One data point about hydroponics. The 4 tomato plants in the photo were started late February in 3X3 rock wool blocks.
On March 6th the 2 on the right were transferred to a hydroponics setup and the 2 on the left were put into an enclosed frame indoors. Both were under LED lights. Humidity around the hydroponics is about 40% and temperatures range from 60 to 70. Humidity in the enclosed frame is close to 100% and temperatures range from 60 to 70.
The 2 on the left were actually starting to fail so I potted them up today. The 2 on the right were getting to large and starting to spread and the rightmost one appeared to be wilting so I potted them up today.
They are now in the daily shuffle of plants out into the sun on warm days.
