Since my bloom-tent will be occupied a bit longer, I decided to slow everything down by lowering the DLI to 12. Thus, I'm keeping VPD at 0.8 a bit longer (leaf surface temperature is 25°C/77°F, resulting in target RH 75%). Plants will therefore also need less water.
Besides that, the babys are looking happy and healthy. One stretched a little bit more so I bended a piece of wire for here to hold on.
Also, everything is water only. I'm using plain tap water without pH-ing anything.
