Ok good. I try to mist them twice a day. I'm on the way to the store now to get the 65watters but I was wondering if I should keep them further away or just use the hand method where if its too hot for my hand then they are too close?green stems are a good sign, means the plant is getting energy from the roots, so we know they are growing. make sure you mist the leaves at least once
cal-mag? And I try to keep the room at about 60-70% humitity but its hard to do with an exhaust ventThey look good! Perfectly normal. Watch your humidity and get it above 50% Consider misting with ph's water. It those leave continue to whiten on that one consider a little cal-mag.
That's about it. Ph is fine.
sure. im looking at selling all of my stuff. i have 2 ph controllers and a bubbleponics system and a whole bunch of other stuff taking up spaceYou wanna sell that auto ph kit? Stealth Hydro is backordered and I really want one.
well plants absorb the nutes in the water which makes the ph level rise. so for the most part you only need ph down. also changing the ph yourself you can make errors which will harm the plants. the controller constantly measures the ph level and changes it to stay in the optimum range all the time. it will also show when the pump is on so you can still monitor it yourself. so if it is on all the time you will see it and then you can fix the problem instead of checking the ph and it being way too high (which will kill the plants). the way i found best to use it though is set it to kick on when the ph reaches the maximum level and still change the ph manually. i would not suggest getting 2 of them though because they will conflict with each other. one will kick on and change the ph up/down then it would kick the other on to try to balance the ph out before it balances out to the right level in the tub. the system works great but i would suggest having the ph down tub not be very low because it takes a minute for the ph reading to change and shut off the pump resulting in too much solution. other than that it works greatMy thinking about the auto controller is that then you get used to it doing the work... and unless you have two so it will do ph up AND ph down automatically, its only doing half the work... so its not even fully automatic...
its a very cool system, but when you control the ph yourself I would think you know more about where your plants are at, and what they are doing... for example...
if something is constantly raising your ph, and the controller lowers it constantly, isn't it like treating the symptom but leaving whatever is causing the ph to go up? the real problem?(as well as filling your plants with ph down solution?) so you would kinda need to control it yourself I would think, to prevent more problems, but this is coming from someone who is about to start his first hydro gro, so its all speculation on my part...
