Edit from 19th May. Literally 00:09 Pre-Flowering. Fat Banana looks like Hermie. Royal Critical = clean pre-flower. Edit from 19th May. 16:26 Fat Banana had balls sack and pistils growing all over the place. I nuked everything that had balls on it. I left only top node with pistils. Royal Critical is full of pistils, no balls. Now I wish I had photoperiod seeds instead of automatics. I would give Critical 1 extra week in veg. She is around 10-15cm smaller then Fat Banana. I switched the lights back to 400W. Edit from 20th May. 14:45 I think 32C is maximum what these plants can handle. With 600W I was reaching 34C on some top leaves and that could possibly turn the Fat Banana into hermit (she was the tallest). I open the tent a little (front doors), I put big-ass fan on second gear blowing strong wind through the mesh-window of a tent. I put the lights straight up to the ceiling, I literally can't put them any higher. Fat banana is now 58cm tall and around 80cm away from the light. Royal Critical is now 41cm tall and around 100cm away from the light. 50% Humidity 28C under the canopy/on the ground under the leaves 31C Air temperature. Fat Banana fan leaves temperature: 28.5C Fat Banana center/middle of the plant: 30.9C Royal Critical fan leaves temperature: 27.5C Royal Critical center/middle of the plant: 27.8C NOTE: Royal Critical ugly/yellow leaves have higher temp: 29-30C The rest of small plants range from 28 and 32C Surface area/soil temperature DRY: 35C Surface/Soil temp. WET/SHADOW: 28-29C That pistol/laser for checking temps was solid purchase. I can see back of my tent is more hot then other areas. Will do more Temp-Checks in the future. I also deleted few things from "Condition" tab because one day they are correct, the other something change and the info is not accurate anymore. I'll update info here in edits. ~~~~~~~~~~~~~~~~~~~~ Farm Control Sheet Date: 20th May 2024 Time: 16:57 Tent status: Side doors little bit open. Both windows fully open.
