Home growing, written down
Trying to grow
better weed.
Building the tools I wish I had. I’m Jason. I grow at home, get things wrong and write it down. This is where the projects live.
- 9,572 strains on file
- 901 with lab numbers
- 134 flowering times, straight from breeders
- 0 trackers on this site
- The garage lab: still mostly a garage
- The tools: live

What I’m up to.
Everything here has an honest status. Some of it works. Some of it is a pile of parts.
Strain library
9,572 names. 901 with lab numbers. Most still need the growing part.
Look one upLiveTools
Harvest window, VPD and daily light. They run in your browser and keep nothing.
Do some mathSlow burnThe garage lab
Still mostly a garage. I’m done with tents, so it’s getting real walls and its own air conditioning. Demo comes first.
Read the planLiveSilly shirts
Shirts, hoodies, stickers, an apron, a bag and a puzzle. “Support a local grower.” The local grower is me.
See the shopThe strain library
9,572 strains. Most are a name and not much else.
I pulled together open data: names, breeders and lab numbers from state-licensed labs. What’s missing is the growing part. 134 have a flowering time, and every one came from the breeder’s own page. I could use help with the rest.

Tools
Three calculations I got tired of doing in my head.
Flip + 8 to 9 weeks
Harvest window
Flip date plus the breeder’s weeks. Gives a window, never a verdict.

VPD
Temperature and humidity in, vapor pressure deficit out, with a chart of where you sit.

Daily light
PPFD and hours on. How much light the plants get in a day.
OpenThe mascot
This is Mr Dookie.
He’s a fly. He showed up early and never left. He doesn’t say anything on this site. He watches me overwater things and keeps it to himself.
He does talk on his own site, where he runs a clothing line. Of course he does.

Notes as I go.
- September 24, 2026ExperimentExperiment 001: homemade auto-waterer vs self-watering potsSame room, same soil, two ways of watering, a sensor on each. This is how the test will run. I’ll post the result whatever it says.
- September 20, 2026BuildThe garage: the plan, in the order I have to do itOne garage bay, split into a place to build things and a place to grow. I’m done with tents. Nothing alive goes in until the room holds its temperature. Right now it’s still mostly a garage.
- September 18, 2026GrowMeasure the room before you grow in itI can’t feel humidity. Neither can you. Notes on logging a room for a few days before anything alive goes in.
Growing something?
The tools are free and ask for nothing: VPD, daily light, and a harvest window that won’t pretend to know better than your trichomes.
