First Ever Grow!

We were worried about the humidity levels this week, and had to find a tiny dehumidifier. Where it would never go below 55 before, now it sits regularly in the 30-40 range, except just after watering. My ventilation has been 15 minutes pre hour, but I'm going to up that to 1/2 hour intervals to try to bring the temperature down. Lots of people helping with my question about when to harvest, consensus says likely about 4 weeks, maybe more. So continuing with the Bio-Bloom for the next couple weeks, and decide then. Also increasing nutrient from 1ml/l to 2ml/l, and watering 1.5 litres every other day.
