humidity coming out above the plants, so here's an idea I came up with that definitely works (so far).

I used PVC pipe fittings and silicone to make the following modifications to my humidifier.

Adding an elbow is still under investigation. I worry about condensation backing up.
 
My Next Experiment - "Two is one and one is none"

My fellow military vets are familiar with the phrase, "Two is one and one is none."

Well, that phrase inspired my newest curiosity - adding BluMat Carrots to an AutoPot grow.

When I was laying out the tubing for my AutoPots I went looking for a "Tee" fitting. The first one I found was in my BluMat fittings. I tested the size and it fit the same I.D. Then I noticed a fitting that is technically a "Tee" but one outlet is for the tiny tubing that BluMats uses.

Thus, this idea: Use the tiny carrots to sample and satisfy the moisture for the top 3 inches of the pot's coco.

Those carrots are getting the same nutrients that the bottom of the AutoPots are getting.

I'm only doing this on one pot for now. It also happens to be the one pot that is not getting outside air bubbles to the bottom of the pot.

Day 34 - Update

  • E.C. is now at 2.0 (ish)
  • I am going to expand my BluMats to all buckets. What the heck
  • Added a second humidifier - tough to get to 65%
  • Topped Genius Juice (Today is Day 30 for GJ) - She got tall
  • I raised light intensity to 100%, yet PPFD was under 600.
  • That may be ideal, but I would rather lower the light and reduce energy waste.


Added 2nd Humidifier:

Day 41
Day 1 of Flower​

  • I switched the lights this morning, so 12 hours ends at 8:00 tonight.
  • All have been topped.
  • Only very yellow leaves have been removed.
  • All 3 plants are leveled out on the nutrients and have a deep green color.

I usually train like crazy, but I am not training other than topping this grow.

I'm waiting until the end of week 3 of Flower before any significant defoliation.

The main stems look thick and strong (like bull).

They are sharing the tent with two Brothers Grimm plants.

Day 42 - Issues - VPD


• Looks like the weather has turned cool enough that I need a heater in the tent.

• 79ºF to 65ºF is not an ideal "swing."

• I prefer 80ºF - 70º Swing with a goal of 77 as a Sweet Spot

• I'll also switch to 60% humidity (down from 65)

• By the end of 2nd week of flower will hold at 55%

• When flowers form, I usually switch to 45% until harvest.
