###########Welcome to week three of my DWC Buckets guide #####################
This week I will try to explain TDS and PH meters and how to keep them accurate .
But first a quick update on the Plant.
The Blue cheese is going as well as can be expected and has developed a very long tap root that has grown well down
into the bucket full of aerated nutrient solution. The strength of this mix is still quite low but she will be getting a full resevoir
change and new nutes with Professor's A&B nutrient's will be used. π
Now back to Ph and TDS meters.
When starting out with hydronics or growing in general it can be daunting for newbies when looking at equipment needed
They see more experienced growers using this brand or that light etc etc but this is because they have had the experience
to know what works for them.
For new growers just starting out I would reccomend getting one of the more budget friendy TDS and Ph meters
available and learn how to use these well before buying the more top ended brands such as bluelab etc.
Vivosun makes such budget models as well as many other poular brands you can find on Amazon or ebay.
When purchasing the meters it's important to also get some Ph 7 and 4 buffering solution as you will need to
calibrate your Ph meters atleast once a month whilst they are in use.
It's as simple as placing the ph meter's probe into some buffer 7 solution wait until the reading settles on 7 press calibrate then repeat with the buffer 4 solution.
Now a quick guide to what your plant needs during each stage of growth. This is a General guide only.
Week1 -3 Early vegetative stage 150-300 ppm
Weeks 4-8 Late vegetative 600- 800 ppm
Weeks 9-10 Transition (stretch) 800-1200 ppm
Weeks 11-13 Early flowering 1000-1200 ppm
Weeks 14-16 Mid flowering 1000-1300 ppm
Weeks 15-17 Late flowering 1000-1300 ppm
Weeks 18-20 Ripening 1000-1300 ppm
Week 21 Flush 0-400 ppm
Remember that as a rule of thumb guide always halve the nutrient companie's reccomended dosage as their
growing under ideal conditions and those strengths will be too hot for your plants.
Well that concludes this weeks guide Next week's topic is nutrient mixing See you then π
Nice info! This will help a lot of people starting out. That exhaust out the window like that on the ac is false advertising I think lol. There is a water hose that drains condensation from the cooling coil and it can't go up like that. It has to go down or it will leak.
Looking good man. So does silica in general help keep that PH where you want it, or just the brand your using. Also silica helps plants handle higher temperatures if I'm correct?
@jollychap, I think it acts as a buffer in all the brands of silica and yes it makes the plants cell walls stronger
so they can handle more stress like heat etc
I'm very interested to learn if you can manage your humidity issues with your new dehumidifier. I personally gave up on this. It will increase the temperature to unacceptable levels. Of course the humidity will decrease with the higher temperatures, but for me it is not worth it. Also the unit I have draws more power than all my lamps combined. Probably it is better to do an indoor grow in winter when it is so much easier to control the environment.
