Baby Blue My First Grow

So they are growing well. Getting all their little Leaves as expected. Was getting leggy so I lowered the light for a bit but seemed too close as it grew so I raised it Again and doing fine. Greenhouse is getting hot in the days. 102 today with low humidity 10% I ordered a mesh sun block to cover 80% of green house. Hopefully cool down on afternoon sun time. Added another fan. So I have a window fan and a oscalating fan. Pay close attention and regularly mist pretty dry this morning but no drooping until late afternoon and then I gave them all a good soak with a little kangaroot mixed in. I read kelp is good for hot roots so.... hopefully they were right. Small doses. Tsp/gallon. Decided to start another blueberry auto as one didn’t germinate. Gave up on it and planted another. Hopefully next few day’s will be cooler. That greenhouse is scorching hot. Hope these babies like it. I added a water tray between the pots and it all evaporated noticed my humidity was up to 40% makes me feel a bit better. But leaves look good. Not burnt or bending. Keep on keeping on with my first grow!
