Over the years, I’ve run a few side-by-side experiments with growing cannabis plants. I am almost always surprised by something, and I thought you might be too. So I decided to keep a list of all my marijuana-growing experiments in one place. You can also check back here to see whatever is the current experiment. I also decided to include other past marijuana grow journals for you to check out while you’re here. Contact us and let us know what experiments you want to see!
Here are the cannabis experiments and grow journals starting from the most recent. Scroll down for a quick overview of each one!
Experiment Grow Journals
- Defoliation vs No Defoliation in the Flowering Stage
- Does a 3-Day Dark Period Before Harvest Increase THC?
- Topped vs Natural with Auto-flowering Plants
- LED Grow Light Showdown: Mars Hydro TSL-2000W vs Spider Farmer SF-2000
- Super Soil (“Just Add Water” Soil) vs Coco Coir
- LECs vs HLG 300 LEDs
- Vipaspectra LEDs vs HPS
Other Past Grow Journals (no experiment)
- Nebula’s 65W LED Mini Tent Grow Journal (HLG 65 LED Grow Light)
- Nebula’s 100W Spider Farmer SF-1000 LED Grow Journal
- 250W HPS Grow Journal – Hydroponic
- 250W HPS Grow Journal – Autoflowering strains
- 600W HPS Grow Journal – Hydroponic
More past grow journals soon. I’m slowly going through all my old grows on Instagram and turning them into cannabis grow journals on the website. My hope is to one day contribute to the body of science surrounding cannabis cultivation.
Defoliation vs No Defoliation in the Flowering Stage
Does a 3-Day Dark Period Before Harvest Increase THC?
I’ll make a graphic soon, but here’s a quick summary of the results:
- Before 3-day dark period: 18.4% THC average
- After 3-day dark period: 19.7% THC average
Topped vs Natural with Auto-flowering Plants
