Sounds like an operating room or the nuclear clean area on a submarine. I’m gonna start calling you doctor hippy. I am careful not to tend to the plants after being in the yard but I don’t have a grow room only two tents which are both located inside my house. As tiny as those little bugs are they could have slipped them the screen covering at the bottom of the tent or of course found their way in thru me or my tools somehow… I did use organic soil this time and may have brought them to my tent that way. I did a full sterilization including vent fans filters tent tools just prior to putting my four plants in to flower so I don’t think it was that. hope to find dead thrips on the blue and yellow sticky’s when I check them later. This morning, couldn’t find any. I guess that’s good they have calmed down at least but I will be in there “Maybe naked like Big since I can’t get burnt on the belly with a hanging bulb”I designed my grow room to need a minimum of my interaction. You open a solid wood door and find another door with a 2.5'x5' plexiglass door. I can view the plants without ever needing to expose them to the outside world. If I need to get hands on with them, I go straight from the shower to a clean pair of scrubs. The only time I need to go in the room is to tuck the tops under the hog pen screen during veg or to harvest.
The nutes and water tests are done remotely with the reserve tank outside the room. The CO2 is also outside. I try and make things dummy proof 'cause.....well...... you know.
I love RDWC growing. Only bugs I ever had were the gnats, and that's not in the grow room, but the clone/early veg area.
