yeah mate i did bout two weeks ago. cutting a long story short i had a number of badly nute burned plants, one wasnt goin to survive so i decided fuck it im goin to try sumthin i'd seen in here done . basically i took my plant and put it in the bath and as i had been tryin to flush it anyway the soil was soaking wet, i got a cloth to cover the plug hole thereby filtering a little and i just stuck my hand down the side of the pot and scooped the whole bloody mess out. i used a shower head to gently wash the dirt off, this is a very slow and gentle process!!! then i clean the bath and got rid of the dirt, this is a very slow and boring process!!!! i was putting it into a 5" x 5" net pot for a homemade 15 litre dwc set up. i cut all down the side of the net pot and halfway into the middle of the ass of it where i cut around 1 square inch of pot away allowwing the roots to go thru then i just filled the pot with hydrton pebbles and put it in my dwc. its still alive 2 weeks on but hasnt grown much. this is a result of my lack of knowledge on hydro nute feeding , the fact the plant had been badly burned beforehand an also sheer bloody shock to the plant. the roots are growing though and i just KNOW shes gonna make it, maybe not yeild much but hey, its better than nuthin.
