Make small holes along the lid and pass a string through it. Some people use hooks. You can also weigh down the mains with objects.
I have done both.........I have used fishing weights before to weigh down........but I prefer to tie them down
Technically mainlining is just 2 way. 4 would be a quadline. And 6 like I usually do would be a sexline lol. Going for 4 next time aswell though. Looks tidier and easier than my usual method.
If you are looking for something to tie down the plants to the bucket lid, I get adhesive cable management clips and stick them on. They hold up very well even with the humidity and you can get a 50 pack for a few dollars on amazon. Sent from my SM-N960U using Grasscity Forum mobile app
