what should i do then because my bubba is almost popped out of the top of the root riot cube? the taproot will probaby be poking through the cube by tonight or tomorrow
To be honest dude I wouldn't take the chance in work we get bags of coco to use to absorb spilt chemicals one of the lads tried to grow in it fried his seeds and it costs more than the stuff I use to grow starting it in a seed soil should be fine @stepside the man to speak to about the best time to transplant oh and subbed up good luck with your grow [emoji106]
I would guess it would be fine as long as all the salts are washed out.Ive used some coco in block form that was over 600ppm before rinsing but it doesnt take a lot of flushing out.
im not taking any chances if i dont absolutely have to... i went out and got some jiffy seedling starting mix with is pretty much just peat and perlite with MINIMAL nutes 
ill will wait for @stepside recommendation for transplanting her. she will be placed in a 15oz pot that i have laying around
yea i wasnt sure if that was buffered which is why i figured id ask to see if anyone used it. Glad to have ya along for the ride my friendlittle bit of light reading for you http://www.growstone.com/wp-content...ng-coco-coir-v2-Nate-Edits-Paula-Edits-v3.pdf
basically if you cant be sure the excess sodium and potassium is removed (can not be done with flushing) you will get nute lock the only way to buffer coco for growing is saturated with a solution of calcium nitrate to displace the potassium and sodium unless you can guarantee this has been done you could run into trouble
