Grapey Walter! 3rd grow

Tied the main cola down at the start of the week. Thought it might be too late but she seems to be responding well. Day 38: Top dressed with 8g of sulphate of potash Struggling to keep the temp and humidity down it was hitting 29c. Dehumidifier reduced the humidity from 65 to 55%. Day 40: Bought a CO2 monitor. Only venting into my room atm. With the window partially shut and me in the room CO2 is 1000+ ppm so reduced the height to 12 inches, approximately 700 ppfd which equals 45.36 daily light integral (DLI). When i'm not in will increase the light height to aprox 500 ppfd (32.4 DLI).
