buy a chlorine pool test kit. Reach 0.5-1 ppm every day. In practice, this means putting few drops of bleach once a day. I did this and it worked, no more pythium.. i can go without changing reservoir for weeks and water smells like first day. The only con is you have to put it every day, or...

Hi folks, I'am on week 6 of flowering, and imho, the process is apparently going a little slow. It is a Original Amnesia from dinafem, strong sativa, so it can possible be just a matter of the strain.. Other info: 12x CXB 3590 @50W Dwc 4x4 tent I see revegging symptoms (single point odd...

i keep mine from 300 up to 700. If higher than that, my lady gets burnt

I did a big shock of chlorine...pH got stable and now is going up as usual. Think im gonna aim for 5 ppm every get 4 days and see what happens.

Hello guys Tap Water with 5 micron, carbon & uv filtered Water Temp is 18°C, ppm 350-450 I have 1 plant, 3 weeks in veg. I suspect i have bacterial activity in my roots. I changed the water 2 days ago after I saw ph was 4.7. Change water, set the ph to 6.1 w/ 2ppm chlorine and now is 5.4 and...

You can improve the canopy coverage... Tight the net scrog LST Topping on younger plants ( right)

Last grow i had serious root rot problem, ph went down to 4.8 few hours after a water change

looks root rot, if it were the nutrients all the roots would look the same. However, it just affected a small portion of the roots...

Did you DWC with those temperatures? how was it? do you go sterile or bennies?

Mainly due to the nutrients fact you named. It is way to impractical, if not impossible to compensate the nutrients broken by the UV. How can you estimate how much nutrients were lost.... I don't want to complicate things. Edit: I just seen that product "ionic UV balance", I live in a third...

Here in summer, temperatures can go es high as 90°F + pumps + light heat.... waterfall is just nothing

How do you know you are not stacking by manual dosing? i read measuring free chlorine with our ph range is impossible. Anyway, i will set the autodoser to pump 1ppm twice a week and check the roots every now and again.

Hey, RFFT, how did the chlorine work out?

Hello guys. This is my third run with RDWC, and now im paying more attention to details i haven't in the previous ones, like trying to keep my roots white. I choose sterile cause i made an automatic nutes feeding system with arduino and peristaltic pumps. So i just basically do nothing more...

Yes, slowly and carefully. You can even tie the top down to the ground. Remember in flowering the plant can double its height..

Yeah, just seal the leaks and 12/12, if the plant is too tall just bend it

Yep, your plant is reveging, you might have light leaks

actually i have spider mites, but i already took care of it... my point was the lights, thanks anyway.

Lol, I had the same idea DIY with PVC tubes, it is easy and cheap
