A question from a fellow grower:
Question about seeds. I can purchase 4 x 2.25 inch seed pots or 6 inch x ?
Which should I get? I was worried if I only got the 4 x 2.25 I might have to transplant sooner and that was my next question. How many times will I need to transplant during one grow cycle? What size pots should I get in advance? I just saw a video of mature cannabis plants being grown in those giant rubber garbage cans but I don’t have that kind of space.
3 gallon pots are perfect for auto plants
It does depend on how big you want the plant to get and what type of grow and or training you want to do and how much space you have to grow in.
Inside growing. I start with 3" pot, then transplant to 1gallon or 6-7"?, then when I induce flowering; I transplant to a 3 gallon or 13liter pot.
No need to place a small plant in a large pot. better to transplant. This will gain you better root support throughout your grow. Starting off in too big a container leads to the roots growing downward, and you end up wasting, by not using, 1/2 your soil.
I it in 5 gallon or 18lt all the way in 1 pot
