The best thing to do.....in my personal opiinion only.....is to buy an mh conversion bulb for your hps ballast and use that during veg. Flouros WILL be cheaper but I personally have not been happy with them for vegging my plants. It will be more expensive to go with hps AND flouros but mh lighting is PERFECT for vegging and your plants will thank you by growing bigger and better for it with just one ballast.
Weedhound Reviewed by Weedhound on . Ph is rising, can't seem to stabilize For the past 36 hours now I have had my clones in my aeroponic system. For the first 12-14 hours or so I did not have any meters yet and so the ph was around 8.6 and the ppm around 400. I have been keeping the ph between 5.2-5.8 but in the past 6 hours it rose to 6.7! I have been reading my eyes out of my skull it seems and I have found that my filter mounted on my tap might be contributing to a high ph due to the water softening process, so I have put a gallon of tap water plus 5ml / Rating: 5
