Passion #1 + ICE & Cream auto - my Landlord and me outdoor

Nothing interesting with the plants. They are still thin and sluggish. I felt, that the stretch was to strong and they should get more light. They are under 16/8 400W MH right now. Usually I do 18/6 with this setup, but I dont want to give them to much light hours now. In the beginning of May, the days are 15-15,5 hours long and I dont want the Passion #1 to flower, because they get less light, than before. We began to surround the plant holes with terra cotta tiles, we found in a corner of the garden. There are plenty of them, I hope enough for all the holes. We put a Microdrip system in place for easy watering. We are still cleaning around the planting area. I cut a couple of tree branches today, that were stealing light in the earlier hours of the day. I set up a camera and will be doing a 48h time lapse of the planting area, starting tonight at 00.00. I want to see, if I have to cut more branches or bushes further back. If it works, I'll post the time lapse. Edit: I added the timelapse test.
