Hey,

Journaling a grow I recently completed here.

This post shows info on time, location, and yield. And then I run some calculations based on the dataset.

 

Notes on the grow:

Method

Grow method is DWC hydro, under LED light, fertilizer is mostly aquaponic water processed through a small bio-filter.

Genetics

Plants were mostly home-made non-feminized seeds, with a few retail feminized seeds added to fill the canopy.

 

Notes on the data tracked:

Time

Time was tracked from seed to vegetation, to start of flowering, to harvest, and then when cure has started.

Yield

How much dried cannabis flower was harvested. This could be trim, smalls and top flower.

Location

There are 24 spaces in the setup, and each space is given a number. With this data, we can see at what spaces do best, regardless of the plant.

 

Notes on this viz:

Summary is given top left. A (fairly useless) date breakdown is shown per plant below.

Yield stats are given via the bar graph. Yield per day is shown by bar width, sum yield is shown by colour. Hover or tap each bar to see some relative data for that plant. Averages for each cultivar name is shown via the line.

Harvest was done in a 3 day period. For some reason my date calculations don’t reflect that. Not a big deal for looking at one grow, but something to fix as the data expands.

Null plant numbers represent females that were identified, but grew so small they weren’t worth trimming, and were weighed collectively.

Summary Notes:

A quarter of the total yield was from one plant (RF x Ze #1). Said another way, 25% of the yield came from less than 10% of the plant count. At the time of writing, I have yet to review each plant, but this is an attractive measure if the plant is likeable. There is also a locational element at play here, this plant grew under directly under a light, whereas not every location has that advantage.

This grow was done to audition an array of home-made seeds, not the retail feminized seeds. That’s likely why the yields were lower across the feminized plants, they were used as canopy filler. One qualitative note, the feminized seeds smell ‘better’ than my home-made stuff at this stage of curing, on average.

The most interesting plant was one I did not identify, or keep (RF x Ze #0). Yield was poor, but in retrospect timing was better than average, I could have harvested it in week 5 or 6. The flowers differ in appearance from its siblings, as does its aroma; it smells of creamy pine, and earthy shale while curing. Perhaps not the most appetizing smells, but they are unique in the group.
