So im doing my first hydroponics grow with a DWC system. Everything is growing great and i'm in my 3rd week of flowering. I've been changing the water every two weeks or so and adjusting the ph weekly. My plants are a little taller than 3 feet now and last time I changed my water the plants started falling over. It seems like the walls were supporting them and when I took the lid off my dwc system they just collapsed. I fixed them up by using some tape to keep them from falling over and that seemed to work but I'm going to have to take the lid off at least 3 or 4 more times. Anyone have the same problem? How do you handle changing water when your plants start getting big?
