I recently changed to an automated system like I previously mentioned its an interval based system. I won a coupon code that gave me a pretty good discount off the system so I said why not. Its made by a company called Growtek USA based out of Washington State.
Prior I had been feeding once a day till about 20% runoff leaning on the higher side vs the under. I am using a local nutrient company and just following their schedule which in veg is 15 ml per gallon of each their Grow A and B. My starting water is coming from a
Hydro Logic Small Boy starting at 7 PH, 200 ppm and .49 EC.
After Foxfarms PH down and the 30 ML of nutrients per gallon my water is PH 5.5, 106 ppm, and 2.1 EC.
The fertigation system has been live for 4 days and all I do is add 2-4 drops of PH every day to maintain the 5.5 PH, but there has been feeding with some drift. I am still fine tuning the system but as of now I am feeding them 200ml of water every 2 hours.
I was lower but was not noticing any residual water in the drip trays so wanted to up it some to at least start to pool water knowing I am getting runoff. I know I should be allowing some dry back so might have to adjust but so far I am just holding my breath.
