Flushing plant question

[mehl420]

How do you flush out a plant?

[experimentalist]

Flushing means to clean the soil. Basically you want to use three gallons of fresh clean
water for every one gallon of soil. You run the water through the soil until it all drains out
the bottom nice and clear. You NEED a pot that will drain to achieve this.

You typically need to flush the soil if you are:

a) unsure of its existing nutrient content.
b) you have added too much fertilizer and your plant has nute burn.

You will want to flush your soil and re-add nutrients to the plant so you know exactly
what your plant has coming to it.

Remember to use water which is at room temperature, you don't want your plant
taking any additional stress with the sudden temperature change.

Also be sure that the water is at the Ph you desire, and consider changing the
Ph to achieve a 6.5-6.8 for optimum nutrient intake.

I hope that helps!

thanks...ive heard this is also suppose to be done a week or so before harvesting so it doesnt have a fertilzer taste, is this true?

Lime is alkaline and RAISES pH.

I have never found ´flushing´ makes any difference to the taste. But there is an argument already going on about that in another thread.

At least a week! Some people will flush for the last three weeks of flowering. I'd imagine
it has to do more with the size of your plant. I do two weeks personally.

There was a great thread about adding Blackstrap molasses to your water during the flushing
period, it activates a lot of the microorganisms which assist the plant in its final stages. I
recommend you search for it and read it, it was great.

Hope that helps!
