At week 1, plants are doing well. I'm seeing a lot of growth, but there is one small patch of HC that is a bit yellow. Not sure if that means I need to start adding more fertilizer to the misting water.
I also received the glass intake tube. I was a bit alarmed when I initially retrieved it from my mailbox, because it's just in a standard envelope that looked badly beaten up, and the contents felt like it was just wrapped in one layer of bubble wrap! However, when I opened up the envelope, I realized that the glass tube was slipped into a piece of PVC pipe, then wrapped in bubble wrap...pretty sturdy and ingenious way of shipping it securely. the tube itself looks exactly like a test tube, but clearly he has some machinery to cut the slots that allow it to suck in water. Very clever. Installing was easy, but it cracked the plastic connector a bit. Whereas the original plastic intake tube connects to the other piece from the outside, the glass tube fits inside the connector (if that makes sense). I didn't apply much pressure, but it cracked the adjoining plastic. I don't think this crack will continue up the rest of the plastic, but I may need to order a replacement piece just in case. In the picture, you'll have to look pretty closely to see the small crack in the plastic. Overall, I'm happy with how transparent it looks in the backdrop. It blends in way better than the smokey gray plastic intake tube, and I feel that once I flood it with water, it will be nearly invisible. I'm a little worried that somehow the glass tube will eventually disconnect from the plastic intake and hit the adjacent rock and crack since it's only held in there by pressure. Before I received it, I was thinking that I may get some kind of silicone gasket to make a more secure seal, but now I know that there's not any tolerance in there for anything like that.
