Canna Flush Help Needed

Hi Guys

Im a bit unsure how to use Canna Flush. I have a wilma 8 pot drip system. Im currently feedling by timer for 15mins in each hr and have lights on 24/7 - growing Autos.

How long before harvest day do I begin using etc?
The instructions on the bottle says start administering according to normal feed schedule with 10-20% drain the following day? I dont understand this

Also wondered what I should do when ready to harvest... keep lights out? Does lights out apply to autos? Do I hold back on feeding for last 24hrs, I just wondered with it being in clay pebble not soil if leaving pump off for that long could be detrimental to the plants?

Cheers

Anyone used canna flush??

i didnt know they had a flush... but i researched it and found the instructions you should follow... Canna them selves say to apply canna flush to your plants at a dosage twice the size of your root area. I.E. in a 2 gallon pot of soil, flush with 4 gallons of canna flush. in hydro just apply canna flush to your untouched water. dont ph the water. use canna flush for 24 hours. flush canna flush out with ph'd low ppm RO water. 24 hours later your ready to cut.

i mostly use canna aqua series and i flush for 7 days before harvest using 007ppm RO water. i check the ppm of the water every day. by that time of flowering (last week) i am already down to 700 ppm. at this point i dont even bother PH'ing my water. after the first day of flush its usually already down to 60ppm. i change the water again the next day and itll be down to 30. ill let it sit a few days at that then flush it one more time. the final flush is for the last 24 hours and the ppm goes down to 15 or so. i do not add anything to the water during the flushing time, so NO feeding during the flush. Harvest in the dark under a green light if you can... a green 100watt CFL bulb is about $5 at home depot. This applies to all smokes, auto or regular.

Thats brill dude thank you sooo much!!!!

Re the green bulb, is that to preserve the goodness in the plant when im working around it? i.e i dont need to leave the light on for the last 24hr, just have it on when im chopping it down or working in the room and want to see where im going etc?

Would something like http://www.lightbulbs-direct.com/pr...een/?ctype=2&gclid=CJL14N-t5acCFcJP4QodTFPJ9A do the trick?

the green light is so you can keep the regular lights off your plants. from the research ive done and from what more experienced people on here have said to do, im following this green light idea and im watching the humidity in my drying room. by doing this and also following the right burping regiment during jar curing, im hoping to achieve the best taste i can. as far as the green bulbs go, this is more like it... http://www.google.com/products/cata...=X&ei=gsCKTcKGNYzqgQfnk9HKAg&ved=0CFkQ8wIwAA#
