EC levels

[bigawse]

Hi all, first time on here so give me a break if sounds bit stupid

 

Heres the story, I've grown a bunch outdoors but have started trying the girls indoors.

 

I tried first time and ran coco peat under a 600w in a tent on a run to waste. I never really bothered with PH and ec just followed the instructions on the back of the bottles of A&B. Unfortunatly I have to go away for 3-5 days at a time and sometimes a full 7 days. This didnt work caus i think I overwaterd it using a pump and a timer. Any way I got spider mite and couldnt bring em back, was too far gone.

 

So I've decided to make it easier and am running rocks with clones in rockwool on a recirculating system. I have purchased an automatic doser for PH an EC. Runs with peristaltic pumps is pretty cool, so far keeps EC and PH at exact levels and all I have to do is calibrate the sensors once a fortnite.

So far is going good.

 

Was just curious as to what EC levels I should use. My plain tap water EC is like 1.5 so I have started running it at .5 higher than that so 2.0 , was just curious when i shoudl increase this and by how much. Seems to be liking it but I have never run a system like this with pumps and shit.

 

Am keen for any feedback or help or anyone else used these autodosers?

 

Cheers

the general reccomended full dose is to go about 1.4-1.6 above your water levels however that starts to get risky with water as hard as yours so you really need to ballance it out as you have no controll over what those messured elements are in your tap water

 

What I would sugest is reasearching the nutrient manufacturers and getting information on their catchment , it's all readly available information online and can help you decide on a company that already accomidate to a similar water supply

 

Having deal with water nearly that bad myself I feel for you

 

one of the best solutions for you imo past finding a suitable nutrient is an RO filter to bring your ec back down to 0

Thanks for the help

 

What sort of cost are you looking at for an RO filter?

roughly cost ya anywhere from 350-500 depending on where you purchase from
