ESB
Also known as: ES Blue, ES x Blueberry
ESB Strain Overview
ESB is a legendary cannabis strain originally bred by Oldtimer1, an old-school English grower dedicated to adapting landrace sativas to indoor environments. Ot1 combined a selected Nigerian Skunk to DJ Short's original Blueberry to create this tamed sativa, ready in 9-10 weeks indoors. The strain represents a cross between ES (a Nigerian x early Skunk #1 hybrid) and DJ Short's original Blueberry released by Sagamarth. ESB is mostly sativa-dominant with a 70/30 sativa-to-indica ratio and can be cultivated both indoors and outdoors, with plants requiring a flowering time of approximately 60-67 days.
The strain is known for providing an "up sativa head" with good buzz but no anxiety like many sativa-dominants, making it particularly popular among musicians. Fleur du Mal has maintained the ESB line for over two decades ever since Oldtimer1 first shared ESB seeds back in the late 1990s. The modern F3 version represents significant advances in the strain's overall fidelity to the original profile, with stabilized habit among plants and strong vigor. Early phenotypes finish in about 50-55 days with moderate strength, while later phenotypes take 65-70 days and are much stronger with "a very happy stone" that has more uplifting effects reminiscent of the Nigerian genetics in its lineage.

ESB Strain Growing Information
ESB can be cultivated indoors and outdoors with a flowering time of 60-67 days. The strain is mostly sativa and requires 9-10 weeks to mature. Early phenotypes finish in about 50-55 days with some tendency toward hermaphroditism as a warning. Later phenotypes take 65-70 days and are much stronger, with yields averaging 43.25g or 86.5g per square foot at 50w/ft. The strain is easy to grow and therefore perfectly suited for inexperienced sativa lovers. Plants stretch about 3 times from 12/12 light cycle, are mostly columnar in form with little branching making them ideal for SOG (Sea of Green), and feature huge sun leaves up to 17 inches across with dense, resin-laden buds that have a high bud-to-leaf ratio.
