Netafim, IRS, Wanna discussed on The Sprinkler Nerd Show
For drip systems will ninety five percent of the time. Let's say but the reason is is I really like. They're building admit irs. That's one reason we welcome you in the door back at Hydra. Tech is that built a mirror in the anti clog mechanism. I forget what it's called and also I believe they had some type of I don't know if it was copper hydroxide or something in the mirror. Federal intrusion on the technology. Yeah right yeah. So they roots can grow into it than the low flow. The really low slow you know in the spacing on the tubes. Those are all things why why we originally met at so. Let's just say that. Yes Netafim can also be like Kleenex in. There are lots of similar products and we can all have favorite. So what I heard you say. Was you like drip overall you. You liked the built in amid technology. You prefer something. That has inhibit root intrusion. And you're liking low flow emitters which I would sort of stereotype as a point to six point. Four anything point six point nine and we'll be high flosse's at sound right in terms of your in. Typically I like twelve inch spacing on the mirrors. Come in that twelve twelve twelve inch spacing on the tubes and then twelve inch between parallel lines. And you try to stagger those emitters in a triangle. Sort of spacing. Yeah because one of the challenges is as we talked about this growing media earlier and that growing media is very very porous. There's a high percentage of most green roof growing. Media's is lightweight aggregates that aggregate is clay or shale or slate. That's been heated in a furnace. The very poorest product in it's lightweight it's traditionally used in lightweight concretes in the industry sort of broad over to the growing media because it's very effective product still the volume regardless if you're within an extensive or intensive it fills that volume or that space in the depth of the media in allows water to freely drain through it and there's poor horizontal movement though which is the challenge of wire so when water hits it it goes straight down for the most part very little. Let's say in the industry very poor. Capillary water xactly. So that's one reason that a lower flow amidror is better because it's not dishonest outright away it gives it a little bit more time to expand and then saw in my experience right which is counter intuitive to what a lot of hear gator's think if you think sand a lot of year gators and a lot of what we're taught is sand would be point six point nine and the clay would be point two six or a point four but you're exactly right for my experience if you. WanNa move water laterally. It doesn't matter the soil type. The concept remains the same low flow and perhaps even pulsing. You need time on your side to move that water laterally longer run. Times isn't things that I could longer cycles in. Maybe back to back cycles to potentially you know maybe you run it for. Let's just say two hours in the morning in two hours a night but then you don't water for three or four days right you let that water saturate because the capillary action. If the sponges completely dry you want to wet the sponge so then the water content horizontally moved versus pruitt correct. Because if you had that dry sponge and this may or may not be an exact analogy but if you put that dry sponge under your kitchen sink and you turn it on the water. Just Poo pours over. The sides wants to sponge. Slowly absorbs now it can absorb more water through the bollock holding each other in place right. You have tighter phobic to start cracked it so sort of like a really really dry house plan in you you water in it all runs off on your bookshelf below Give it little drinks. You know you need to like poor. Little bit of water in their leaded Saturday into the soil than a little bit more. And then the next day when you water you could a whole glass. On of water onto their INNOVA. None of it runs off. So I'm just curious 'cause you can achieve that concept with overhead as well either through traditional spray heads or rotors or rats precipitation products like the MP rotator or routier nozzles. You could do a lot of what we're already talking about. If you properly schedule and program your controller are there specific benefits of the drip beyond the things? We've talked about that for reasons that you like it. The major one is over spray so if you have a green roof next to a big conference room full of eight foot glass panels in. It's windy all of a sudden overheads. Go up your whole windows pockmarked. With water stain right or the other way. It's blowing off the roofs on to you. Know the bankers coming into their office warning nor it's raining down onto the sidewalk below. Those are the reasons where traditional overheads may not be the best option. You could always go with low flow you know I really like to use. Misters plugged right into the drip to to accommodate. Water from above watering from above is a requirement of many manufacturers for certain types of plantings. Actually it's a catch twenty two of what well once. The roots are established after. I put the seat him carpet down. Drip is the perfect thing. It's really efficient. The root systems are right there but drip is doing nothing for side or carpet which is like Saad with cd-roms. It's doing nothing. The day of install it's running directly down. The roots are all up at the soil surface. So you need to water from above for a short period of time. A lot of ways in my experience that has done is temporary systems above your three quarter inch or one inch hose. Traditional Hose Garden hose with timers in a series of overhead oscillating sprinklers. The roots to push down into the growing media. And then you could on your Adrift System. The pop ups could be a part of that. You could have you know pop-ups with more Mr heads if you want to pop ups with the largest throes of water you know so. It's all really based on what kind of vegetation you have and maybe there's something that doesn't want water hitting their leaves. Yes so it's it's really a science sort of like you would do in the lands deep below. It does seem as sometimes the irrigation while all the time of year again is going in last end of the project in a traditional construction level on the ground and on the rooftop. Yup It's going in last and typically when a project goes in lasts if it's not already over budget they're reaching their budget and things can get cut and the system that may have been properly designed may give value engineered. Are there things that you see out there that if a contractor is listening to this and their general contractor someone is asking them to cut some things off of the system you know? What should they do you know? How can they respond to that? Well one way is to help. The general contractor is to guide them to make sure that there's water a water source in a power source at that Ruth. I can't tell you how many times a green roof has been designed and then there's no water on the rules. There's no no even hose bibs let alone a power source so a lot of times that's overlooked by the design community and the general contractors. Is that how do we get water? Power to control around the rooftop and to manage to Syra Gatien system. How do we do that? Obviously it's lot easier when the building's being framed or concrete structures going up. Yeah and some of these. You may need to put some slaving in the concrete between area one and area to area three for the piping needs to go in later. Europe so being proactive at the early pre time meetings is critical in also. You know calling that out in your proposal I understand that you know. An irrigation. Needed IRRIGATION. Sleeves are needed. Or what have you but if you get to the point where almost leaves her there? And it's time to put the irrigation system in one way to really reduce costs in maintenance is to consider there's enough volume in pressure at a hose. Bibb to run a traditional Mr Drip Combo. You know maybe the control box you know the wire that's going to be run to three floors down onto the utility room and the backflow preventer and all the copper fittings in all that that would be needed to run a traditional irrigation system. Maybe that is all cut. But they'RE STILL DRIP IN MR option to hell that there. But another thing is to point that contractor in her owner back to the specification that they paid an architect engineer or landscape architects to create in point to the warranties of the systems they selected is many green roof manufacturers and suppliers out. There that will not warrant the plans they provide to you. You know if you don't have a very specific maintenance protocol happening one of the number one things on a maintenance protocol or plan is your Gatien. Or watering so in that watering is most critical during the establishment period of those plants. It's when you take your plant and you put it onto the soil or into the soil. I think of it is. How long does it take that plan to push their roots into the growth media can then become independent of you? Know watering from above or you know There's an establishment period that is critical for success. And what are you seeing in terms of the time now I have a roof is a little bit different. But is there an average time period that you're seeing that you recommend to your clients? I'm trying to remember. It's probably changed in the last seven years books when I helped create higher-tech Smeeton Protocol I believe we looked at it to be first year. Twelve to twenty four months is establishment period. Okay but that can be much shorter. You know if you plan April in Michigan. Those plans are going to be pretty rooted in by the end of summer with the primary education. You might be on the back irradiation down. Take off your temporary irrigation system. But that's up to the greener professional working on the roofs to then assess at in reported back to whoever the warranty organization may be got it. Yeah that makes sense. Let's see if there's irradiators listening that Wanna learn more either about Green Rear Gatien which I don't know that there's much out there you know maybe you and I should work together to some more good documentation on it or just a green roof industry in general where they can learn about the types of green roofs and how the installation process works. Or maybe how the. Yeah the construction timeline works. What kind of resources are out there? Well there's always the Trade Organization. I know you've spoken with them. Visited some of their events in the past roofs for healthy cities chem. They have a training program to become a green roof professional. It's three to four. Different lecture series are sections. And then you can take a test to become a greener professional breeders. One is the basics in. I believe there isn't irrigation section in there do you think it would be beneficial for either negation person or negation company to become a green roof professional. Would that help them stand out in the marketplace? Is Someone who understands the industry? Yeah I think that There's many people that carry that designation in one of the first to get it back. I believe I don't even know at this point about twelve years ago or maybe ten but yeah definitely seen recognized. You'll find it investigation. Sometimes that the installer Muskie. Gr Appear Green roof professional from irrigation standpoint. That would definitely from manufacturer corporate representative having the GOP would definitely resonate with the manufacturers..
