Purple Haze - Week by Week Grow Diary & Strain Review

Purple Haze started a little rough, but once the setup improved, the run really began to take shape. From there, it turned into a steady indoor grow with solid structure, good flower development, and a finish worth sticking around for.

Grow Setup

Grow Diary

Weeks 0-1 - Germination & Early Seedling

Purple Haze was started directly in substrate after an overnight soak in aerated filtered water. The grower used 1 gallon plastic pots because space was limited, even though they normally prefer starting in larger fabric pots.

The mix was mostly peat, lava rock, worm castings, Gai Green 4-4-4, glacial rock dust, and mosquito bits, with microbes and fungi added after sprout.

By week 1 the seedling was only 3 cm tall, running under 18 hours of light, with a first feeding of Soluble Root Zone, liquid kelp, and cal-mag. Watering was minimal, only once for the week, and PPFD was kept around 250 at canopy.

Weeks 2-3 - Early Vegetative Development

The first real setback showed up early. The grower flagged what looked like an iron deficiency, then followed that with more yellowing tied to watering and pH issues.

That part is worth noting because it could have stalled the whole run. Instead, a strong Boogie Brew compost tea soak turned things around quickly, with most of the plants bouncing back within two days.

During the same stretch, Purple Haze was hardened off a little, moved out of the smaller tent and into a 4x8 under the bigger lights, with canopy PPFD adjusted to around 500.

Weeks 4-5 - Settling In & Transplant

Week 4 was steady rather than dramatic. Purple Haze got a proper drench and foliar spray of Boogie Brew tea while the grower was still working out the final home. Week 5 was the real pivot point.

The plant had clearly outgrown the 1 gallon pot, so it was transplanted into a 20 gallon container in the Gorilla 4x8, given a light haircut, some leaf tucking, and topped on the main stem.

The reused soil was amended with Boogie Brew base and boost, insect frass, Gai Green 4-4-4, neem seed meal, and rock dust. That is where the run stopped looking cramped and started looking like a proper veg plant.

Weeks 6-7 - Structure Building

Week 6 was about space and follow-through. The second 4x8 tent finally came online, Purple Haze was moved over, and the grower decided not to transplant again, choosing instead to work the 20 gallon pot harder later in the run if needed.

The plant had already shown a clear improvement in size after the transplant. By week 7, the structure was one of the standout features.

The grower kept calling out the branch angles, the lower growth reaching canopy height, and the fact that the plant was building the right kind of frame for what came next. Compost tea, BSF frass, and neem seed meal kept it moving.

Weeks 8-9 - ScrOG Setup & Easy Veg

This is where the shape really started to matter. In week 8, at a reported 61 cm, the structure looked so good the grower said it almost did not need a net, but the ScrOG went in anyway. 

Week 9 stayed easy. Most of the work was just tucking shoots under the net, with one compost-tea-based watering around 700 ppm and kelp plus cal-mag in the mix.

This was also the point where the grower impulse-bought the Bestva Spirit-X fixtures, setting up the tent for a stronger finish to veg and the coming flower phase.

Weeks 10-11 - Final Veg Push

Week 10 brought the lighting upgrade. The grower swapped into matched Bestva Spirit-X fixtures and felt much better about having a stronger, more even setup for the space.

Around the same point the plants were lollipopped and top-dressed with Gai Green 4-4-4, fish bone meal, neem seed meal, insect frass, glacial rock dust, compost tea grounds, and a Boogie Brew watering.

One more week of veg was the plan. Week 11 then turned into the last hard push before the flip, with hotter and drier conditions than intended, lights driven harder, and three waterings that included Epsom salt, potassium sulphate, fish hydrolysate, and Boogie Brew.

Weeks 12-13 - Flip & Early Flower

The first 12/12 week brought exactly what you would expect from a Haze line like this. Stretch kicked off quickly.

A second net layer went in to stop future flop, negative pressure in the tent became a concern, and the pots were topped off with more soil. The grower also added a biochar top dress mixed with Boogie Brew and sifted worm castings.

By the next week, the high CFM bars were finally installed and the upper net attached. Purple Haze was already stretching into it nicely, with good spacing and not much foliage blocking the bud sites.

Temps were still hotter than ideal, but the dehumidifier in the lung room was helping keep humidity and VPD in line.

Weeks 14-15 - Flower Development

Mid flower looked strong. Week 14 notes described buds stacking close together, continued stretch, good airflow, and solid light penetration through the plant.

Temperatures came down a little, but the tent was still warmer than ideal, with the grower planning a gradual step-down into harvest. Week 15 kept the same direction.

Purple Haze was described as a really nice-looking plant with a sweet, amazing smell, good leaf spacing, strong structure around the bud sites, and trichomes developing nicely.

The grower also caught a thermostat issue that had the house sitting around 77°F instead of 74°F and corrected it.

Weeks 16-17 - Late Flower Pressure

Late flower was where the environment started pushing back. In week 16 the plant was reported at 102 cm under 12 hours of light, with 31 °C day temperature and 55% humidity.

Even with the light only halfway up, heat was still a problem.

The grower also got behind on watering and came back to an emptied humidifier, but Purple Haze still kept stretching, frosting up, and building density while throwing a super sweet smell. Week 17 was more of the same, just louder.

Light intensity was dialed down because the tent was getting too hot, the plant was drinking hard, compost tea came back in, and the grower flat-out said 20 gallons was too small for the kind of plants they were growing.

The buds kept stretching, stacking, and putting on girth anyway.

Weeks 18-20 - Ripening, Harvest & Drying

Week 18 brought the finish into view. Purple Haze was described as looking and smelling amazing, with an almost white sage look and feel to the flowers.

The top cola showed a little light bleaching, trichomes were starting to mature, feeding had stopped, and the last watering was chilled down to 64. By week 19 the plant came down.

The grower only watered once with cooled water, noted a final swell in the buds, and described the smell in exactly the kind of terms that kept showing up through the whole back half of the run: lemony, sweet, and very much in the lane they like from sativa-type flowers. 

The colas were long and on the skinnier side, some close to 2 feet, but there were plenty of them and the smaller buds filled out well. Drying was done at 63°F and 60% humidity with fans and a dehumidifier.

The week 20 harvest block logged a 10/10 score, 135 days total, normal difficulty, energetic, creative, happy effects, and citrus, cream, sour taste.

A later trim note added that she dried in about 10 days, was easy to trim because the leaves were tiny and covered in resin, and came across as citrusy, sweet, and candy-like.

Detailed Observations & Grower’s Reflections

The clearest theme in this diary is structure. Purple Haze was not described as a messy plant. Quite the opposite.

The grower kept coming back to the branch angle, lower growth catching up to canopy, the clean spacing through the leaves, and the fact that bud sites were not getting buried.

Once the ScrOG went up, that shape made sense. It gave the plant room to spread, airflow through the frame, and a cleaner path into flower.

The second big takeaway is that the plant kept going even when conditions were not perfect.

Early deficiency, watering and pH issues, a cramped start, hotter and drier tent conditions than planned, negative pressure, a dry humidifier, and a pot that eventually felt too small all showed up in the notes.

Purple Haze still kept stretching, stacking, frosting, and building a sweet lemony profile right into harvest.

Challenges & Solutions

Purple Haze had a rougher start than the finish suggests. The first issue was early stress in the small starter pots, with iron-deficiency signs followed by yellowing linked to watering and pH issues.

A strong Boogie Brew compost tea, added microbes and fungi, and the move into the bigger tent helped steady everything out fast.

Later on, the pressure points shifted to space and environment. The plant outgrew the 1 gallon pot, was squeezed into a 20 gallon container, and by late flower the grower was clear that even that felt too small for the size and thirst of the plant.

Heat, negative pressure, and one stretch with an emptied humidifier also needed managing, so the response was practical: transplant, extra netting, airflow upgrades, top-dressing, dehumidifier use, and closer watering control.

Even with that, the plant kept stretching, frosting up, and stacking through flower.

Purple Haze: Final Result and Strain Review

Purple Haze finished this run as a structured, trainable plant that clearly improved once it had the root space and tent space to work properly.

The final flower shape leaned long and slimmer rather than squat and chunky, but there was plenty of length on the colas and good fill through the smaller buds.

The profile stayed consistent from late flower into trim: sweet at first, then lemony, then citrusy and candy-like after dry.

The final verdict from the diary is strong. The harvest block rated the run 10/10 and logged energetic, creative, happy effects with citrus, cream, sour taste. One thing does need to stay transparent.

Yield reporting on the page is inconsistent. The grower later wrote that the plant gave 13 oz, but the structured harvest block lists 28.35 g wet and 368.54 g dry per plant, which do not line up cleanly.
