Was planning to harvest in stages, remember I pollinated a few branches, so will have to give a bit more time for those to mature, also giving a chance to the underdeveloped lower buds which will be exposed when I harvest the upper colas. Will start in 2 weeks or so.
Humidity is quite high, I have my extractor on a timer to kick in for 10mins every hour, which purges and replenishes the environment with cool dry air. My tent maintains a strong negative pressure, walls suck in, when then extractor runs, seems to be adequate control as the environment is quite dynamic, seems to work as I have not had any bug or mould issues, touch wood.
