Started a new grow about a week ago. I have a 4'x4'x7' grow tent with a 1000w ballast dimmed to 750w right now. There is a 400CFM inline fan dedicated to moving air through the cool tube. There will be another fan attached to a carbon filter but that arrives Thursday and its 410CFM.
I have each plant in a 5 gallon bucket and they are all connected to a central reservoir with the total coming out to 30 gallons. This is a mix of a dwc and a aeroponic buckets, it has sprayers and the water that sits bellow is constantly receiving new oxygen rich water. The water I use is from a portable ro filter so there is nothing in it initially. I have been able to keep the pH at a stable 5.6-5.7 and the water is 200ppm. I have been feeding them sensi 2 part grow at 1/4 strength and will be using Cal+ with the next water change.
I am running the lights 24 hours a day until the plants have all sprouted and have a few nodes then I will back it down to 20/4 or 18/6 I have not decided yet. Due to the lack of a internal fan I am running a bit hot about 77-84 degrees and 25-30 humidity.
The plants from front to back on the left; left back has a White Widow Feminized, left front has Crystal Fem, middle back has WWF, front middle has WWF, right back has G13 Haze Fem, and the right front has G13 Haze Fem.
I am looking forward to this grow and any followers who want to help me along are more than welcome .
