Jollybud's Greenhouse

These plants were clones that were vegged for 2 weeks before I got them. They were then transplanted immediately from 1 gallon pots to 7gal pots with FFOF. We are currently getting about 10 hours of sunlight in my region. Supplemental lighting is set too a 12-12 schedule. I will start a light feeding regiment next week using Alaska fish emulsions(both veg and bloom) and a weekly dose of recharge. This is my first run with this setup so I will be experimenting on timing of feeds, light height and irrigation schedule a lot so any suggestions are welcome. I still need to install a fan inside the greenhouse to help with air circulation. I have my exhaust fan set up with an existing temperature controller until I buy a humidity controller for it. I also have a heater but since my exhaust fan is hooked up too the temperature controls I will not be using the heater until I absolutely need it or I get the exhaust hooked up to a separate controller. My main stress right now is getting the drip irrigation set up right. I currently have it set up too water for 3m every hour but I can't turn it off at night and my Humidity is spiking. I am worried about mold. If anyone has any suggestions on how to set up this drip system so its not watering at night or even ideas on how too optimize please let me know.
