Coir Hempy works well. I've run with a hydroton res and am 6 weeks into bloom with a 60/40 coir/perlite hempy buckets with OC+. I've never run perlite only or perlite/vermiculite hempy buckets, so can't comment on a yield comparison.
One way you can gain a healthy attitude against expensive bottles of pre-mixed fertilizer bottles is to use the less expensive options. i.e. CRF and/or WSF.
Don't let them suck you in with fancy marketing!!
Amen!
I was reading Maximum Yield mag today, over lunch, and I wanted to go out and drop a grand on super duper nutes!
Then, my senses returned and I remembered that there's nothing at all special about super-duper nutes....except the price. But it's so hard to remember that our beloved plants aren't much different than other plants, and there is no logical reason to buy the same raw materials at 39 times the price.
I mean, Bud Candy? I can take what comes out of my horse's ass and impress people. I can also take the alfalfa meal before the horse eats it, and make a tea out of it that will make plants go crazy!
Kushie Kush? Give me a break!
I'll stick with my OC+ or dynamite! When not using those, I'll use my organic soil mix.
My garden is looking real good right now, and I haven't spent a dime on nutes...still working through my first bottle of OC+....lot's more to go.
