BuildASoil: 2x4 Grow Tent Season 3 // Week 4 Flower Update, PPFD Testing & Light Adjustments

Episode 16: Week 16 Series Update, Week 4 Flower Progress, PPFD Testing & Optimizing Mid-Flower DLI In this episode, Season 3 of the 2x4 Grow Tent series continues with the Week 16 series update as plants reach Week 4 (Day 28) of flower. I take a close look at plant development, compare two very different genetic expressions, and fine-tune the lighting as the garden moves into the second half of bloom. I begin with a Week 4 flower update, discussing where each cultivar currently sits in its flowering timeline and how genetics influence overall flower development. I compare the Cocoon and Silver Lotus side by side while talking about expected finishing times, equatorial genetics, flowering duration, and why different cultivars can look completely different even at the exact same stage of flower. Next, I inspect both EarthBoxes, checking reservoir levels, feeder root activity, and the living soil biology beneath the mulch layer. I explain how the previous top dress is breaking down, how the plants are consuming nutrients during mid-flower, and why EarthBoxes continue to provide an incredibly simple and effective way to grow high-quality living soil cannabis with minimal maintenance. From there, I compare overall flower structure, resin production, aromas, canopy development, and plant health between the Cocoon and Silver Lotus phenotypes. I also discuss how flower stacking changes after the stretch phase and what growers should expect as plants shift their energy toward building density and resin production during the second half of bloom. Finally, I perform PPFD measurements inside both 2x4 tents, evaluate light intensity across the canopy, and adjust the lighting schedule to better match mid-flower conditions. I explain why reducing Daily Light Integral (DLI) can sometimes be more beneficial than simply dimming the fixture, how different light designs distribute PPFD, and why maintaining proper light intensity becomes increasingly important as flowers continue to mature.
