A quick update:
We transplanted 6 plants that were in 5 gallon pots into 10 gallon pots. Theye were only in the 5's for 9 days yet the roots were packed in pretty tight. We're using a coco/perilite mix.

We're running a couple different kinds of halides to see what works best for us. The Hortilux Daylight Blue gives the tightest node spacing. The Sun Pulse Pulse Start 6.4k is a little brighter and penetrates deeper into the canopy for a little "thicker" growth. I'm thinking of using the Daylights early on, when the plant is small to really pack the nodes in, then moving them under the Pulse Starts for the rest of the veg time.
I'm using Digilux HPS. They're brighter than the Hortilux HPS and were designed for digital ballasts. I have 6 Hortilux's from a previous grow and may use them for our bare hanging bulb experiment.
None of these bulbs are cheap. In fact, they're pretty much the most expensive bulbs out there. However, if they give us just 5% better growth than a cheap bulb, theye pay for themselves many times over. I just can't see skimping on lamps in an indoor grow.

We put in a little 10,000 btu AC unit a few days ago. The exhaust ducting is plumbed into our main exhaust lighting manifold. This provides strong negative pressure where thr AC's exhasut hose ties into our 20' ducting run. I've found that the better these units can "breath" the better they work by far.

The humidity has been quite low here. The new air conditioner doesn't help either. Here's a pick of our evaporative cooler and our little humidifier. When alls said and done, we'll need several of each.

Several 6" vent holes are provided to facilitate air flow from the veg room to the flower room. The 36" attached ducting acts as a light block between the rooms.

That's it for today. We'll put up a couple lights tomorrow to try and keep up with the explosive growth we're experiencing. Maybe we'll knock off early and try out the collective's new hash glass. Yipeeeee.
