Here is my screen after about 10 days. After letting it run for a few days here is what I have found. I am not sure if it was coincidence or not but I changed my second light from a 12 watt LED grow light to a 100 watt CFL and turned the flow down as low as it would go. After doing this I had growth almost the next day. I now have a 100 watt CFL on each side for 18 hours with low flow. When growth increases I will increase flow.
Also, i dont like the zip ties. They are wide enough that no matter how tight or loose I feel like they disrupt the flow and cause spraying and or dripping. I am going to look into another way of securing the screen. Maybe some thinner zip ties.
