Well I have some more work done on the system. I got the light system set up on it. It is 2 dual T8 4ft flourescents. I have 2 5000k
bulbs and 2 6500k bulbs.
For more than 10k lumens in a 4ft by 14" area. That should be plenty of light for some lettuce. If need be I can fix mount another fixture in the back, but I don't think I will need to.You can also see how I fixed it to the frame. It currently has 4 pullies and if you pull on the center loop it goes up evenly. I will be adding another line and making a 'reel' (like a fishing one) to let me control the light levels. It sits about 1" from the rails when completely lowered, and about 1' when wrapped as it is in the picture. (the retaining strings slid onto the hooks for the pullies)
I am still waiting for the ordered supplies to get in to let me test the
pump to see what I have to do. I have multiple lines set up to let me do a drip feed, semi
aeroponics, small sprayers..... tons of things to test to let the roots develope down into the NFT.
I hope it all gets here soon.. I started germinating the lettuce to try to be ready for when things get here... of the 10
seeds I set. 8 have already sprouted (2 days). 8/10 is pretty impressive in 2 days. I hope that those plants are still going when the supplies get here.
