First grow

They have grown a ton and started flower. Air temps have been problematic over the last two days due to a snow storm we had over the weekend. I have a heater outside of the tent and it's keeping me around 72 with lights on and 64 with lights off. Changed and cleaned the resivoir this weekend and added canna boost accelerator. Only mixed up five gallons but they are very thirsty right now, so I may have to mix more before the end of the week. No signs of nute burn or deficiency. Lights are turned up to 10 vpd is set to 1.2. I will defoliate next weekend and may turn on the air domes.
