Repotting

This is my first time at indoor plants.
what schedule should a grower be on when it comes to flower pot size? That is; from seedlings to mature plants, what size pots do you use, and when do you increase the pot size? Do you use a clay pot, plastic, or other?
thanks
 
I start with a 1 gallon fabric pot,and pot- up when they are ready, usually to a5 or7 gallon, fabric pot is your best choice
 
Every time you transplant you open yourself to plant damage and always have a modicum of transplant shock that will temporarily slow down growth.
Remove the cotyledons on your plant.
Fill a 7-gallon pot of any of the materials you mentioned with whatever grow medium you decide to use. You can literally walk in your local garden supply store and pick a pot you think looks nice, whatever the material. The more porous the material, the more often you will water. Bags have handles. While porous fabric pots breathe, porous clay pots wick moisture from soil. Tapered pots are easier to knock over.
What you have been using for soil looks fine. Fill it to 2" to the top of the pot. Water the pot so the water pours out the bottom. Wait 12 hours.
Remove the plant, soil, and root ball from the peat pot it is in. Cutting down the sides of the pot might be the easiest.
Dig a hole in your pot deep enough so the cotyledons would have been level with the soil. Put your plant in and fill the hole. Water the pot.
Grow.

I assume then that you do your first transplant putting the seedling into a 1 gallon fabric pot. I have a second group of seedlings that have not been damaged by overwatering and light burn. I read that a good rule of thumb is to transplant the seedling when its follage reaches the diameter of it as container. Do you agree? Or would you transplant this one now before it reaches the pot diameter? And when you say you would start in a one gallon fabric pot, do you mean that you would germinate the seed in a one gallon or do you mean that you would transplant it first into a one gallon?

So you are saying to bury the plant up to its cotyledons in a 7 gallon pot, so it can sprout new roots along its stem? Sounds good. I was afraid these were toast.
I have a question on watering. I read on this site I believe about watering and pot size, and it said that if the pot is bigger than the plant that the roots can drown because the plant doesn’t take up the water fast enough. So the trick is to provide the correct amount of water. What I gathered is that it is best to water close in around the plant, and water just enough and often. Do you have any additional advice?
 
The picture you just posted is not the picture you posted in your previous post. I would put this one down 1" below the coty's in a 7-gallon bag. I say 7-gallon bag because your other plant is photo and I assume this one is as well. That means you have the opportunity to grow those plants into 7-gallon plants: Big 'uns. I say bags because bags have handles, are easy to manipulate, self prune roots, and are stable. Yeah, I'm clumsy.
Everything you said about watering is golden in my book. Keep the watering to a little past the drip line (edge of the canopy). Like people, plants do not drown from too much water. People die from not getting enough clean oxygen to their brains. Plants die from not getting enough clean oxygen to their roots.
I no longer transplant for the reasons I gave. My first grows went seed on towel, Solo cup, one gallon, five gallon. I killed a lot of plants by breaking the toweled sprout, dropping Solo cups, and stunted plants after transplant. I now put my seeds in 5-gallon coco/perlite bags and let them do their thing.

Yes it is a different plant. I made mention of it but didn’t make it clear. I said “I have another set of seedlings that have not been damaged by overwatering or light burn.” I meant to then say “I am attaching a picture of one of those.” That would have made it clear that I have two groups of seedlings that I need help with.
 
I need to make sure I understand your advice.
Are you saying to bury both plants up to their cotyledons (small non serrated leaves)?
 
What do you use for a saucer under the 7 gallon pot? I was going to order fabric pots from Amazon and the dimensions on the 7 gallon pot is 15” on diameter.
 
Another question; watering a small plant in a big pot;
How do you know that the amount of water is correct?
I don’t have my 7 gallon fabric pots yet but I put one of my problem plants in a 10” diameter clay pot and watered it just below the leaves (or close to that). That leaves a lot of soil outside of the plant unwatered. Also the soil around the stem drinks a lot of water, or it could, and I don’t want to overwater. How do you know when you’ve watered it enough? How do you know that it’s time to water again?
Edit:
I failed to saturate the soil in the larger pot and wait 12 hours. I missed that the first time I read your instructions. (It may work out ok. I think I got too much water around the stem. The soil outside of this will soak more of this up since I didn’t saturate it.)

My reply about removing and burying up to the cotyledons was in reference to your 'Sick Plant' thread as you had not posted the picture in post #6 in this thread.
For the plant in this thread, bury it up to an inch below the cotyledons (I did not say remove them. They are healthy on this plant.)
For your other plants, I don't know what they look like so won't say anything.
A thing about transplanting deeper is the part of the trunk of the plant that gets covered by soil will grow roots it otherwise would not.
When to water comes with a little experience. My method is by weight. I know how dry my plants are by lifting them, one of the handle bonuses. For no experience, I would start with a simple moisture meter. Get the biggest and most expensive you want, but a simple two prong thing you stick in the dirt is just fine.
How much to water also comes with experience. I know one gallon does my bags perfect when they get going. In early stages, man, I'm sorry, but it's experience. It seems like a continuous, oxygenated drip would be best for seedlings, but don't quote me on that.
I grow in 5-gallon because of the size of my tent. 4, 5-gallon plants max my space. If I had lots of space I would be topping feminized in at least 7-gallon. You can find saucers and stands of any size online.
Small plant-big pot. One good watering of the whole pot, then follow the drip-line.
 
Potting up tomorrow when the 3 gallon pots are here

Is 3 gallon the largest size you will use? I’m curious for several reasons. If 3 is not the largest, why do you use an intermediate size? If it is the largest, what height plant do you expect (and yield)? I think 3 gallon is about right for me and my space limitations (10” diameter). (I’ll return the 7’s.)
 
Brwnthmb It's time to head to the website and do some research. I see you doing things and planning on doing things and missing or forgetting things.
Take a look at the sample grows and lifecycle of cannabis. Figure out what you can do with what you have, where you want to go, and what you need. I know that's what you are doing but you are not giving the whole picture and we cannot give well informed advice.
 
I went with 3 gallon pots because 5 gallon pots are too big for the tent, I'm trying to buy some time while the 3 plants in the flower space finish up,then I'll pot up to the 7 gallon pots,veg for a few weeks and flip the lights to flower
