Pippi, people can write and submit tips, articles and the like on any subject any time by using the gardening ideas link. However, someone has to want to write and article, etc. And writing articles and tours and the like can be a lot of work.
In the meantime, ask questions in the appropriate forums and you're sure to get some answers if you start a new thread with that subject line
e.g. post a new thread/question about cuttings on the propagation forum or
" one about cloners on the propagation forum
post questions about growing under lights and ask folks to post pics of their light systems. There's an old thread to that effect somewhere in the seed forum.
Questions are often lost in existing long threads, but if you start a new thread with your questions you're sure to get good responses.
