Fully showing sex now, two Males. womp-womp.
The day before the balls became very prominent a rainpoint wifi scheduled automatic watering (drip) system was added. 10 gallons of water siphoned through the plants and into the basin floor overnight (triggered by first feeding / water-level of reservoir being above dripper/plant height). This was eventually fixed after a few more floods by adding a backflow valve connected to a tee valve on the output side heading towards the drippers. Now when the system turns off air is pulled from the one-way valve rather than the siphon starting. It's not pretty looking but it works.
The rainpoint will be tested to keep the critical boys making pollen for another couple weeks.
Once pollen is claimed we'll torture test them with the bloomspect ss2000 light (193W draw at 100%) by running 8" away at full power.
A dry-vac is an essential tool for indoor gardening when it comes to automated watering/drippers going bad or hydro from past experiences.
