Are you not sure which controller would be a good one for your greenhouse? Say, I build controllers for a living and we have the same problem even within our company. What, what should people use? So, I, I just got done writing this little book with pictures to try to help guide people through what, what they'd be looking at. Start out with the, uh, the three main greenhouse controllers we've got. This is, uh, Ventstar. This is like the low end one. Here's all the advantages that that one has. And here's the Captain Eight. And this is the advantages for this one. Uh, you can download this book or just give us a call and we'll mail you one. Um, it's nothing real fancy. And here's, uh, the Captain 10. It's all the advantages. Um, if you notice, there's reasons not to use the vent store. Reasons not to use the Captain 8. Ha! We don't have any reasons why not to use the Captain 10. But anyway, I'll go through and show you what the main differences are. It's basically different layouts. You gotta look what your greenhouse is. We've got roll up sides of heaters. You go through it and find your style greenhouse in here, and then match it up, and that'll give you an idea of what to use. And I'll go over a couple things you might find interesting, like do you need humidity or not? So if you need, if you got wet leaves, rotting plants, bud rot. If you've got those, you might want to consider humidity and you'll want to use a controller that can handle the humidity sensor. And this will tell you, then when you actually are using it, these are all the perimeters that you can adjust. You have, uh, you have problems with, uh, rain blowing in. Uh, you know, do you want to shut the vents when it's raining? Do you want to protect the crop when it's raining? You know, if that's important to you, check which controller can use rain. Same thing for wind speed. You know, if it blows apart when it's too windy. If that's a concern, check which controller can use that. Oh, and do you want to use time differentials? What's a diff? That could be a whole thing in itself. Basically offset the temperature at a certain time of the day. And yeah, it's just 30 pages long. And it's pictures of the wiring sketches of how you'd wire your greenhouse and which controller would make the most sense. So each one has the setup perimeters. So if you had this and you had a controller and you had this, This will show you the exact setup perimeters to have the controller do that just for you. So that's the idea. If you've got questions, we can send you a hard copy or send us an email and we'll just email a copy over to you. It's not much to it. We just print it out and send them out as needed because it's a constant dynamic as we make updates that'll be in here. So if you've got questions, give us a call and we'll help you out.
Here is what we're doing, Its not all the best I live on my family farm. We have 180 cows . This is our heifer barn for up till breeding age. This building is 60 feet long, 30 feet deep. It holds from five months to breeding age heifers. Around 45 square foot per animal. , you can see they've got manure on their sides because we had a bunch of wet weather, and this is overcrowded, we are not ideal. But what we're doing to get away with our problems is the building isn't real deep and we have pasture access. So if it wouldn't be for that, we would have problems. It gets really soupy in here quick. We try to leave them have pasture access we keep them in pretty soon if it's wet weather. So we don't turn it into a mud hole and chew up the Creek bank. if you got fans, it'll help keep it dried out. One fan can cover a big area, but not when you're overcrowded. You need to have them closer together for cold weather so you can keep the air slowly moving. We keep that fan running down to freezing. We should have two big ceiling fans to keep even amount of slow moving air going all the time. We have a curtain on the back. We leave it up all the time because we're overcrowded. We only put it down when it's really bad weather. It's got to be raining really bad or really windy and cold. We have a four foot wall in the back that blocks some of the wind, but we err on the side of keeping it too cold because of how overcrowded it is, You've got to keep the air moving. You've got to keep the curtains open. And your building can't be too deep. we are only 30 feet deep. The air gets nasty really soon. If you had a hundred foot deep building and a lot of wet bedding in there there's almost no hope. But with a narrower building, the stink blows out easier. If you want to overcrowd a facility make sure that it's narrow enough so that there's fresh air blowing through.
📍 We're here at our family's calf barn. . Right now it is in January is 20 degrees and It's cold. The buckets are all frozen up, but we, and this is simply an open front with a plywood dividers, wind breaks in between every 12 foot. To keep the wind from blowing sideways across the calves. Oh, we have to keep the bedding dry. We're replacing the bedding pretty often. If we're not overcrowded, we're cleaning out once, once the calves are out of here, which is whenever they're off milk, but we've got two curtains on the back and those are set, the top one will open, start opening at around 22 degrees. As long as it's not windy, then the bottom one will open it around mid thirties to 40, if it's not windy. So. I actually built this ventilation controller, one of the first ones ever made. And, so as long as it's not windy, the curtains will open up when it's pretty cold. Because calves need fresh air. So that, the whole idea of what I've been working behind is natural ventilation. And if it's not windy, you want fresh air. And it's still better than if you had a completely closed barn. You don't get any sunlight in. So from a disease standpoint. This would be better. A closed barn would be warmer for the people, but friendly for the people and healthy for the calves just don't seem to go together very well. Winter time, heifer barn management. See, I'm here at our family farms, heifer barn. It's a, it's got the heifers that are about five months up till getting close to breeding age. There's a pastor out back there. It's cold right now. And if you can see it's overcrowded They're a little dirtier than what they should the management here isn't quite good as what it should be But anyway, there's a single curtain on the back that is supposed to start rolling up around Freezing as long as it's not windy So I got my start doing ventilation controls all for natural ventilated barns because that's what we do here But if you look at this one of the thing from a curtain management standpoint There's holes in the back because we don't have we're leaving the heifers lick the fabric at places or they can get to it at places And they'll chew through it fairly quickly. It's really tough to keep a curtain functioning if animals can get against it. So if you're trying for longevity on your curtains, on your heifer barn, do not let the heifers be able to lick it because as you see here, it makes holes in it and it's really hard on it. So we believe in the cold weather philosophy. We do not keep them closed up. The front's open. We're here in Pennsylvania right now. 20 degrees and a little windy. Simply getting them out of the wind is what we're trying for. If you're looking to automate a barn like this, we've done over 30, 000 control systems in the last 15 years and a lot of them are barns like this. We do fans and curtain controls. So in the, with the fans in the summertime, you can keep the bedding dried out when you're in the cooler, wet weather, if you run them slow or the real damp muggy days, you can prevent some respiratory issues by keeping the air moving the 20 degrees. Why we don't run the fans, but. They sure help cold weather, freestyle barn management. So here we're at our, here in my family's a freestyle barn. It's around 180 cows. They're milking around 105 pounds or so here in January of 2025. I just want to show you what we're doing. Right now we're running in natural mode, which means just with the curtains, there's no powered ventilation at all right now. And it's set to the defaults that we built our ventilation controllers at, which is the top curtain started opening around 20 degrees, as long as it's not on the windward side. So you can see the South side is open and the North side is closed. And the only difference is the wind. Cause I found out that. It's not the temperature as much as it's the wind. So if you want to try to keep your respiratory problems down, you'll want to keep the barn as cold as possible. This has not really worked well for robot barns, but if you can get away with it, leave your barn, get cold because you'll have less respiratory problems. So as, as a day progresses, the other curtains will start opening up as it gets warmer. Right now it's around 20 degrees and five miles an hour, kind of from the North. We appreciate you watching and hit like, as it helps us help more people. https://autoventllc.com
