i have been doing an experiment of coco vs soil...although with such a small number of plants, this experiment doesnt give us much data. i have tested one jack the ripper in soil against a jack the ripper in coco coir. i have been using gh gro, and maxi bloom. i have yet to add kool bloom. plants are just getting ready to start week three of 12/12. other additives include cal mag, humic acid, mycorrhizae, hco snow storm, and gh floranectar. ive been using a 400 watt hps, and water straight from tap. i have been watering every 5 days because plants are in 7 gallon pots. plants were treated exactly the same. DO NOT USE THIS POST TO JUDGE BETWEEN COCO AND SOIL...UNLESS YOU ARE NOT GOING TO USE COCO SPECIFIC NUTRIENTS.
reasons to why i think soil plant is larger:
large pots which means less watering (coco should be watered more often)
not using coco specific nutrients
any others?
denser canopy
reaons coco nugs are SLIGHTLY more developed:
less main colas..less competition
less dense canopy...more light penetration
here are a few pictures showing comparison...take a look and tell me what you think. these pictures make plants look real close to the same size. pictures dont show true comparison...in real life soil plant appears to be waay more denser than pictures can show.
