Zauberkraut grows LSD by Barneys Farm

2024-01-02: A First-Time Grower's Journal I'm Zauberkraut, and I'm documenting my first cannabis growing experience along with the development of a custom climate control system. The system consists of a microcontroller with sensors and relays to maintain optimal growing conditions. Once completed, I plan to share all documentation and files for others to replicate. Current Plants: Luna and Sunny are LSD strain cuttings, received and planted on December 20th in 20L (5.28 gallon) pots. They share space with other varieties (OG Kush and Gogurtz, which might be documented separately). Growing Medium and Nutrients: Primary Medium: GO!ON Pflanzerde soil from Hagebaumarkt (notable for high water retention compared to Compo Sana Flower Soil) Current Fertilizer: BIOBIZZ GROW (seeking recommendations for all-in-one alternatives) Soil Amendments: Mycorrhiza Environmental Parameters: pH Targets: Watering at 5.8-6.0, drainage measured at approximately 6.5 (drainage water removed after collection) Relative Humidity: Maintained at 55% Temperature: 23°C during light cycles, 19-20°C during dark periods | Plant | Height | Stem Diameter | Training | Luna | 14.8cm| 6.0mm| Topped + LST | | Sunny| 15cm| 6.4mm| Topped + LST | I'll continue updating this journal with environmental data visualizations once the climate control system is operational. –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– Update 2024-01-03: Yesterday I made some findings, I want to share with you in the following passages. The topics are divided into light, air, pests. Let's start with the most frightening topic. Pests! Yesterday I saw some insect flying around in the tent, a little later another one, or the same one again. One way or another, I certainly killed it and identified it as mourning gnat. Today I saw another one again so I think this means WAR. I already have a pack of Steinernema feltiae nematodes and will apply them later after training the plants. Next topic is regarding the lights. As far as I have researched the matter, I am giving my plants too much light, so they are probably lacking CO2 to properly deal with about 1000 PPFD. Some more, some less. This directly leads us to my newest investment: a preassure reducing fitting for soda stream bottle with photosensor for night shutdown. It's supposed to be used for fish tanks and costed around 65€. If my calculations are right, then I roughly will need about 7,5-10kg CO2 per grow, but for now I am just happy with increasing the CO2 by any value. Indeed, today I even decided to do 30 minutes sports in the grow room windows closed, just to increase CO2 levels. Plant Statistics (as of current date): | Plant | Height | Stem Diameter | Training | Luna | 17.5cm| 7mm| LST | | Sunny| 20cm| 7mm| LST | I think it's fascinating to measure these numbers. The stem diameter increased by 13% just over night. To make those measurements more precise I'll take them at the same time of day each day from now on, so the calculated growth rate is more precise. I definitely should put the data in an excel sheet..eventually.... If I am at it, I might watch some other characteristics or properties too, maybe you guys got any recommendations?
