Glookies by Barney's Farm - Hydro 3x3

Hi! This is my first ever indoor grow, and I decided to go with a hydro top feed setup. I am using a 3x3 vivosun tent with a powersun 250w HPS lights and 4" exhaust fan. I started the seed directly into the rockwool and put the rockwool into my pots 4 days later. I had to fight down my PH for the first few days but it's much more stable now. I am using the Canna Aqua line of nutes, and had just introduced the Cannazym a days ago and the growth over the night was phenomenal. I had set the plants 18" apart on the furthest and they were already starting to show sign of light deprivation after 4 days so I made a new lid with the pots closer. They are now at 11" at the furthest and I moved my light 90* to get a better reflector coverage. I might switch back to the other lid for flowering but right now I am aiming on growing them straight and strong. Planning on topping 3 times and aim for 8 head per plants. My lower controller is cycling on and off the humidifier. The other 2 controller are hooked to the exhaust fan and will start it at maximum speed if the temperature inside the tent reach over 79* or if the RH goes over 60%. The later might be more useful on the flowering stage but having it automated give me a peace of mind that the growing environment is stable. Otherwise the fan run at about 50% of it's capacity. This is such a big learning curve with so many things to know but at the same time it's a lot of fun.
