lfg_CanopyCraft Soaked seed in distilled water for 12 Hrs, transferred to paper towel (24 Hrs). After taproot emerged, placed directly in substrate. Watered every 3-6 hours with 100-300 mL purified water (pH 6.8, EC 180) Seedling emerged and cotyledons opened within 24 Hours, placed under humidity dome. PPFD: 140 uMol/M^2/Sec DLI: 10.08 Mol/M^2/Day None of this time counts towards seedling age. Looking forward to this grow! Correcting mistakes from my previous grow by improving my skills in LST and canopy management. I'm only doing 1 plant this time to make sure I get it down, but I think improving this aspect will make up for the reduced quantity of plants in terms of yield.

lfg_CanopyCraft More Data for Grow Period 1A (Days 1-6): DLI AVG: 13.7 Mol/M^2/Day INF EC AVG: 0.554 mS/cm EFF EC AVG: 0.580 mS/cm Seedling leaf tips looking a little burned, I'm not too worried as I've seen this before. To mitigate this I'll be increasing EC more slowly than normal over the next few days. Leaves are looking a little twisted because I started feeding a little too early, but I'd rather feed too early than too late so I'm okay with that. Great start!

I'm doing the math and logging VPD once every 3 days now, I record it the same day I'm logging effluent EC. Moved her into the larger tent at the end of the week. Uncharacteristically low humidity weather is messing with me though. I thought I'd start LST sometime next week, but it seems like she's starting it for me lol.

I plan to defoliate a bit more during week 6, after they've stretched a bit. Dealing with rising EC, I'll be fertigating more next week to bring that down a little bit.

lfg_CanopyCraft More Data for Grow Period 1B (Days 1-7, running total 35): DLI AVG: 45.7 Mol/M^2/Day INF EC AVG: 1.198 mS/cm EFF EC AVG: 1.083 mS/cm VPD AVG: 1.25 kPa Despite my original plan, I did take off a few leaves that were blocking budsites this week. I think it recovered nicely though. Next week I plan to defoliate a little more aggressively. EC has come down naturally, the extra growth during the stretch is probably helping a ton for this. I also installed the auto-watering system, this gives the plant about 150mL of nutrient water every 6 hours. As the water needs increase, I'll raise the amount of water it's getting as well.
