I'm in an uninsulated shed and the temps have been single digits so overheating has been no issue. I have an electric base board heater set at 65. The canopy stays around 70-75.
It's now on day 27 and far bigger than the other plants were at that age. I've noticed the autos can be hit or miss. This plant and another germinated the same day, but the other only grew it's first set of pointed leaves then just stopped. It has since started growing again. The big plant 12...
It's 21 days old now and going great but some yellowing on the lower fan leaves and tips of new growth. My other 2 plants aren't doing it with all the same ffhf dirt.
Being a welder, I have very easy access to bottles but was wondering about the other parts I would need like the timer and electric switch for the gas flow seems expensive.
