top leaves seem to be fused together. One of the top leaves is deformed and looks like a ducks foot. Some little side branches have spouted above the first node but I don't know that they're doing anything. I'll keep an eye on her but she may need to be evicted from the tent. 🤞
