Q & A
What was the first mistake mentioned in the script regarding nutrient concentration in a hydroponic setup?
-The first mistake was not considering nutrient concentration and starting with a maximum amount of 1500 parts per million (PPM), which could lead to over-concentration to around 3000 PPM at the bottom, potentially ruining the plants.
What is the recommended approach to avoid over-nutrient issues in a hydroponic system?
-The recommended approach is to start with half the target PPM. For example, if the target is 1500 PPM, start with 750 PPM to account for the concentration increase as water evaporates.
What is root rot and how can it be avoided in a hydroponic setup?
-Root rot is a condition that occurs when there is too much water and not enough air in the root environment. It can be avoided by ensuring proper air-to-water ratio and using hydrogen peroxide as an oxygenator to increase oxygen levels and clean the setup.
Why is hydrogen peroxide recommended for hydroponic systems, and what is the correct ratio to use?
-Hydrogen peroxide is recommended because it acts as a natural oxygenator, increasing oxygen levels around the roots and helping to clean the setup. The correct ratio is 10 milliliters per gallon of 3% hydrogen peroxide.
What is the importance of calculating the container size correctly in a hydroponic setup?
-Correctly calculating the container size is crucial for understanding the plant's growth cycle and ensuring that the nutrients concentrate at the right rate. An improper container size can lead to issues such as nutrient imbalance or inadequate water supply.
How does the growth cycle of the plant correlate with the size of the container in a hydroponic setup?
-The growth cycle of the plant determines the size of the root system and the amount of time the plant will grow. Larger plants with more complex root systems, like tomatoes, require larger vessels for adequate water and nutrient supply and slower evaporation rates.
What is the common mistake made by beginners regarding grow lights in a hydroponic setup?
-A common mistake is keeping the grow lights too far from the plants. Beginners often err on the side of caution, placing lights too far away, which can result in insufficient lighting and slow plant growth.
What is the recommended distance between grow lights and plants for optimal growth?
-The recommended distance is 12 to 18 inches away from the plants to ensure optimal photon density and light exposure, which is crucial for plant growth.
What are some strategies to prevent algae growth in a hydroponic setup?
-Strategies include blocking light to prevent algae growth, growing fast-growing plants like leafy greens and herbs that don't give algae a chance to grow, and using opaque containers to block sunlight.
Why are leafy greens and herbs recommended for hydroponic setups that use clear jars?
-Leafy greens and herbs are recommended because they grow quickly, which helps to outpace algae growth and doesn't give algae an opportunity to establish itself in the jar.
How can the issues mentioned in the script be addressed to ensure a successful hydroponic setup?
-By carefully considering nutrient concentration, preventing root rot through proper aeration, calculating the correct container size, ensuring adequate lighting, and preventing algae growth, a successful hydroponic setup can be achieved.
Outlines
🌱 Avoiding Nutrient Overload in Cracky Setups
The speaker emphasizes the importance of not overdoing nutrient concentration in hydroponic setups, particularly in 'cracky' systems. Initially, they made the mistake of using too high a concentration, leading to plant damage. The correct approach is to start with half the desired target PPM, allowing for natural concentration as water evaporates. This method prevents nutrient overload, which can be detrimental to plant health.
🌿 Understanding Root Rot and Oxygenation
The paragraph discusses the issue of root rot, which is often caused by an excess of water over air in the growing medium. To combat this, the speaker recommends increasing air circulation and using hydrogen peroxide (H2O2) as a natural oxygenator. By adding a specific ratio of 10 milliliters per gallon of 3% hydrogen peroxide to the nutrient solution, it not only provides oxygen to the roots but also helps clean the setup, thus preventing root rot and promoting healthier plant growth.
📏 Calculating the Correct Container Size for Cracky Setups
This section focuses on the importance of choosing the right container size for a cracky setup based on the plant's growth cycle and root system complexity. The speaker explains that understanding the plant's needs and the evaporation rate is crucial for nutrient concentration. A mismatch in container size can lead to issues, so it's essential to align the plant's growth with the appropriate container and nutrient concentration rate for a successful setup.
💡 Optimal Distance for Grow Lights in Plant Growth
The speaker points out a common mistake among beginners regarding the positioning of grow lights. They suggest that lights should be kept as close as 12 to 18 inches from the plant to ensure optimal photon density, which is essential for plant growth. This advice, although not directly related to the cracky method, is a fundamental aspect of successful plant cultivation that can significantly impact growth rates.
🌿 Preventing Algae Growth in Cracky Setups
The final paragraph addresses the issue of algae in cracky setups, especially when the setup is transparent and exposed to light. The speaker suggests growing fast-growing plants like leafy greens and herbs to outpace algae development. For larger plants, using opaque containers is recommended. Additionally, they reiterate the importance of the strategies mentioned in a previous video to avoid algae, ensuring a clean and effective hydroponic system.
🗣️ Engaging with the Audience and Closing Remarks
In the closing paragraph, the speaker invites viewers to share their experiences and results in the comments section and signals the end of the video with a friendly 'bye-bye.' This approach encourages viewer interaction and creates a sense of community among those who are also exploring hydroponic gardening.

Transcripts
so the first mistake is not considering
nutrient concentration when I first
started out I would just load in the
maximum amount of nutrients like 1500
parts per million and then by the time
it concentrated down to the bottom I'd
be looking at like 3 000 and my plant
would be ruined at that point so when
you first load in your nutrients into
the cracky setup the idea is that as as
the water evaporates the nutrients are
going to concentrate more and more so
you really don't want to load in that
many from the start otherwise you're
going to end up with an insane amount of
nutrients by the end my general rule
here is I load half if I'm looking for a
Target PPM of 1500 then I'll load in 750
to start
that's my way of avoiding over nutrients
by the time you reach that concentrated
nutrient in the bottom number two
root rot
understanding what causes root rot is a
great way to avoid root rot and every
time I've run into it in my setups it's
been because I've had like way more
water than air so how do we get air into
a cracky setup you might ask the general
principle and design of the cracking
method is to allow more air into it as
the plants getting bigger and bigger but
let's say there were some
miscalculations along the way or I don't
know something went wrong from the start
and you need to get more air into the
jar before the evaporation happens a
great way to do that and something I
would recommend really for all your
hydro Gardens is to add some H2O2 or
hydrogen peroxide it is a natural
oxygenator oxygenizer oxygen oxidizer so
simply by adding 10 milliliters per
gallon of three percent hydrogen
peroxide to your nutrient water you're
gonna be adding quite a bit of
concentrated oxygen too and you start to
even see little bubbles on your roots as
it works away and knowing that it's in
there not just adding oxygen to your
roots but cleaning your whole setup is
just a fantastic feeling so you really
can't go wrong with adding hydrogen
peroxide don't forget that ratio and it
might just save your setup the third
mistake that people make when putting
together their cracky setups that is not
calculating the container size right to
do this properly and to calculate the
container size right you really have to
understand how the cracky setup works
and you have to understand the plants
you're growing a little bit you know if
I was trying to grow you know a tomato
plant then I would need a much much
larger vessel because that's going to
have a much more intricate and larger
root system and it's going to grow over
a larger period of time so you're going
to need a lot more water and you're
going to need to evaporate a lot slower
so understanding the growth cycle of
your plant and correlation with the
sized container you're planning on using
and then also in correlation with making
sure your nutrients are concentrating at
the right rate it's all really key to
making a good cracky setup work if one
of those things are out of sync then you
could end up with real issues so number
four
so I think it's pretty obvious when your
grow lights are too close but that's not
usually what I see when it comes to
beginners usually it's trepidation not
over zealousy that leads to growth
issues so I mean grow lights are made to
be 12 to 18 inches away from your plant
if you look at these ppfd images you can
even see that the power output or the
photon density between 12 inches and 18
inches is almost halved so making sure
that your lights are really close to
your plant are it's going to be it's
going to make a really huge difference
when it comes to your growth I know
that's not directly related to the
cracking method but that's something
I've seen a lot and that's an issue that
that I had when I first started off and
I didn't understand why my plants
weren't growing very fast and then I
realized that I wasn't giving them the
proper lighting you know if you could
try to always keep your light about 12
inches from the top of your plant and as
your plant grows you can move your light
up that's kind of a really good general
rule to make sure that everything's
going to grow properly
so number five the final issue or
mistake that people make or run into
with cracky setups is algae thing is if
you're serious about doing a cracky
setup or a cracky Garden likely you're
gonna have five gallon jugs you're going
to have covered jars you're going to
have the UV jars and algae is not really
going to be an issue for you because
you're going to have all your sunlight
blocked but if you want your cracky
setup to be in your kitchen or you want
it to be a Showcase in your house and
you want to be able to see all the roots
then here are a couple things that you
can do to to try to avoid algae I
mentioned a few things in this video
definitely check that out as well these
are going to be totally different things
it might seem a little bit like
no-brainers but hopefully they can help
you out okay so obviously blocking light
is the best way to keep algae out but if
we're going to have a clear jar what's
the best way to avoid getting algae well
I actually think the best way to avoid
getting algae if you're growing in a
clear jar is to just grow something that
grows fast leafy greens and herbs are
fantastic for the cracking method
because they grow so fast that they
don't even really give algae a an
opportunity and then if you're going to
grow something bigger likely you're
going to use something like a five
gallon bucket or a big tub anyway which
isn't going to allow any sunlight in so
if you do the two things that I
recommended and the last video as well
as just growing you know leafy greens or
herbs in your mason jars then you really
shouldn't run into algae and if you take
the other four things to Heart then
hopefully you don't run into any other
issues at all I look forward to hearing
about how everything goes for you down
in the comments and I'll see you guys in
the next video
bye-bye
