    Bloom booster recommendations - DWC system?

    I rocked GH Trio on my last RDWC run and used GH Kool Bloom. Add it after Bloom. I don't know exactly what you mean by "increasing crop", but you might see density improve. Also, you want to use it at low rates, I believe I used less than 1ml/G.

    First Timer looking for advice.

    It sounds like you learned a valuable lesson in mixing RO and tap, I'm assuming you did that to try and cut down on wastewater, and as you found it turned it all into wastewater. No way of getting around the fact that in hydro you want to start with 0 ppm RO. I am not sure what your total draw...

    8 Plant 4x8 DIY RDWC Set up

    It's looking good! Do you clean up branches below the first net or let them ride out flower? I am a few days behind you in veg, flipping mine tomorrow. I am doing more cleanup this run since I had so many soft lower nugs where light did not penetrate. Also, if you ever decide to look for a new...

    RDWC Foaming Issue when Air pump is on

    I don’t see any film at the sites or in the res, and my pump is off temporarily to prevent the overflowing (screw gravity returns). Unfortunately I do see plenty of sediment in the bottom of the res and a few bits of roots. I should have gone with new hydroton for sure. I will have to do a res...

    RDWC Foaming Issue when Air pump is on

    That’s interesting. I’m wondering if it’s even possible for the H202 to have an affect since the hydroton was completely dried after the washing. I’m stumped. Maybe @Aqua Man has an idea

    RDWC Foaming Issue when Air pump is on

    I transplanted my second run into buckets yesterday and noticed some minor foaming last night. I woke up to about 3 gallons of water on the floor that bubbled over the lids, and when I returned from work today found another 10 or so gallons on the floor. Clearly this is not going to work itself...

    Hydroton Cleaning - First Grow Complete

    After going through the process and now having some foaming issues, I'd say screw the cleaning. It's cheap enough, you're probably always better off getting new and rinsing thoroughly rather than trying to clean all of the roots and salts without any problems and having that be worth your time.

    Hydroton Cleaning - First Grow Complete

    I just finished my first grow and I am looking for some reassurance on my hydroton cleaning technique. The hydroton dried out for 2 weeks, I have three 5 gallon buckets 3/4 full, and today I rinsed them with tap water, then added bleach, and agitated for a minute or so. I let that soak for a...

    First Ever Grow, 8-site RDWC, 5x9, LED

    Well, these plants turned out to be Sophie's Breathe and I yielded 20 oz on my first grow without any major issues, so I will call it a success. The plants grew tall and cost me light distribution and weight, but I recently raised the lights 5" by eliminating unnecessary hangers and will be...

    First Ever Grow, 8-site RDWC, 5x9, LED

    Flower Day 67 Started the flush day 65, straight RO water. I have to chop them down on day 70 or wait until the following Monday, and I think they'll be ready. I did not tuck and scrog like a planned to, instead, they grew through and used the trellis for support. A few colas that grew within...

    RDWC Circulation Issues...Any Advice?

    If you have leaking bulkheads you need to address the seal on the inside of the bucket. You can use a gasket if you have not tried that already. Like @Aqua Man said, it seems like you went 95% of the way on setting up the buckets with bulkheads but stopped at the res. If you add the bulkhead...

    First Ever Grow, 8-site RDWC, 5x9, LED

    @GreenFlowerer Thanks for checking in! These pictures were at the start of Week 7. I backed off to 1100 ppm then. Trichs have a ways to go, but I will start keeping a closer eye on them soon. So far everything has been smooth, I had a few thrips early on that probably came with the clones, but...

    Mold on stem/foam collar? DWC

    I’ll see what I can find on distilled vinegar. I figured maybe h202 as an alternative. I have adequate air movement above the canopy, enough that leaves and branches are slightly moving. However, the bucket system I have has drain lines too high and the water level was saturating the collar...

    Mold on stem/foam collar? DWC

    Noticed this white fuzzy-looking mold on two plants yesterday. Not much change overnight but I am going to change these 2" collars out for clean larger ones to help support the plants. Any suggestions for treating the mold before putting clean collars on?

    Brown film in RDWC res

    🤙 Thank you. The system I bought from Super Closet is designed terribly. The gravity fed return lines are almost at the lid of the buckets so any imperfection in leveling and the water level is up to the top of the hydroton, probably the massive source of light leak causing this. SMH. I should...

    Brown film in RDWC res

    I did a res change 5 days ago. I am using RO, GH trio +calmag and si, and hydroguard. The first few days the res was clear, but today I found this film floating around in the res and on the pump filter. Can I get some help identifying this, and whether there is anything to do besides a res change?

    Day 21: Roots in the cloner 2 days before transplanting. 12/12 rooted. Day 23: Transplanted 8 of the healthiest plants to buckets. Filled the system with 55 gallons of RO and fed with Si, CalMag, Micro, Gro, Bloom, Hydroguard, in that order. Room: 76 deg/ 80% rh Water: 500 ppm, 71 deg, 5.6...
