So after you add your nutes it brings it up to 1.4 or do you minus the backround EC ??
sorry is that a stupid Q?
btw :thumbs:
it includes background ec, some growers prefer to use reverse osmosis water with a starting point of 0 which is great depending on the type of root zone you want in your buckets, using r/o water means you can breed beneficial bacteria in the rootzone which helps create a healthy rhizosphere but you also need to use a clacium/magnesium supplement
with tap water it already contains calcium which is beneficial to plants and the water is sterile due to the fact it contains chlorine which normally evapourates within a 24h time period and i like to run a sterile root zone which helps keep nasty bacteria away along with plenty of dissolved oxygen normally results in a nice big root system
just different grower prefrences, tap water also works out cheaper than having to replace r/o filters every year unless your lucky enough to have acsess to low ppm drinking water
Hey seymour! I've been reading through your previous grows over the past few days, I hate to be a pain but i was just wondering, as I've never done a DWC grow before, but my next grow will be. As the grow gets older and the root gets bigger do you have to put less water in because of the weight of the root ball? also i was wondering what size tent you grow in? sorry to be a pain. Good luck with the grow! I'm sub'd!! :cough:
its normaly the opposite way round, as the root system increases the amount of nutrient uptake also increases, just imagine the roots as drinking straws and the more roots they have the more they will intake and the more they intake the bigger the plant and the bloom , ive been in situations where a full 16ltr res has nearly been emptied within 2 days
ive also mentioned before about different root types, you get roots that take on oxygen and feeder roots and i try to encourage feeder roots as much as possible by running my water level higher than what most dwc growers recommened
the general concensus is to lower the water level to below the net pot to encourage the roots to grow down into the water which is bullshit, as soon as the tap root finds food this sends a signal to the plant telling it to put more roots out so by keeping the water level higher it encorages feeder roots and with the amount of oxygen blowing into my res their is no chance of suffocation unless res temps get to high but thats more to do with enviromental control
my grow space is 1.5m x 1.5m x 2.0m and i feel restricted
hope this helps you guys out
