TheCalyxLaboratory C99 – Week 1: The Sativa Rocket Launches! 🍍🚀
Welcome to the solo-run in the mini-tent! While the high-end sponsor strains are taking over the big setup, this report is all about a legendary, fast-flowering classic: C99 (Cinderella 99) by Female Seeds!
Running in my 40x40 cm tent, this project is designed to test how much punch, flavor, and efficiency you can pull out of a compact, single-plant Sativa setup under targeted lighting.
The Setup for this Run:
Tent: 40x40 cm (Solo-Tent)
Lighting: Viparspectra XS1500 Pro (tuned to an efficient sweet spot)
Medium: Coco-Perlite (50/50)
Goal: A tightly trained, highly optimized single-plant setup focusing on structure, massive headbud development, and those iconic sweet pineapple terps.
Current Status (Week 1):
The seed is officially soaking in its pH-adjusted water bath, getting ready to crack. Once the taproot shows, it’ll move into its starter medium to kick off the journey in the small lab.
Excited to run this absolute Sativa masterpiece alongside the big tent. Let's see how fast this rocket takes off! 🍍✨

TheCalyxLaboratory 👸 C99 (Female Seeds) - The Vital Sativa Stretch!
Current Stats: PPFD: 200 | EC: 1.0 | pH: 5.8
Cinderella 99 is living up to her Sativa heritage right out of the gate. She stretched a tiny bit more than the others in the first few days searching for the light (typical for the strain), but has now settled in perfectly at the current 200 PPFD. Her stem is slowly getting sturdier, and the first jagged leaves look lush green and absolutely healthy. With the current EC of 1.0 at pH 5.8, she seems to have the perfect starting conditions to really take off now. Here is to a great vegetative stage! 🌿☀️

TheCalyxLaboratory 🌿 C99 (Cinderella 99) – End of Week 2: Repotting Day & Into the Final Home!
Weekly Update:
The little C99 has been developing brilliantly over the past two weeks. However, the small starter cup (Red Solo Cup) reached its absolute limit—during repotting, a gorgeous, dense, and healthy white root system was revealed, having completely root-bound the cup. Time for the next big step! 🚀
Setup & Details:
Container: Upgraded from the small cup to an 8.5-liter final pot
Medium: Freshly mixed 50/50 Coco-Perlite mix (ideal for maximum aeration and drainage)
Special Feature: An Airdome is installed at the bottom to supply the root zone with extra oxygen.
Lighting (PPFD): Stable at 400 PPFD
Feeding / Watering: Thoroughly watered in right after repotting with an EC of 1.4 and a pH of 5.8.
Observations:
The plant shows strong vigor, though it was starting to show slightly lighter leaves in the old cup as the nutrients were running low. The fresh coco/perlite mix combined with the tuned EC of 1.4 and pH 5.8 gives her the exact fuel boost she needs. The roots look pristine, and thanks to the Airdome and the increased volume, she is ready to explode in growth.
Ready for Week 3! 🌿✨
C99 and Bubblegummer were my first strains back then. I still have the C99 F2 regular from Cannapot in the fridge, I definitely need to start that up sometime^^
