My rule of thumb as to when to top is 'as soon as they are big enough to handle or cleanly snip'
FYI next time you are on your grow thread, copy the address at the top of the page
Then click on your name 'Olg g' up by the envelope at the top of any page to open your 'Profile'
Click on 'Signature', write a title, then paste the address you copied earlier into the box provided below that
Click 'Save'
A link will now appear below all of your posts, meaning people can drop by your grow and take a look, otherwise only those who perchance cross your thread will see, comment and follow it
It's a great way to share your experiences and gather opinions
