What is the role of circulating water in a hydroponic system?

So in many of the hydroponic systems like the vertical and horizontal ones water is circulated with a motor

This is obvious since otherwise water won't reach the plants

But is there some other reason as well to keep the liquid in circulation? There are also other arrangements to grow in a static liquid reservoir ( I am also currently working with one using a strainer and a bowl below ).

How does it differ growing a plant among these methods?

SERIOUS: This subreddit needs to understand what a "dad joke" really means.

I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.

Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.

Meets 2/3, 12 Week Training Update

I’ve just ended my second 6-week training cycle with my first 100- and 400-meter races of the season. I willΒ give an update on how I did in those races. I will offer a brief synopsis of the past 6 weeks of training and discuss the next training cycle.

Meet 2 (November 13, 2021)

60m: 8.69 (previous time 8.82) Running my first 60 in October gave me a goal to shoot for. I was able to improve. I was around 3 weeks deep into my strength regimen and I felt as if I could accelerate for longer.

800m: 2:40.6 (previous 2:37.2) I didn't do as well the second time around. There was much less rest between events, which may have contributed to the slower time. The 800 is now my worst event and I will be exploring strategies to improve next fall.

Meet 3 (December 11, 2021)

100m: 13.31 (previous time 14.19 w/headwind in August) I’m pretty satisfied with this time. I lost a lot of speed last summer as explained in previous posts. My goal was to run in the 13.0-13.2 range as a jumping point to sub-13. I think this time will give me enough of a boost to do so in the next 1-2 months.

400m: 63 or 64 (previous time 63.03 in July) I refused to run the first 200m fast enough to PR. The race felt smooth and wasn't too difficult. In my best 400 (60.7) I ran the first 200 in 28 seconds. Today, I did so in around 30 seconds. I will be exploring pre-meet and specific endurance work to address this issue.

Testing Week 2

Last Tuesday, I carried out some sprint tests. Here are the results:

30m: 5.05 (probably faster than last time) I’m sneaking up on the time range of my peak from January-March of this year. Force velocity profiling with the MySprint app indicates a more velocity-oriented profile characterized by reduced peak force/power and an improved ability to attenuate the loss of horizontal force. This aligns well with today’s race, where I was only able to separate from my competitors past 50m.

20m fly with 10m splits: 2.49, 1.25/1.24 (previous time 2.59) I’m pleased with this time. It feels great to finally be restoring my speed after months of slow times. The second 60-meter race, as well as the weight training, has given me a substantial boost. I’m hoping to split under 1.20 in the next 1-2 months.

150m: 19.93h (PB, previous best 20.3 in August) I was also quite happy about this time. Other than some long hill work, I haven't trained any speed endurance. It gave me a lot of confidence (or not) going into today’s

The pre-existence and consent in child-parent reltionships

This may ruffle some feathers but it's been bothering me for a while. TW: child abuse.

I was taught that I chose to live with my horrendously abusive mother and spineless enabling father who fucked me up so badly that I'll likely be recovering for years to come, despite being in my mid-30s with a over decade of hard work and little to no contact with them.

My brother recognized some of the abuse as a teenager and went to church leaders about it. They told him that it was a trial from god because our parents were temple-worthy (LOL) and attended regularly (despite Jesus teaching that it would be better for them to be drowned via millstone). We had been "blessed" to be born into a home where the gospel was taught and would one day "owe" our parents for providing such basics as a roof over my head, food, clothes to wear, access to healthcare, and so many other "privileges" that exacted our undying gratitude. When they were old, we would be obligated to return the favor...honor thy father and mother.

I'm calling putrid ruminant-digested anaerobically fetid bullshit.

Children cannot consent.

The child-parent relationship is probably the only potentially healthy relationship most people will have that does not originate or operate in mutual consent. My parents chose to have me and therefore chose the responsibility of providing the things listed above. My consent was nowhere to be seen because it did not exist.

I have a theory that an operative aspect of this series of lies from a church perspective is getting people comfortable with having more children. "They'll take care of me in my old age" is something I hear pretty often. Oh, will they? The reality is that they don't owe you anything and never will. Even the most loving and wonderful parents don't have any right to expect anything from their children in return for their efforts. Hopefully children decide to love and support their parents but that support is freely given and cannot ethically be demanded by parents, a religious organization, or anyone else. The lack of consent on the part of the child negates the claim that they bear any responsibility in the child-parent relationship.

The thing I found interesting was that upon closer inspection, the church teaches that this relationship isn't founded in consent, after all. They teach that it's pre-determined by god and then accepted by both parties in a disparate state of consciousness created by the veil during earth life. If we choose no

Has anyone tried adding store-bought kefir to a batch of homemade?

I think my grains have become a little too yeasty, so I was thinking about adding some Lifeway kefir to the next batch I make just to see if it thickens it a little and gets helps achieve a better bacteria balance. Anyone ever try something like this?

EDIT: I just did it, so I'll update tomorrow on how it goes.

EDIT2: Okay, I think it is now worse, the curds and whey separated completely and in less than 24 hours. It's also a possibility that my ratio is off though. So idk how useful any of this info is, but there you have it.

Just because it's a joke, doesn't mean it's a dad joke

Alot of great jokes get posted here! However just because you have a joke, doesn't mean it's a dad joke.

THIS IS NOT ABOUT NSFW, THIS IS ABOUT LONG JOKES, BLONDE JOKES, SEXUAL JOKES, KNOCK KNOCK JOKES, POLITICAL JOKES, ETC BEING POSTED IN A DAD JOKE SUB

Try telling these sexual jokes that get posted here, to your kid and see how your spouse likes it.. if that goes well, Try telling one of your friends kid about your sex life being like Coca cola, first it was normal, than light and now zero , and see if the parents are OK with you telling their kid the "dad joke"

I'm not even referencing the NSFW, I'm saying Dad jokes are corny, and sometimes painful, not sexual

So check out r/jokes for all types of jokes

r/unclejokes for dirty jokes

r/3amjokes for real weird and alot of OC

r/cleandadjokes If your really sick of seeing not dad jokes in r/dadjokes

Punchline !

Edit: this is not a post about NSFW , This is about jokes, knock knock jokes, blonde jokes, political jokes etc being posted in a dad joke sub
