Good luck with your Fast and Vast Cannafan. She will make some good oil and butter for you. She smoked good too.
Here is one of my Fast and Vast plants from my 2015 spring/summer grow. She is about 4 feet tall here. This is after a major defol. She had just started flowering. She was beautiful and powerful.
Here is her trunk. She is in a 100% Perlite Hempy 3 gallon bucket with a paint strainer under a Mars-Hydro MarsII 900 watt LED. My experience is mainly with just Autos using the Hempy technique. I have tried in dirt and DWC with little success, meaning low harvest rates 1 - 3 oz. All my Hempy grows gave high harvests of excellent potent medicine, over 6 oz is the normal with some nearing 10 and higher. Love the Hempy technique.
