    GH Trio RO and mag deficiency...

    IMO if your using R.O. just count on always using calimagic all the time. Treat it like they are married. Not a lot but like 1ml a gallon or whatever to get you to .2ec. If you notice nitrogen issues drop the grow a bit. I would profess my love for GH Three part and calmag but I will spare you...

    Using food grade H202 (35%) in hydro reservoir

    Damn that is a lot of peroxide. I used 120ml/20 gal and burnt my roots off. Literally wiped what was left off the sides of the netpot. They made it through though, somehow. I have heard professional greenhouses often use chlorine in some form. UC Roots is supposed to be PH stabilized hypochlorus...

    5by5's 2nd RDWC grow

    I decided to let these go good and long. Make sure sure they are finished, I felt like I harvested early last year so.... My PH has been taking shits down to 4.9 or so the last few days. I have been dumping a lot of PH UP in there. No root rot or anything, I just think my system volume is too...

    5by5's 2nd RDWC grow

    Nah, completely different than my first grow. It was me, not the strains. I was sloppy. Had I handled them appropriately the result would have been much different.

    5by5's 2nd RDWC grow

    I use GH Three part. My last mix was about 1ml calmag/1.5ml micro/3ml bloom per gallon.

    Sick of Root Rot can I convert my RDWC to some other system?

    Nice recovery! I like how you cleared out the lower for good airflow. It will mean a lot when the buds are massive.

    5by5's 2nd RDWC grow

    For some reason the red hairs dont show up against the intense light of the LEC. Ohwell. Notice its gotten nice and chilly in there. RH is 40% max when it rains outside but usually stays near 30%. I will not grow different strains in a rdwc again. It's not a big deal balancing the nutrients to...

    Is this mold?

    That's spider mite damage, and quite an infestation by the looks of it. You need to be better at spotting that before it gets out of control like it has. If you don't get rid of them soon and I mean soon, your plants are going to be fucked. Spray with mighty wash and hang up a "no pest strip"...

    PH 5.7-4.7 in 12 hours. DWC

    Yeah, what your water level did in that time in relation to your readings is the key to understanding what you are seeing.

    are there any stores that carry bulkheads?

    Sigh...dunno where you are from but 'round here that is called a "chase".

    are there any stores that carry bulkheads?

    LOL TF are you talking about? He is building a dwc, not a boat or airplane. Did you forget you were in the hydroponics section of a pot growing website? Home Depot. They are like 20 bucks there though, but they are the good heavy duty ones with the thick double rubber gaskets. Everbuilt is the...

    RDWC Mold?

    Is that what you are using now? That GH chart you posted awhile back has done me so right.

    RDWC Mold?

    I have no idea what all that nutrient stuff is or if any of it is organic. It may just be mineral salt or organic residue. I used rapid rooters.....they grew mold, and then my seeds damped off. My experience with anything other than plants growing on the rooter did not end well. What do the...

    5by5's 2nd RDWC grow

    About halfway into week 5 and I am starting to see a red hair here and there. All looks well. PH is dropping this year just like last year, but its not tanking low or anything. 6.0 to 5.6 in 24 hours. I don't think its abnormal. I could get better at canopy management though. PPMs are around 470.

    dwc water level?

    I will say this. The lower you run your water level, the thicker the feeder roots leading to the main rootball will be. Seems if you run it higher, you will get more root mass, rather than having long thick feeder roots leading to it.

    How much h202 to kill fungus gnat larvae?

    Shrubber is dead on about the H202. I found out the hard way. I once used 120ml/20gal of 35% which is about 6ml per gallon trying to clean my system when I got the slime. Holy shit......you ever watched your girlfriend use Nair, and wipe all the hair off her leg?? Thats what it did to the roots...
