Single Medusa F1

drakkon The Medusa F1 seedling appears healthy and is growing. It resides in my office under an Iongrid S22 LED lamp that hangs from the underside of a motorized height-adjustable desk. The light intensity is currently set to 6 out of 10. The motorized desk makes it easy to adjust the lamp's height. A tiny USB-powered electric fan and the room's HVAC registers provide air circulation. The plant, light and desk are not in a tent, so the plant simply exists in the room's ambient temperature and humidity. Other than my usual HVAC settings, I don't plan to control the room's temperature and humidity. So far, the plant has received water only, without any fertilizer.

drakkon The Medusa F1 has received no nutrients yet, beyond what is already in the FoxFarm Happy Frog soil. It continues to grow nicely and will soon be ready for transplanting and training. I plan to put it in Happy Frog soil in a "yellow" size air pot (~2.2 gal), but haven't yet decided whether to top it or not. Light intensity remains at 6 out of 10, and the plant has grown just a little closer to the lamp.

drakkon On day 19, the Medusa F1 was transplanted into a "yellow" size air pot with FoxFarm Happy Frog soil amended with just a touch of pumice. Her roots and the transplant-hole were sprinkled with mycorrhizae granules. She exhibited no signs of transplant shock whatsoever, so I went ahead and topped her and removed her first-node branches and leaves 24 hours later (day 20). Light intensity remains at 6 out of 10, and she's getting a little closer to the lamp as she grows.

drakkon The Medusa F1 continues to grow and gain in height. She started showing her first flowers toward the end of the week, but I'll call this the last week of her vegetative phase. She now has eight main branches, two each sprouting from nodes 2, 3, 4, and 5. I trained her four upper branches and main stem, hoping to achieve an even canopy and even radial distribution. My goal is to arrange the bottom four branches as a cross-shape (+), and the upper four branches as a cross, too, but rotated 45 degrees in relation to the lower branches (see top-view photo). I also removed a few leaves, tucked a few others, and pruned a handful of her lowest secondary shoots. She was thirstier this week compared to last, and received half-strength vegetative nutrients with each watering.

drakkon The Medusa F1 is in the flowering stage now, with many small flowers clearly visible. Light defoliation and mild LST training performed to encourage a few additional tops beyond the eight main branches. She's undergoing a growth spurt, as shown by photos from days 33 and 37. Compared to the Milky Way F1 I'm growing next to her, this Medusa F1 is taller and has longer internodes. Lamp-to-plant distance maintained by adjusting the height of the lamp or raising the plant. I recently began notching up the light intensity setting for short periods (from 6 to 7 or 8). Waterings now include both vegetative and bloom nutrients, and this where I admit that my watering volume entries are merely estimates. I mix nutrients in a jug, which I usually pour directly from while manually top-watering several different plants. This makes measuring exact volumes difficult. The ambient temps and humidity are creeping up as summer sets in, but I don't expect them to become a problem as long as I keep my eye on it and run the AC sufficiently.
