As far as your question......

Whatever tool you use, make it quick. Make the cut happen in an instant. Sitting there hacking a real branch with an Exacto Knife may take longer than a split second.

It needs to be fast and clean. And MB is right....leave some branch. No salve is needed for the wound as far as I know.
HARDDON Reviewed by HARDDON on . HST Question is for Zandor or anyone whoâ??s done pruning. H-man? Pics show first grow box with plant 30 hours into SCROGinâ??. Still 24/7. HST?? Yeah. Cause it was like tieing a screaminâ?? toddler into a crip. Heart ached at every tug and pull. You can see by other pics it looks like I should have plenty of room to try a few clones. Will have to rework lighting and put in a partition. Including pic of blower I got for $17. Should work good after one end of intake is taped off. Rating: 5
