go off the website nutrient calculator I typed in my rez size and printed the chart, I would use the coco formula for coco. Why do you want to use soil?
well i grab the entire line off a dude on ebay moving and he was a hydo grower but i get co a, co b, root excul ,
top booster, liquid zen,
bud xl, drip clean a titan co2 tank a 9 light t'5 system a heating mat and a cfl fan and times , adjusters all for a cool 100 bucks , the chem themself were stickered at over 300 , just the root excul is 77 dollars and at hydro last week when i asked dude if cocoa would work in soil , i notice most of the stickr prices were higher than what i had , so why not grab it.... just the nice look of the bottles in my collection were worth a c note to me... hell would of paid 100 for just the light set .....
