Growing (September 2026)
Shown here is a grow inside a grow box measuring 2’ deep, 3’ tall and 4’ wide. There are a couple of 80mm fans, one pushing and one pulling. There are 8x 4’ 6500k fluorescent bulbs in a custom built fixture. Soil moisture is monitored via the weight of the grow over time.
In the plots, you will see “Tare A,B,C”.
Tare A is the water-back set point. This is the weight to which the grow is watered back to with each irrigation event. It helps me as the gardener maintain a desired moisture level. Notice that the target soil moisture is fine tuned through the time period shown. As the gardener, I can adjust the set point as I perceive the plants’ needs.
Tare B is the absolute weight of the grow.
I use Tare C for various things, such as measuring harvest.
The four containers on the top shelf are labeled so that they can be referenced in other pictures. The bottom shelf shows Thai basil being cloned from a friend.
24/0 light cycle for 16 days by mistake. 14/10 thereafter. Evapotranspiration is faster with lights on. The upward steps are irrigation events.

The evapotranspiration slows with the lights off. It would be interesting to plot the derivative to see when the evapotranspiration is greatest and least.
Cloned Thai basil looking good.
Oh no! Attack of the aphids!! I sprayed them vigorously with jets of water. I then pruned them back. The aphids left them alone after that for several days.
Time to harvest and prune!
Top: Before harvest | Bottom: After harvest | 119g of basil harvested

Before/after harvest of a clone from my friend
212g of basil harvested
I noticed a few aphids remained. These peppers were pruned again and then moved outside.
Beginning to see roots on some clones.

Roots on 3/4 of the clones. Going into dirt next!
