Soil Test: LSD-25 Auto

Woohoo! Now that summer is behind me, it’s time to start a new grow. I’m repeating my previous LSD-25 grow this round, using the same setup as previously but using my own soil blend this time. The previous round yielded just over 1 gram per watt, which isn’t bad, but I’m hoping this grow will perform even better. Setup -------------------------------- Tent A tiny 40x40 cm tent that I normally use as a small drying tent. It's basic but works well and gets the job done. Light I'm using my trusted Viparspectra P600. It's a small, 95 W, full-spectrum light that is dimmable. It offers an almost even cover of light in the small tent. According to my PAR meter, the difference in light is less than 5% between the center and the corners. Ventilation A small and basic fan/carbon filter combo, where I placed the filter outside the tent to save space inside. I'm using a mechanical timer to control the exhaust fan since running it nonstop during the germination and veg period is unnecessary. Air circulation Regular clip fans are too big to use in such a small tent, so I use two PC fans attached to the tent poles with a few things from the hardware store. Electrical A WiFi-enabled smart power strip is used to connect everything electrical. It has built-in scheduling, so there is no need to use a separate timer for the light. Container I’m using a sub-irrigated planter with 31 liters of medium and a reservoir for 7.5 liters of water. Medium I’m testing out my new soil blend to see how it will perform compared to the commercial product I used in the last grow. Cultivar -------------------------------- FastBuds LSD-25 Auto THC Up to 21% CBD < 1% Harvest Indoor 400 – 500 gr/m2 Height 70 – 120 cm Flowering 9 – 10 weeks Genes Sativa 35%/Indica 65% Germination -------------------------------- I started germination by dropping the seed into a glass of water mixed with myco with fulvic acid. The myco product I use has kelp in it as well, and multiple studies show how kelp benefits germination and rooting. I also use some of this myco water to soak the root riot plug before planting. To increase the stability, I turned the plug upside down, made a small hole, and planted the seed after soaking it overnight. The plug now stands on a small propagation tray on a heating mat in my other tent. The light is set at 24 Hours with a DLI of 10. Now we wait. Edit: I could see the first signs of germination after only 24 hours, and now after 36 hours we definitely have germination!
