First Time Growing Anything

Things are starting to take off now! I've transplanted into a mix of 3 and 5 gallon pots, just wanted to see how much difference there would be when it's all said and done. Plants are now in their grow room under a Mars Hydro SP3000. I'm shooting for a PPFD of around 800-900. I'm watering a pint a day and still not seeing any runoff to speak of. I'm planning to start increasing that amount and getting shifted over to watering every other day. The purchase of the week this week was an IR Thermometer. I spent a few days before transplanting trying to get the grow room temperature and rH dialed in and in the process I fell into the rathole of trying to figure out what is really meant by room temperature vs canopy temperature directly under the lights vs leaf surface temperature. By nature, I'm inclined to overthink everything and clearly growing cannabis is not going to be an exception to that! Maybe smoking some cannabis will take the edge off my tendency to obsess :) With all that said, being able to shoot leaf surface temperatures with an IR thermometer is pretty cool and allows for being able to calculate Vapor Pressure Deficit which will provide some insight into how efficiently the plants can undergo transpiration.
