Repotting, run off or not?

Hey everyone, iv just repotted some seedling into 6.5 litre pots using ecothrive lite coco, do I need to feed them to run off or just feed untill damp through?

I always make a quick getaway after repotting. The ladies hate it.  

The purpose of watering until run off is to stop salts building up. If you've just repotted, there's probably no need as there is presently no build up in the fresh medium.

Thankyou bud, thats what I thought, I had previously been watering to run off when repotting but noticed that it was taking upto a week to get light again, hopefully I can get my root going a bit quicker now

Run off also helps to tell you the pot has been fully saturated.  It would be best to water the pot to run off a day prior to transplant, using an empty pot to hold space for your plant. That's a big pot for a seedling though.

That's why people pot up in stages, well I assume coco is the same. I've never got around to trying it :blushing:

I use compost but I’m sure it’s the same principle. But I’m led to believe if you water too much it just sits waiting to be supped up hence yer heavy pots. I just lightly water in/dampen media before popping plant in. This way I think it encourages roots to search out water. Because the pot isn’t rooted out that water/dampness should last a good 3 days or so.

Perhaps I’ll be put right :yep:

I ended up doing a side by side with 2 of the most identical clones, watering one untill run off and one just moistend.

 

The first to have roots poking through the bottom of the pot was the one that was just moist.

Probably because it's searching for water as parts of the medium weren't wet. Fully saturating a pot will mean all the medium is evenly wet so the roots will try to grow into all of it. I bet a pot with just water in the tray will have roots poking out even faster, don't mean it's a good thing

Makes sense Il have a look at the roots in the next few days and see if the one I gave runoff has a more dense root system

If I did that though personally id probably just water a litre or so.Just enough to keep them happy. So i don't push all the air out of the medium...

 

Slowly increasing the amount.

 

Ive done 1.5 litre fully rooted and sexed in 1.5l to 11 litre watering as above.
