Ok sweet, im glad I brought it up. I haven't used since there was first sign of hair BUT I was planning on spraying tonight so I'm happy I brought it up and I'll just stick to what I've been doing. Keep watering, keep feeding and keep spinning the plants 180° every 3 days or so. Also I'm using a perforated hose for co2, right now in bouncing back and fourth from running the hose through the stalks and running it over the tops of the bushes...... what do you think? Co2 is heavier than air right? So probably on top but dug in a little bit??
