Good thread,i find myths here on a daily basis,they get repeated like bobble head dolls,the ole "what he said" factor which leads to noobs giving terrible advice.
1 Miracle grow.
All the rave is to repeat what "they've heard" about it killing grows,its been proven time & time again on this forum that the stuff works,noobs destroy their grow then blame the fert instead of being over anxious & using it in an improper way.
2 Fox Farms high priced soil.
Ive proven in a side by side comparison in my personal grows that the super expensive soil offers zero benifit over home depot brand potting soil that has been amemded properly, at 1/10 th the cost per pound.
3 Bud dryers.
My 4th grow using a bud dryer finished drying a few weeks ago with excellent results,after the 1st bud dryer grow i finished to be sure i wasnt taking away quality or taste with the bud dryer, i gave out samples of bud dried in the bud dryer & hang dried & cured bud as well,not one single person could pick out any harsh taste,headache or any other negative drawback,infact most people thought both types tasted the same as the other,both types looked excellent as well.
4 Exoctic fertilizers.
My personal favorite fertilizer for my soil grows is Peters/Jacks brand granular ferts,they were the ferts reccomended in the grow faq at Overgrow before it went down,a very high quality fert but cheap like Miracle Grow.
Ive tried them side by side with several different ultra high priced exoctic ferts like Fox Farms,the jacks fertilizer plants were in better overall health through the entire grow,i attribute this to me using peters & jacks for years & being a noob to exoctic ferts,the point is that excellent results can be had with no need to buy these super expensive products.
5 Seed bank seeds.
When i 1st got back into growing i did the normal deal & used bag seed from a bag of good weed without a fancy cool sounding name & it was mind blowing smoke when it finished up,my 2nd grow i ran 4 differnt seed bank strains,all of them turned out kick ass but none were better or worse than the bag seed grow before & i had plenty left from the 1st grow to compare against.
The point is that seed bank seeds do not need to be purchased over quality growing equipment,i see noobs all the time reccomending that other noobs must buy seed bank seeds out of their very small grow room budget, & reccomend buying better lighting/fans ect later on,this is not true,as long as the weed the seed came from was good the wee grown will in most cases be better.
Many more myths that get repeated daily as well,hopefully others will post.
