so.. the res is 8 gallons. I run my timer 20 seconds on, 15 minutes off, no mold issues. you shouldnt have mold no matter the cycle time, especially if you're dosing with H2O2. I'm going to assume that you've already cleaned everything EXTENSIVELY with hydrogen peroxide solution and put...

heaths vertical tube grow is NFT, not DWC... at least I think that's how I remember it. I dont think a pump just moving water around would work, there are some pumps that have an airline attached that will pull air from outside the res and infuse it into the water. I think that would work...

I use small pots that are slightly smaller than your grow bags. Instead of using a big rockwool cube, I use a 50/50 mixture of rockwool flock (mini cubes can be used just as easily) and hydroton. You can germinate a seed in 1" rockwool cube, and once roots are slappin out of the cubey, then...

Refrain from bleach. Run to a pool supply place and get some hydrogen peroxide, should get a gallon for around 20 dollars. use the H2O2 (mixed with water at the proper ratios of course) to clean the res and, you can also dose your res with the H202 (again, proper ratio per gallon) and you...

love the cheney avatar... I got an RO system and used it for about a month, then scrapped it. I now use the RO as drinking water and just run 300 ppm tap. SO much easier to fill reserviors with just a garden hose. but I have more than one res. If I only had one res, I'd use RO. still...

any roots that come out of the bottom of the pot will get "air pruned" you'll likely never notice them. If you use a mat, then you'll probably not be able to move your pots around to arrange your plants so they all get better light. I use 50/50 hydroton and rockwool mini cubes, and flood...

......... as if.

I use a mini split ductless system like in the link below, but I have an 1800 BTU w/ inverter (important for energy savings)...

I read your journal after this thread. Great journal by the way. I hate those kind of ACs... they take up floorspace, and the exhaust tube is usually hot to the touch. I ran one once, and insulated the exhaust, but it was kind of a pain in the but. I live in california, so it's not often...

I dont have a scientific routine, every 3 days or so I just dose it with 30-40 ml of H2O2. seems to work fine. I was using Oxyblast, which is 10% hydrogen peroxide, but just switched to some product I got at a pool supply place local (so i dont have to pay shipping anymore) that is 27%...

seal the room, run an AC (I strongly suggest a mini split unit) your CO2 will stay in the room, no need to vent inside air out, or outside in. just use outside air to go through your lights to cool them, then exhaust that air back outside. For odor in the room just get a can filter, and...

How could it hurt? Throw it in! These plants aren't that delicate homie. by the way... Get those girls in flower!!!! getting toooooooooo tallllllllll.:eyesmoke:

Add clonex BEFORE you get roots. I dont get any of the smellyness from the clonex that you mentioned. I just use straight tap water (@ 260 or so ppms), clonex, and H2O2. the soup stays clean.

NO, please believe, this is a bad idea.

I use simple green to clean it... but........... I DO hate scrubbing it. are you saying there are less nute salt buildup with house and garden? I demand super simplicity slash cheapness when I feed my glistening whores. is H&G chem or organic? I needs to do my homeworks.:idea:

non issue with flood and drain. if I ever switch, I think all this talk about house and garden has me sold. :bigjoint:

be very very thankful that it's not Pythium... because pythium is a horrible mess to contend with. I loves me some GH chem nutes! white roots, end of story (not that I can see them :) )

I'm not even sure it's root rot. Res temps are too high, but that doesnt ensure root rot. probability goes up for sure. I've dealt EXTENSIVELY with root rot back in my old DWC and Aero/NFT days. Roots will have a slime to them. If you dont have slime, or some sort of viscous shit on...

Does anyone else besides me think that drip systems clog too easily with nutrient salts? I considered drip and coco, but opted for flood/drain because of the clogged up dripper thing. with flood and drain, the only real problem that I find is pump failure, BUT, I have never had a pump...
