3 biggest PAINS

I am doing a course on urban agriculture at Wageningen University and I am analysing about difficulties to start growing your own food:

What are your biggest pains as a newbie to get started growing your own food/supply?

Thanks for your responses, they will help to make our cities greener

Well then, around here, I find that most "newbies" take advise from others or web sites. The advise is wrong or above their skill level or are taken in by wild nutrient makers claims. They then have problems and return to sites like this for answers.
The thing being they should have read quality "how to" books, and I do mean BOOKS, not just one. Then maybe grow an indoor plant and learn from that. Then attempt to tackle the plant they intended to grow in the first place AFTER having gained some real world knowledge about growing.

The "I want it now" and the "I want the biggest and strongest result possible" attitude (or mind set). Gets in the way of actual results and the learning curve required to succeed. One step forward and two back don't help much!

The idea that time is a problem, just shows that problem I stated above is real.

The ones that take the time to research and learn or understand the basic's always come out ahead. Their results they share here,,,,,SHOW IT!

READ, study, grow, learn, adjust, grow!

Yesterday I had a walk in Amsterdam asking 6 seed vendors:
Is it easy? Tipical answer: Yes, very easy, you can do it with closed eyes
Can they be inside my room? T.A: Yes, no problem, is better sun but you can also grow it inside your room... was hard to fake a credible face

Can I call you if I have problems? T.A:Well, all the information is on the internet, everything is on the internet.
Any special web recommended? T.A:Just google
Do you have any sort of mini-instructions to get started? T.A: No

so basically this generates what you pointed @Dr.Who ... People getting advice above their skill level (considering loads have never grown a potato)

Dr who is absolutely correct a little first hand knowledge combined with the power of the internet has made growing 'mj alot more achievable.the probs u stated at the start of this thread are all real and every noob will experience them at some point but the difference is how the individual copes and reacts with these problems that will inevitably lead to success or failure.I totally disagree with the stigma that mj is a WEED and therefore easy to grow this is totally not true unless and individual is total committed and at least eager to have the time and patience needed to complete a grow then they should stick to paying ridiculous prices for the thing they either need (medicinal)or just simply enjoy....
