I use a soil moisture meter to determine when to water. comments are always welcome.
Squish,
I am planning my first grow with a Dark Room. I have found your journal very helpful. Thanks so much for the great info and pics.
How do you have the room ventilated? Can we see some pics of the lights, filter and fans?
Yeah, BGH can take their time occasionally. I'll get some more detailed pics of the lights and ventilation today.
