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.
how far do you have the lights from the plants now and on what level? i have the same light and got some light stress from level 6 and having them to close.
Sorry, just saw this. I have had my lights up all the way to the top of the tent since I set it up. I've been using the phontone app to check the DLI and adjusting the intensity to the recommended par levels. The light was 29 inches away last week when I posted this. Since then the plants have grown a lot more. I'll measure light distance again this weekend, but I'm guessing right now the light is about 26-27 inches away now.
I turned my lights up to level 10 today because we are having a cold spell right now and the basement where the tent is is hard to keep warm.
