I see exactly the opposite.
Virtually every grow I see where people are having problems its because of growing in tiny pots, waiting to long to transplant, over watering a tiny pot in poor soil, actually most people are so freaked out about watering that they under water.
When I plant a seed into a 25 gallon fabric pot it grows like Kudzu, the roots spread out quickly, my soil is very aerated plus I super oxygenate my water so between that and the worms in my pot my roots get tons of oxygen, more than you could possibly get in a small plastic pot.
Always more than one way to do things you see.
I prefer the easy way.
I am simply explaining the way that works best for me.
If your soil is right, the soil tilth is proper, you're in fabric pots.
Then the rest is easy, plant the seed , water it, watch it grow.
Most people seem to be making this a lot harder on themselves than it needs to be.
That's growing totally organic no-till though, which personally is my recommendation for everyone.
The only hard part about it is getting your soil right, spending a good month or more just growing soil if you buy really good aged compost, if you make your own compost then need to start that about a year in advance but that's totally unnecessary when you can buy great compost aged for two years and within a month you're ready to grow.
If you have all the right ingredients in your soil, you have plenty of aeration in the form of Rice Hulls, Pumice and Precharged Biochar, get a cover crop started to get some roots into the soil, inoculate with mycorrhazae, add your worms, a handful of Gro-kashi on top, little barley hay for mulch until the cover crop comes in, add about 500 Rove Beetles for pest management.
Let all that meld for a month, grow soil.
You should be able to pour a gallon of oxygenated water quickly into a 25 gallon pot and have it disappear completely, about as fast as pouring through a screen door.
I water frequently, and everytime I water it's with super oxygenated water from 02 emitters so my roots get a steady supply of oxygen plus the soil holds oxygen.
Then plant a germinated seed into that soil, I water with a spray bottle first few days, after that just water the pot normally, keep the soil moist NEVER let it dry out and its virtually fool proof.
No worries about pH because your soil takes care of it.
No worries about over or under feeding because your soil and microbes take care of it with just minor inputs from you.
No worries about over watering because the soil is proper with correct tilth and you're in a fabric pot with a minimum of 15 gallons of soil with worms aerating it and cover crop roots helping plus the cover crop helps keep the soil at proper moisture level.
You basically can't overwater short of tossing it into a swimming pool.
In this method you CAN however under water, you pretty much treat this kind of soil grow like you do Coco.
But the soil is so porous, and the cover crop helps balance out everything so really it's damn near fool proof which is why I always preach this method to everyone n00b or not.
The only hard part is before you even start growing cannabis.
By the time you plant the seed all you do is water and watch it grow.
You also get the added benefit of 100% organic and the best tasting bud you'll ever smoke.
