It shouldnt piss anyone off that people choose to pickup a hobby in different ways. Some have more time than others and some have more of an emotional investment as well. You should not judge people who ask questions first off as 99% of the time no question is a bad one. No one should be pissed off and have to say so, if you do not like the thread do not respond to it, just basic respect.
On the other side yes it can be slightly annoying to see a forums go nub-cakes with multiple threads all asking very basic questions. However this is the watering thread and a single thread again is hardly something to get pissed about no matter how busy with newcomers it is. Bubbles was correct in telling them that they should maybe do some more research but on the other hand they very well could of and that research was so conflicting that they felt the need to ask anyways.
The answer on how much to water:
Considering every growing is unique in their setup the amount of water you give your plant will depend on multiple variables.
some of which are:
1. Growing Medium (mixed or not, retention qualities,and the nutes that is may/may not contain)
2. Plant size, age, absorption rate of water
3. Whether you are plain watering or nutes watering
4. Pot size
General Watering for soil :
Just planted: about 100-200ML of water, completely hydrate the entire medium, this is if you germinated seedlings
Seedling Sprouting: Finger check top 1/2 of soil( do not disturb the seed!), if dry water 50ml right above where u planted.(this is assuming you planted the seed 1/4 inch-1/2 inch in dirt)
Sprout: finger check top 1" of soil if dry give 100ml of water, a good rule of thumb for plants is for every 1 inch it grows up it roots down 2 inches. So if your guy is growing .5 inches per day or 1/4 inch then check that much deeper into the soil with your finger, so you know if the roots are getting water at their level. Once the roots reach bottom increase to 200ml of water whenever dry. This is usually every 2-3 days depending on your humidity and light and other variables. A baby plant can be over watered easily however once it gets big its very hard to over water it. A good rule of thumb is to water for 1-5% run off for baby plants every 2-3 waterings and for 10-15% for juvenile-adult plants. It depends on mainly how advanced the rooot system is, if its advanced you need to over water more often maybe everytime.
You personally will have to experiment and take it from here. Read up as we all have spent many many hours including myself reading up and no new person is any different.
General Watering for Hydro :
It depends greatly on the amount of watering each time, the size of the plants, spraying or pour watering spigots, is it a hydro system or are you doing hydro plants individually, growing medium mix and its rentention qualities. One with hydro setup but not auto watering will want to treat it like a more frequent soil, and overwatering should be done everytime. the excess water should be recycled into the water system always or you are going to be dumping drained nutes as when you do feed water your plants the medium holds the nutes in but you will be watering often so some waterings are just normal water, youll flush those nutes right out if they arent absorbed yet! Recycle your water!
With automatic watering systems you will have to check often and make the adjustments. Not only are your plants going to demand more and more every day but you are going to have to experiment to get them at the right % levels from the start. hook up only a couple of plants and see how they do day by day, if its good plug n play more of your plants until its full. They are going to require an increase in waterings every week almost and possibly even more so when older. You need to make sure you have all your testing equipment right as you are growing all your plants on the same system, on screw up can quickly affect all as they LIVE off of your waterings.
Some say hydro is easier but honestly a good mix of soil is by far the easiest grow and the most money saving. Even if you drain the nutes from soil you replenish them with feed waterings. The mixes have greater retention qualities than hydro but less aeration quality ( this is where your mix really defines your grow ) but saves you $$$$ on nutes since you do not have to feed from the start!
I am sure a true guru can come post over me and have alot more advice but I have just been reading like crazy and well this thread is for watering and doesnt have an explanation yet. so here is a decent one
