    DWC Root Slime Cure aka How to Breed Beneficial Microbes

    I was not trying for a scrog at all; the net is there to hold the plant upright. Without it, the net pot would just tip out of the lid of the reservoir. On my next grow, I'm going to switch to "lid style" net pots made for 5-gallon cans. The extra wide lid will give the plant more stability...

    Hi folks, I don't post her much but after what I've learned using this tea, I just had to share some pics. I'm currently on my third DWC grow. All three grows have been plagued with the brown slime and it was only until I discovered this thread when I figured out what I was dealing with and...

    Can I used distilled water in my DWC?

    You can buy RO water from Wal-Mart for less than 40 cents a gallon. Hard to beat that. I too run a DWC (5-gallons of water in a 10-gallon reservoir) and all I use is RO water.

    DWC PH issues: Ph dropping like a rock - Please help

    Too many times, I see folks saying that you must be pushing 1.2 or 1.4 EC in flower. However, I think this largely depends on the strain you're growing and how healthy the plant is to begin with. I know when I was pushing 1.2 EC, that's when I was getting a lot of leaf-tip burn. So I've cut...

    Well, since you inquired @churchhaze , here's what transpired since my last posting: 11/25/2017 - Lo and behold, it appears I must have had a bacterial problem all along.

    Good morning, folks. I thought I would post a quick update and say all is GOOD! After draining and refilling my reservoir yesterday morning, it was only a few hours until PH dropped to 5.6. Of course, my thoughts were, "Here we go again." But then when I checked my PH again last night prior...

    DWC PH issues: Ph dropping like a rock - Please help

    @70's natureboy - I'm pretty confident there is nothing wrong with my meters. Both my PH and PPM meters are made by BlueLab and are high-quality units. I just checked the calibration on my PH meter using GH 4.01 and 7.0 calibration fluids and my meter is spot on. I just changed out my...

    @rkymtnman - Going to the hydro store was a little disappointing actually. All they could tell me was what I already knew; Look for root rot, what kind of water are you using, what nutrients are you using, etc. They did offer to sell me a different brand of PH-Up, something a lot more...

    DWC PH issues: Ph dropping like a rock - Please help

    @70's natureboy - I've been dealing with this PH issue for weeks now. If you had read through the previous couple of pages, I just tried a 24-hour RO flush in which the PH remained relatively stable. We were trying a flush to see if that made any difference. After the flush, I started with...

    DWC PH issues: Ph dropping like a rock - Please help

    Thanks, @firsttimeARE . Bear in mind this reservoir water cycle used tap water with a PPM of 180. But I'm guessing after tomorrow's RO-water flush, best case scenario is I'd start with low nutrients anyway. I just took tonight's readings right before lights out. I'll be back in the morning...
