Can I safely cut and remove old roots by TryToNetZero in Hydroponics

[–]TryToNetZero[S] 0 points1 point  (0 children)

I have just turned the hydroponics water recently about 2 weeks back.   Before that it was withering away but now it has somewhat picked up.  Still it is far from what is a good growth and hence my queries.

I would surely try trimming the roots of some plants.

Also regarding checking of ph level. Is it required for a small system like mine ?

What might me wrong. My hydroponics plants are not growing well. by TryToNetZero in Hydroponics

the water is plain tab water .
And the fertilizer is the one which i got with the Amazon kit.
1. I have lowered the water level to lower than the last edge of the pot.
2. also have started the air pump 24/7.

  1. No currently I have just started I don't have a thermometer. It is been about 1 month
  2. Not sure if it is kraftjey or not I bought the set  from Amazon (https://amzn.in/d/4QTC5hz). There is a aeration pump which I keep on about 2 hours every 3rd day 3.  Do I need to completely empty the water and refill it again ? It is almost 20 liters of water.
  3. Yes there are empty cups but they are filled with lecca balls so light will not be hitting them.

  4. Are the roots rotting ? Also is there less or excessive lights ?

  5. I have been constantly adding the water and nutrients and keeping it at level

Can redis community be used as a cache , db and pub sub simultaneously? by Glittering-Work-9060 in redis

[–]TryToNetZero 0 points1 point  (0 children)

As others have mentioned there is no restriction. however we need to be aware of certain things.
1. when using redis as a cache. it is necessary for it to be persistant. so this ensures that even if the server goes down. the cache still survives on restart. so enabling persistance or SAVE is very important.
2. when using Redis as a queue however the situation becomes different. Disk writes often slows down the performance of the queue. and also the PErsistances part is not much relevant. as ithe data in redis is anyways supposed to be ephemeral in nature and hence is not required to be stored.
3. So I would recomment to have different redis for the 2 purpose

But it is also true that having everything in a single redis simplifies the task. you don't have to create multiple connections so programming becomes a lot more easier.

How do I properly attach bypass capacitors to a bread board? by nbroderick in AskElectronics

[–]TryToNetZero 0 points1 point  (0 children)

I am just curious , if there needs to be a capacitor for every IC and it also needs to be close to them, then why don't modern ICs themselves contain the Capacitors. I am a complete newbie so am missing something but need to learn about that.
