![]() ![]() Hydroseeded lawns germinate faster, and the slurry blocks the germination of weed seeds in the soil. And while it’s more expensive, it’s worth it to many people to have a lush green lawn within a few weeks. Hydroseeding provides better, more consistent results than traditional grass seed planting methods. Discover more about the benefits of each type before you decide which is right for you. With seed vs sod, how do you decide which is better? The main differences relate to budget and timing, but there are advantages to each method. Sodding your lawn is another DIY-friendly project, but it’s physically challenging, so it helps to have help from friends or family. It takes about 2 to 3 weeks before sod is ready for foot traffic, but it looks like an instant lawn. You need a smooth, compacted surface to lay the roots flat and make good contact with the soil. Ground preparation for laying sod is the same as for planting grass seed. So, keep that in mind as a scheduling reference. The best time to hydroseed is when the conditions in your area are ideal for planting grass. The mix also contains additives that help the slurry stick to where you spray it. The mulch is typically a wood fiber or paper cellulose product that protects the grass seeds. When hydroseeding, you spray a slurry of seeds, fertilizer, mulch, and soil amendments onto the prepared ground. So, if you need a thick lawn fast, how do you choose between hydroseeding and sod planting? Discover more about each of these methods before comparing hydroseed vs sod planting. ![]() Both of these methods work better to establish a lawn faster, resulting in fuller, thicker lawns. Hydroseeding and sod seeding are two alternatives to the traditional lawn seeding method, where you plant grass seed directly on the ground. ![]() Learn about the pros and cons of each method, and get answers to common questions about hydroseed vs sod planting. Five 3.6V, 2Ah batteries connected in series results in an 18V, 2Ah battery (FIG 3).Hydroseeding and sodding your yard are two of the best ways to establish a green lawn. All 5 are connected in series so their voltage is combined, but not their amp hour rating. What makes a 2Ah or 5Ah battery?Īn 18V (or 20V Max), 2Ah battery, for example, has 5 cells in it and each one of those cells is a 3.6V, 2Ah cell (FIG 2). So, you may draw 5 amps for 1 hour, but only be able to draw 10 amps for 13 minutes, for example.Įven if Peukert’s did apply to your cordless tool batteries, the companies that make those tools and batteries all source their cells from the same manufacturers, so they would all have the same charge/discharge rates anyway.Īll that to say, you can pretty much make a straight comparison that any brand’s 18V (or 20V max) 5Ah battery will hold more than double the charge of any other 18V (or 20V max) 2Ah battery. Peukert’s law, however, explains why that is not true for lead-acid batteries and the more you draw from that type of battery the less charge time is available. Taking our 5Ah battery above it’s easy to say that we can draw 5 amps for 1 hour – 10 amps for 30 minutes – or 20 amps for 15 minutes, in a linear calculation, and in fact we can with a lithium ion battery. Lithium-ion batteries have a self-heating characteristic that raises voltage and counteracts the dissipation of power due to internal resistance. Peukert’s law says that a battery’s amp hour rating is reduced disproportionately as more current (amps) is drawn from it. You may hear something called Peukert’s law, which is applied to lead-acid batteries (the battery in your car), falsely applied to lithium-ion batteries like the ones shown in this article and video. You’ll be able to use your drills, circular saws, and jigsaws longer before the battery runs down. Just think of amp hour as a way to know that one battery holds more of a charge than another. We say a capable charge because in the real world, you never meet those ideal conditions. Now, that’s under ideal conditions, perfect temperature, no vibration, and consistent power. Theoretically, we can draw 5 amps, continuously, for 60 minutes before our 5 amp hour battery is drained. Usually, if a battery has at least a 4Ah capacity, it will be prominently displayed somewhere on the battery like the 5Ah in the picture.Īmp hour describes the capable charge of a battery. Amps are used to describe amp hour, but they are different units of measurement. What is Ah (Amp hour)?Īmp hour (Ah) is a unit of measurement that has nothing to do with power and it’s a totally different unit than Amp (Ampere). Wondering what in the world Ah (Amp hour) means? Is a 5Ah battery more powerful than a 2Ah battery? Does it last longer? The video above and this article give a quick and basic explanation of Amp hour and how it affects your cordless tools.
