Hi All,
Happy Week 6! Not much this week. Some defoliation of the largest leaves on day 37, and then a second round on day 41, to remove the last few light blocking leaves and the lowest/ weakest flowers. I'm very surprised at how much OG Kush stretched. She's the same height at her Sour Diesel sister. Next to each other they look like twins....so much so, that I counted my remaining SD and OGK seeds to make sure I didn't mislabel one!
Last week I noticed some of the top leaves on the SD plant were yellowing and curling. I now think this is light burn from the grow light. She is the tallest plant and sits underneath the middle of the lamp where the light is most intense. I've been trying to keep the light ~ 18 inches from her top, but it seems like the more I adjust the light, the more she stretches in response. This is something I have to work with for now, but will keep in mind when planning my next grow.
La Kush Cake is looking short, squat, dense, and delicious! This plant was the most in need of defoliation. Removing the leaves exposed a good number of buds which I didn't even see before! BONUS!
Environmental conditions this week: Keeping the light settings the same as last week: intensity 100% with UV/IR channel at 25%. I will keep the settings there until the plants are done stretching and I can set my final light height, especially with the SD getting sun-burned. The exhaust fan is on full speed 10/10. It's helped bring down the humidity into the mid-50s, but unfortunately is also dropping the air temp. Temps are low-60s to low-70s. I'm not going to do anything more to adjust RH or temp. With the winter settling in, the house is cold at night and only a little warmer during the day. And right now, my drive not to fight an uphill battle is more powerful than my drive to obsessively manage VPD. Regardless, the plants look very happy and healthy!
See you all next week. Thanks for checking in!
I applied some beneficial nematodes a little over a week ago and the gnat problem has almost gotten under control. I might do another application later this week or next.
I also put up some sticky traps to catch the adult fliers.
@PartTimeUnicorn,
Love to hear that. Seeing those gnats in the tent is such a downer! The zevo that I put in the tent seems to have resolved the problem for me too. I haven't seen any new gnats in a few days.
I top dressed my soil two days ago because the plants were showing pre-flower. I didn't see any gnats crawling around in the soil when I pulled back to plastic cover sheet. Hopefully it holds up.
Have you had any issues with fungas gnats in the earthboxes? Seems like whenever I top dress, I get an infestation of them. I did add some beneficial nematodes recently and it seems to be helping.
@PartTimeUnicorn
Dude! Fucking YES!
I haven't put up my week 3 post yet, but I have started noticing them. I ran a power cord with a zevo bug catcher into the tent. It's quelled them but there's still a few stragglers. The bug catcher emits a blue light to attract the gnats. I use them in my house during the summer, especially near the sink and fruit bowl. They work well.
I had gnats in a lime tree pot a few years ago and used nematodes with good effect, but ended up changing the soil when I moved the plant outside the following spring. Otherwise I'm trying not to put more water in the basin than can be absorbed in a day or two. The fungal gnats drive me fucking crazy though!
The earth boxes are so damp that I think gnats are going to be a problem the whole time. I asked my GF for some of the milled mustard seed from build a soil for Xmas. Its supposed to kill of gnats and boost mycelial growth. Hopefully that helps. I'll let you know if it does.
Good luck hunting!
