Ep 037: Harvest Plan: Reading Ripeness and Pulling the Room

· Nine weeks into flower, Jeremy walks the 10x10 quadrant-by-quadrant to lay out his harvest strategy and explain how he decides readiness. He covers senescence and the anti-flush stance in living soil, reads fade colour, uses a USB pocket scope on trichomes (clear/cloudy/amber), compares Halitosis and Bransons finishing rates, and explains why he'll pull the whole room at once rather than staggered. He discusses fresh-frozen for hash, whole-plant hang drying in Colorado's dry climate, staged defoliation on harvest day to keep the trim bin clean for hash, and the philosophy of 'early/cloudy/amber = rare/medium/well-done steak.' Also previews the quadrant 4 veg garden (carrots, lettuce, kale, radishes, tomatoes, peppers) and teases yield reporting by quadrant.

Week 9 Walkaround and Harvest Intro

Jeremy opens episode 29 at nine weeks in and says the harvest plan is being made on the fly because you can't enact a plan until the plants are actually ready. He scans quadrant one and points out the fade, senescence, yellows, purples, light greens and golden hues showing through when the lights dim. He previews the USB scope trichome check and emphasises there's no one right way to harvest.

  1. 1. Walk each quadrant visually, note fade colours and overall ripeness
  2. 2. Dim or turn off grow lights to see true fade colours (gold hues appear)
  3. 3. Plan to scope sample buds under USB microscope for trichome check
  4. 4. Use visual + scope combined to decide harvest timing
2:00 — 6:30

Senescence vs Flushing in Living Soil

Jeremy explains cannabis is an annual flowering plant mimicking end of season under 12/12, trying to produce seed. He contrasts hydro forced flushing (where you cut nutrients so the plant cannibalises mobile nutrients) with living soil where you simply stop adding water-soluble feed and let the plant decide when to stop eating. He says a 100-gallon living soil container can fully senesce on its own, and that fade improves smoke quality at the 'out-of-jar' stage because chlorophyll is lower.

  1. 1. Stop adding water-soluble nutrients in the last few weeks
  2. 2. Continue watering the soil to keep microbes alive
  3. 3. Do NOT force a flush with plain water feeding cycles
  4. 4. Let plants stop taking up nutrients on their own accord
  5. 5. Accept that some genetics fade hard (yellow) and others don't (stay purple)
  6. 6. Allow genetics known to fade heavily to do so; don't starve genetics that don't
6:30 — 11:00

Lowering Light and Quadrant Walkthrough

Jeremy walks quadrant two showing the Halitosis fade. He explains the narrow-leaf plants wanted to keep stacking near strong light, so he dimmed the lights in the final weeks to mimic winter and let them finish instead of fox-tailing and frying buds. He discusses how narrow-leaf (sativa-leaning) finishes later than broad-leaf, mentions his preference for mostly cloudy with a little amber rather than a fixed 30% amber target, and raises the hash-maker's case for pulling earlier. He warns against harvesting significantly too early — that isn't preference, it's ignorance.

  1. 1. Observe stacking and fox-tailing near strong lights late in flower
  2. 2. Dim lights when plants stop benefitting from full intensity
  3. 3. Lower temperature to mimic end-of-season winter conditions
  4. 4. Scope narrow-leaf last since they finish after broad-leaf
  5. 5. For hash: pull earlier, before trichomes amber
  6. 6. For flower: wait for mostly cloudy with small percentage amber
9:00 — 14:30

Harvest-All-At-Once vs Staggered Harvest Logistics

Jeremy lays out his real constraint: one dry room. Staggered harvest means rehydrate-dry-rehydrate cycles that ruin drying consistency, so he picks an optimal day and pulls the entire room. On harvest day he spends trim effort on the A-buds for smoke and pushes the B/lower material into the rosin/hash pile. He mentions fresh-frozen for rosin, where harvested material goes straight into a deep freezer and later into a freeze dryer to preserve volatile terpenes. He gives his finish-week framework: 7-week minimum look, 8 weeks as a minimum target, best genetics go 8-12 weeks; anything that finishes in 4-5 weeks isn't worth his time.

  1. 1. Decide whether you have enough dry room capacity for staggered harvest
  2. 2. If only one dry room, pick one optimal date and pull the whole room
  3. 3. Trim A-buds first (priority smoke flower)
  4. 4. Send B-buds and lower material to the hash/rosin pile
  5. 5. Alternative: fresh-frozen harvest straight to deep freezer for rosin/hash
  6. 6. Alternative: use a freeze dryer for fresh-frozen material
  7. 7. Start scoping at 7 weeks, don't target earlier than 8 weeks minimum
13:00 — 15:00

Clear Cloudy Amber — the Steak Metaphor

Jeremy gives his trichome colour framework with the steak metaphor: clear is rare (too young), cloudy is medium (great), amber is well done (couch lock, sleep). For hash you might want rare to medium-rare. For sleep/couch-lock you go fully well done. He encourages experimentation: if you have 4 of the same plant, harvest one today, one at 8 weeks, one at 9 weeks, one at 10 weeks, and taste the difference.

  1. 1. Scope trichomes to classify: clear, cloudy, amber
  2. 2. Clear = too young, cloudy = ideal, amber = fully ripe/couch lock
  3. 3. For hash, pull earlier (more clear/cloudy)
  4. 4. For couch-lock sleep smoke, let more amber develop
  5. 5. Experiment: split 4 same-strain plants across 4 harvest dates
  6. 6. Keep separate drying racks for staggered harvests
14:40 — 16:00

Whole Plant Hang Drying and Staged Defoliation

Jeremy's harvest procedure is whole-plant: scissors on the main stalk, take the entire plant out, and hang it. Because Colorado is dry he'll leave most fan leaves on. To segment the workload, on harvest day he defoliates first — pulling fan leaves with no sugar into the compost pile, leaving leaves with resin/sugar for the trim bin. He notes you can actually defoliate the plants completely a day or two before harvest if labour is tight, stripping everything but buds and sugar leaves in advance.

  1. 1. Grab scissors and chop the main stalk at the base
  2. 2. Take the entire plant out in one piece
  3. 3. Hang whole plant in the dry room
  4. 4. In dry climates like Colorado, leave most fan leaves on
  5. 5. On harvest day, defoliate fan leaves with no sugar first — compost them
  6. 6. Leave leaves with resin/sugar content attached for the trim bin (feeds hash)
  7. 7. If labour-stressed, pre-defoliate days before harvest, stripping to buds + sugar leaves
16:00 — 18:00

Quadrant 4 Veg Garden Update

Jeremy tours the vegetable quadrant which is on only 12 hours of light. Carrots are slow but present, lettuce is popping, he's already harvested the peppers (about a dozen off one plant), tomatoes are pulling off (last of the blossom end rot plant), cherry tomatoes are planned for next round, kale's fully back and ready to eat, radishes are coming in slowly. He notes this is a tiny operation compared to BuildASoil's greenhouse and 40+ employees but it's still giving back something every day.

  1. 1. Thin carrot rows as seedlings crowd
  2. 2. Start eating lettuce leaves as they pop
  3. 3. Harvest kale leaves as they mature back
  4. 4. Pull last tomatoes off including the blossom end rot one
  5. 5. Plan cherry tomatoes for next round for higher yield
17:00 — 22:00

Scope Sampling Technique: Bracts vs Nugs

Jeremy picks two representative samples — one from the loudest/fueliest Halitosis and one from the most advanced Bransons. He explains a crucial gotcha: the bract (the little leaf tip) always shows more amber than the actual nug, so if you only scope bracts you'll harvest too early. He samples actual nug material by pulling buds off with his fingers (carefully, to avoid pinching trichomes), puts them under the USB scope and narrates what he sees: cloudy heads dominate on the Bransons, some amber, some still clear/turning milky, and anthocyanin purple pushing up the trichome stalks. On the Halitosis he sees less amber — less finished — but enough cloudy to justify a harvest, especially given the room is going to hash anyway. He also notes the scope doubles as an IPM tool for spotting russet mites.

  1. 1. Choose representative plants — one per cultivar
  2. 2. Avoid sampling bracts only — they always show more amber than the nug
  3. 3. Pull a small nug off with fingers, avoid pinching trichomes
  4. 4. Set sample on paper under USB microscope
  5. 5. Sample from the top of the canopy — if the top isn't ready, the bottom isn't either
  6. 6. Look for mostly cloudy trichomes with some amber, a few clear turning milky
  7. 7. Scope the same spot repeatedly across days to track progression
  8. 8. Also use scope to check leaf undersides for russet mites and other hard-to-see pests
22:00 — 24:46

Final Decision and Yield Tease

Jeremy confirms he's within acceptable range to harvest both cultivars. He'll document the hanging/drying process across upcoming episodes. Teases a possible yield guessing contest with a giveaway. Praises the Timber grow light for getting plump buds all the way down to the bottom. Previews that trim and final yield will take about a month to report. Notes the whole season's drive is viewer feedback and the BuildASoil customer service team hearing from people who watched the videos.

  1. 1. Commit to a harvest date this week before week 10
  2. 2. Plan 15-16 days of drying time
  3. 3. Plan a week of trimming after drying completes
  4. 4. Report yield per quadrant, possibly per plant if time allows
  5. 5. Solicit viewer comments for round 2 planning

Notable quotes

"You can have a plan but if your plants aren't ready then you can't enact that plan."

Opening framing — harvest planning is subordinate to plant readiness

"That's why it's important not to flush in living soil."

After explaining how water-soluble nutrient inputs late in flower trigger confused new growth

"So flushing is how you stop that in hydro. In living soil, even though you have lots of organic nutrients, as long as you're not adding new water soluble ones, you're just watering your soil."

The core distinction between living soil finishing and hydro flushing

"I want it to get to the point where it does it on its own, not where I'm like saying look at the beautiful fade when it's really just starving."

Jeremy's honesty about distinguishing genuine senescence fade from starvation fade dressed up as quality

"Harvesting significantly too early — I don't think that's a preference, I think that's ignorance."

Drawing the line between personal preference (early vs late within the ripe window) and plain getting it wrong

"All amber's like a well done steak. The cloudy is kind of like medium. And that clear is like rare."

Jeremy's signature ripeness metaphor — the steak analogy for trichome colour

"If you're trying to put yourself in the couch lock 100% and that's what you're using it for, for sleep, you might want to go fully freaking well done."

Closing the steak metaphor — matching ripeness to intended effect

"The bract will always show more amber than the rest of the bud."

The critical sampling gotcha — don't fool yourself by only scoping bract tips
