Thanks for all your replies. I will keep them alive at least until Saturday. I don't have new seeds yet, and maybe I will keep them and take it as a learning run. Yea, I am not sure about the whole thing either. I have no experience with autos, so I am not quite sure if they will just flower a...

This is true yea, bur I should figure out what caused it before I start over. Could it be that the air pump is too strong?

Yes at first. Maybe too little tho. This could be a reason that they grow so bad but since the roots are in the water it shouldn't be necesarry anymore right? Next time I will add a drip ring with a timer and let it flush one to two times a day for about 15 minutes until a root base has formed...

I added a little bit of CalMg, about 30 ppm. My tap water has around 40 ppm calcium and 15 ppm magnesium. I have my lights on during the night from 19:00 to 13:00. This keeps the temperature pretty stable. Could it be that the nutes are too old? I always thought mineral nutrients can't go bad...

I am using a very strong air pump with 6 air stones in the reservoir (20 gallons of water / 10 gallons of air per minute) and I left a 2 inch air gap, so aeration should be fine. The temperature is in the optimal range of 68 °F. I did not remove chlorine, since my tap water has almost no...

I think I will wait until Saturday and see how they do. Do you think they had too little nutrients? I am also considering bad genetics, but I killed 5 out of 8 so far. I don't know if 420 FastBuds is a bad breeder or am just a terrible grower, at least in DWC. Do you spot any issue with my...

Hey guys, I really could need some advice. This is my third attempt on DWC (first 3 plants died of too little water, next 2 of drowning in too much water). Currently, I have 3 Autos in my DIY DWC setup. Two of them are two weeks old, and the third one is the survivor of the second attempt...

Since I have to add about 12ml bleach to get around 3 ppm and the bleach consists of 2.8% sodium hypochlorite and 5% sodium carbonate, let us assume we have 8% sodium residue of the 12ml solution. this would be about 1g of sodium. this would result in 1g in 100liter which is the equivalent of...

I mean it is basically baking soda but I have no idea... Yea maybe someone can help me with a little more chemical knowledge =)

i cant buy pool shock at my location, is the sodium carbonate a problem?

Hey, I can't find bleach with only Sodium Hypochlorite. The unscented one still contains Sodium Carbonate. Is this a problem if I keep my nutrient solution sterile with it?

ok i will make sure to keep it under 5 ppm

because of the plants or because of my health? yea i'd start with 5ppm like 2 days before i plant them into the netpots and then add 3 ppm weekly to keep the bacteria away btw is there a list of the optimal amounts of nutrients cannabis needs with R/O water in hydro?

what was it haha?

Yea I thought about that too, it's about 2%. I have no chemistry knowledge tho, I am an engineer so I am very careful about things I dont know. Thanks for the reply!

I am using normal bleach with 2.8g sodium hypochlorite at 100gramm. Ammonia is in the GHE FloraGrow (Ammoniacal Nitrogen).

really, i thought they do with ammonia?

So, as far as you guys tell me, there should be no problem to make a bleach batch with like 500ppm and add 1 liter of it my 100 liter nutrient solution to achieve 5ppm. my base chloride ppm is almost 0 btw. No worries of gas right? Is there a right order to add the nutrients/bleach? I am using...

Hey, soon I want to start my first DWC grow. I have read that people lr use bleach to keep their nutrient solution sterile and I find that a cool way. My only worry is that if I add the diluted bleach water mixture to the nutrient solution, the bleach might react with the fertilizer in the rez...

Hello, I am new to this forum but I am active in other grow forums. I want to ask here because I saw a lot of posts about this topic. I've done my research and read through many posts, articles and so on regarding hypochlorites, hypochlorous acid, ozon, h2o2 and some more for keeping a...
