I have seen 1m2, fully scrogged, Flood'n'drain, drink 40L in a week. But I am still learning and my results are often lower, maybe 20L a week for 1m2 (3" x 3").

Scrogged at 1m2. If that is true, then flood and drain would be, for sure, less? With "tainted" water returning to res, the flood and drain res must get worse faster than water that does not circulate. I haven't had to touch PH/UP down once it is set. I think this disbalance is what I am...

Hi guys, I run a flood and drain systems, with 100gal res's that I change every 2 weeks. Recently, in a veg tent, I have seen slow/miscolored growth towards the end of a 2 week cycle (with E.C and PH are fine). I feel like I need to drop the res change frequency to every 10 days and see if this...

Thnx :) Sweet, air stones are on their way out!

Thanks for the response :) Do you have a source or further reading to find out more about this? I had a google and could not find much :/

OH Interesting, I might be better off removing them then? I might have save the blowers for a DWC grow down the line.

Yeah this seems correct to me haha, I think I got too excited and decided to throw some air stone in there. I like the airstones to help mix the solution when I am making a batch up, so I will probably leave them for now.

Awesome :) will run 3ppm and go from there. Thanks for response. Is the 50% you have added not the 65% I have used in the calculation? Excuse my misunderstanding, but isn't all Calcium Hypochorite free chorline untill it reacts with something in the water?

Legend. 5ppm = 5mg/L 100L = 500mg Account for 65% strength. 500/.65 = 769mg. Is this the correct calculation method? I might start around .5g per 100L and see where that takes me.

I am running sterile. Was using some humics for a while, but things got nastey and started using H2O2 and only salts now. I have problems due the opacity on my buckets, I have to wrap them in garbage bags to keep light out. If you don't have light problems bennies might work for you.

Hi guys, I am running 100L reseviors, sterile, using 35% H2O2 @ 1.5m/L twice a week, for the past few months. Moving to Calcium Hypochlorite to reduce costs. Using this calculator https://handymath.com/cgi-bin/chlorined4.cgi To get 5ppm of Chlorine into 100L of water, using 65% available...

Hi guys, I am running flood and drain with 100L (26 gallon) reseviors. I have airstones in all my reseviors. But reading up recently there is a lot of debate about wether this is a good idea (introduces airborne pathogrens and other nasties). Should I stop doing this? Is a move to small...

I have tried a bubbler, but not with air stone, just air tube. No success, I do want to try this method, as well as having a water pump with air in take (Venturi or something). did you have problems with other methods before using this one?

Tribus are benies? Or more like a rhizotonic? I might try some rhizo with no h2o2 for science.

Thanks for info, well the lack of light is not the problem then. Mine get basically the same light levels. What is with the clear plastic barrier around the side of the cloner?

I am not sure about infestation, I have not sprayed for a while so will begin a preventative mesaure till I can clone again. I used a combination of l Tau-fluvalinate based insecticide and Neem oil. I have not heard of Sponosad, do you think it is worth looking into?

I don't soak when I go to rockwool, I drip in gel and go straight to medium. I will start doing this, I can't see it hurting at all.

This was my understanding too. I used plain water, only 1 out of 12 showed roots after 3 weeks. I am struggling to make a connection between the change in environment and the roots starting to show in veg tent. My leading theories are 1. Health of mother a. Pests (I don't have anything...

Interesting theory, thanks for the input. The veg tent with the flood and drain table has a much stronger light (I am using 15W LED 10 cm from clones, to a 400W LED @ 50cm for veg), and more air movement, temps are ~23C in the veg tent with RH around 50%. Maybe my clone light is too weak? I do...

Thanks for replys. I have attached some photos I don't have "perfect" veg growth, I have just started playing with hydrobuddy to get a good nutrient profile, but haven't implemented anything new yet. Currently have a few purple streaks on stems, maybe a bit light on N too, but it's not too far...
