Lots of updates since the last post.
8/24 (Wed) - I worked on reducing humidity in the tent. It's been above 60%, and I need to get it lower in flower.
- Turned the room dehumidifier down from 40% to 35%.
- Removed the exhaust filter. It's really dirty. I'll clean and re-install it this weekend.
- Replaced the intake filter. The old one was pretty caked-on dirty.
- At this point I realized that the intake fan was only at about 30%... I thought it was on high. Could this have been the problem all along?
Either way it appears the humidity problem is fixed, as long as the dehumidifier stays on (that's another problem). Not only is the humidity lower in the tent, the temperature is now higher, because the exhaust doesn't need to work as hard. Of course, higher temperature for me means temps in the upper 70s so I'll take it
8/25 (Thu) - Everyone grew another inch last night. Instead of oranges they're starting to smell like when you leave orange juice out for a while; kind of orange-skunk. Very interesting!
- All of the top buds got a pinch and wiggle this morning to try to slow them down.
- I raised my light by the last 1" that the hangers allow, to 14" above the top bud. To go any further I need to switch out the cord hangers with carbiners, or hang directly on the bar.
- I also raised the back rack up a few more inches and adjusted all of the fans.
- The tower fan is now horizontal across the middle blowing up, along with the floor fan. This should keep plenty of airflow through the canopy.
- Dehumidifier kicked off for about 4 hours, from 12p-4p. Manually reset.
8/26 (Fri) - It looks like they grew about 1/2 inch, so they may be slowing down?
- I pinched and bent the tallest buds over to give me a little more room and some consistency on the canopy. I'm being really careful not to touch the new buds.
- Dehumidifier kicked off at 11:30pm, reset at 6am.
Not much room to get in the tent from the sides anymore. Today I had to get in the side to bend the top buds over and felt like a puppet master, with my elbows up as high as possible to keep them off the buds
I hate that I'm running out of room because they look so good stretching. If they stretch too far, plan A is to lean the tallest buds over to the side. There's about 16" from the first net to the second, so there is quite a bit of play in the stems. I think I can get 6" by leaning the buds over, and also get a more even canopy. The downside is that I will probably touch the buds more than I want. We'll see if it comes to that.
For now I'm just adding water to the res (with pH down). Adding the Big Bud spiked the res up over 1500ppm (3 ec) and I'm trying to get it back down to 1400ppm (2.8 ec). The plants are doing great with it, though. As soon as I see it get below 1400ppm I'll start adding nutes.
I'll probably remove more undergrowth this weekend. Any buds that have no chance at making the canopy will be cut. I'm also trying to thin out the middle to make sure I have good airflow. And of course, I'll keep bending and pinching buds as needed.
I also have some work to do this weekend to the tent. I need to solve the problem with the dehumidifier, putting it up higher so it can drain into the 'sink'. I need to clean and re-install the exhaust filter. I may even have some other new equipment to install... but more about that later.
