Why should I re-pot my plant

[The HSIC]

This is a question we hear all the time.
When your growing a plant from seed, and finishing it at about 3 feet tall, you should expect to transplant at least twice, probaly three times during the grow.

Why is this?

Losing light to the soil surface is undesirable, so having smaller pots and a continuous canopy is much more efficient.

Letting the plant focus too much energy underground is inefficient also, the roots should grow out to the sides of the pot and just chill there for a while while the leafy part grows. This is why you water from the sides, and not from the center.

Unused soil zones within the pot can be wet and stagnant where the roots can't access the moisture in them. That's not good.

When you are, as many many growers are, growing in a peat based medium, you want to minimize the amount of time that new roots are in old soil. When a product such as promix is packaged, it is buffered with lime to bring the pH up from the natural pH of peat (4.5-5.5 or so) into a more suitable range for common plants. That lime buffer is good for only so long after water has been added and it starts to react with the acids in the peat. After a couple months or so, many growers will note a drastic drop in pH and sudden lockout symptoms. One way to avoid this is to constantly be potting up and refreshing the soil AROUND the root ball so that fresh roots can access fresh soil.

Is it ok to repot in the middle of the flower stage?I know every time I repoted before,my plants took off and never even hiccuped in the slightest.I am a bit over 4 weeks now and buds are getting big.I have room for a 5 gallon bucket but I will have to get fresh soil as I took all my old away.

it is as the roots continue to grow in flower, but if you are already in 5gal buckets i don't see much of an reason to replant those anymore (if they are no 10ft sativas you grow there)

Naw, I'm in a 2 gallon pot.I could do a five gallon bucket But I think I will just stay with what I have.Bigger yield would be nice tho; )

Pineboy, if your not very comfortable re-potting, I would recommend that you try not to re-pot during flowering, you could piss 'em off.

Also, when you do re-pot, never change your recipe, if you gotta buy more, get the same brand as what you started with, or you could piss 'em off.
Peace
