How To Calculate Your Order Quantity
Step 1) In order to calculate how many individual grass units you should order, you first need to know the total length of the barrier you are wanting to establish (in linear feet or meters).
Install in a Row
You can use our Hot Grass to create a long line or row of coverage, such as along the edge of a moat or atop a ridge. Tip: A meandering line of Hot Grass looks much more natural than a perfectly straight line (as shown in this illustration). Measure the total length of that meandering line using a soft tape measure or CAD file if you have access to a drawing of the space. Once you've discovered the total length of coverage needed, use the formulas below to determine how many units you will need.
Install in a Loop
You can also use our Hot Grass to create a continuous loop of coverage around a tree or landscaped area. Start by measuring out at least 3ft (1M) from any branches or plants, so that the hot grass blades don't come into regular contact with the landscaping. Then, create a meandering line around the tree or landscaped area using flags or marking paint (or using the soft tape measure itself) and find the total length. Finally, use the formulas below to determine how many units you will need.
Step 2) Once you know your total length of coverage, you are ready to calculate your quantity. A single Econo Hot Grass unit spans 2.5 linear feet or .75 meters, while one Tall Hot Grass unit spans 3 linear feet or 1 meter. Attach multiple grass units together using the provided metal crimps to create a continuous electrified loop or row. For more information on how to connect units together, see our Hot Grass Installation guides. To calculate how many Hot Grass units you need, use the formulas below:
Econo (Short) Hot Grass
_______ (total linear feet of coverage needed)/ 2.5 (ft. of coverage per unit) = ________ (total # of units needed)
_______ (total linear meters of coverage needed)/ .75 (meters of coverage per unit) = ________ (total # of units needed)
Tall Hot Grass
_______ (total linear feet of coverage needed)/ 3 (ft. of coverage per unit) = ________ (total # of units needed)
_______ (total linear meters of coverage needed)/ 1 (meter of coverage per unit) = ________ (total # of units needed)
Hot Vine Lengths For Trees
When determining your Hot Vine length, keep in mind that to look most natural, the vine should not be wrapped around the tree in a tight spiral (like the stripes on a candy cane). Instead, plan for a little extra length so the Hot Vine can gently meander up the tree like a natural vine would. In our experience, most trees require 20-30ft of Hot Vine.
For larger trees or for walls, we recommend cutting the vine during installation, so you have one central vine that curves its way up the tree trunk or wall with smaller branches of vine attached to it. For more information, see our Hot Vine Installation guides.
Please note that because of how they are manufactured, hot vines only come in 15ft and 20ft lengths: So, if you order 50ft of vine, for example, it will come in (1) 20ft and (2) 15ft pieces. Because cutting the vines into pieces is part of the usual installation (and vine pieces are easy to attach end to end), this isn't typically an issue. If you need vines made in specific lengths for some reason, contact us for a custom order.
