First grow in ten years.

Tricky to keep the peat pellets moist but not soaked during this week. I submerged the peat pellets in some slightly pHed down tap water. Tap is almost 8.5pH. I didn't have replacement probes for my decades old Hanna meters, but I do now. The pen from Hanna was accurate enough that it didn't need replaced after nearly a decade in storage. Props to Hanna. The grow room and RDWC hydro setup are compete enough to add the girls! The room is nearly 4'x4'x8'. The air pump is a 70lpm going to 7 air stones that are 4"x2" cylinders. Air pump is enclosed in a bin filled with rock wool and fiberglass insulation with tubes protruding the enclosure. Once this was completed the pump was moved outside the grow room. The 600w metal halide bulb is about 25” from the nearest plant. It's actually a conversion bulb putting out 50k lumens when new. I haven't used this much since it's the MH bulb and I don't spend much time in veg. At more than a decade old with slight use, it needs replaced. Lights were on 24/7 until I could replace a broken grounded timer. Plants tolerated the transition to their new home well.
