KnowsGrows easy soil for beginners.

ORGANICS
This soil mix can be used for every cycle of the life of a plant.

1 part organic perlite
1 part organic vermiculite
1 part ROOTSORGANIC POTTING SOIL
For the final pot that the plant will be used in, mix in 1 part WORMCASTINGS

This mix works best with HPS and MH indoor grows.

you mean organic wormcastings and organic hps and mh right? because my hps isnt organic due to it costing like 100$ more.

What does the type of lighting have to do with organic soil? Nothing! Might be a good mix, I've never tried it, but don't say that it works better with a certain light type.

I've read in many threads on here that LED grows require more CalMg, so I can see what he is saying about how it works best with HPS/MH because his mix doesn't have added CalMg.

I have no words.....
