They are in 6 gallon bags. If I drenched them every time I watered, I probably could have gotten away with watering every 2-3 days, but I like checking on them every day, so I'd give them a light watering once a day, usually with a weak fert mix. Water pH is generally around 6.5 when I water. They're pretty old plants by now (cloned around 6 months ago) and are about 5' tall after multiple prunings and lots of attention. They've looked super strong and healthy (with the exception of a short case of mites) the entire time until a few weeks ago when I switched them to bloom, changed thier bulb and started phasing in some bloom fert.
