The benefits and drawbacks of forced ventilation

By definition, forced ventilation included an electrically operated exhaust fan at one end of a building and intake louvre at the opposite end.

The biggest advantage of this system is how simply it can be automated. Running your power supply through a thermostat will allow the system to come on and shut off at the set point.

There are numerous things which need to be considered for forced ventilation to be effective.

The prime consideration is proper sizing of the system. Most greenhouses require one air change per minute to keep the temperature within a tolerable range for the plants. Fans are rated for the cubic feet of air they can move per minute (cfm). By calculating the air volume in a greenhouse, you can then get a fan that is appropriately sized.

There also is a formula to match the air intake to the exhaust. When the intake is too small, the capacity of the fan will be restricted but if the intake is too large, it also is undesirable. A properly sized intake will create some turbulence so that incoming air is mixed with the existing air before it moves through.

Consideration must also be given if the intake has netting over it to control incoming weed seeds or insects. This will restrict more air flow than is usually expected.

The orientation of fan / louvre combination is important. If the intake is on a south facing wall, the incoming air will always be warmer than average. This means you will be moving warm air rather than cooling.

If a fan is blowing into a prevailing wind, the fan capacity can be significantly decreased as well. If you do not have a choice but point that way, it would be wise to consider a hood or other deflector over the fan.

When you are deciding on what size fan to get, it is often suggested to get two fans with that combined capacity. It will cost more up front, but the extra payback will be on extra flexibility or options for ventilating. This gives you the option of “half capacity”.

When planning for a forced ventilation system, it is important to understand the requirements and cost of getting the electrical service to that area and also what the on going operating costs will be. In both cases, these expenses can be significant.

One last thing which needs to be pointed out for consideration has to do with irrigation. In a forced ventilation structure, things dry out more quickly and they will also dry out unevenly. Just something to be aware of when you are thinking everything will get watered the same.

In our next article we will explore the opposite end of this spectrum … some of the options of passive venting.

Preparing for a Hurricane

To our east coast customers, please note, with Hurricane Fiona approaching, (and any in the future, as we’ve posted previously with Teddy and Dorian) there are some key things you need to do to prepare and give your structures the best chance possible of surviving.

  • It is critically important to inspect all the greenhouses and their anchoring systems.
  • If you have anything extra which can be used as an anchor … use it in the direction of the prevailing winds.
  • Make sure that there are no loose ends of wirelock inserts or any loose plastic coverings
  • Make sure that there aren’t any frayed parts to any ropes on the tunnels and that the ropes are TIGHT.
  • If you see things coming apart during the storm and it is still safe to go out,
    CUT THE COVER.
    It is easier to replace the cover then the whole structure.

If you have any questions or concerns, please email or phone us this week, we will respond to every email and please, most of all be safe, our thoughts are with you

We had previously shared this ahead of hurricane Teddy and Dorian (as many of you have found on our website already!) but it is all still very relevant ahead of any hurricane, as Fiona approaches the east coast. Please be safe and prepare what you can. We at Multi Shelters will hold you in our thoughts this week

Organic Greenhouses/Shelters-uses and benefits

smaller high profile

There are many benefits to having a greenhouse structure for organic growing and housing. They are often used a season extender for protecting crops from the elements, blight, and fungus. Since Organic growers and farmers do not use pesticides, this type of protection is often required for some of the more sensitive crops.

The structures are easy to move to allow the expansion of the growing area.These structures can easily help to give you the opportunity to grow more crops in a limited area. What many of our customers also do, particularly with Hanley Caterpillar structures, is start growing the early crops under the protection of the structure, and as the crop is stable enough, they move the structure to be able to start the next planting.

Knight Hanley Structure

Our structures are also used for organic livestock raising to ensure the animals have a healthy, safe and protected environment out of the elements. They are versatile structures, and only require the changing of clear to white plastic for the various uses. The environment allows the animals to have sunlight, but still get the shade they require.

The combination of the double layer of plastic, roll up sides, and inflator fan, on both the greenhouse and livestock shelters, helps to reduce condensation and keep the structure ventilated. We are excited to be working on a solar powered fan option for those off grid customers or if the structure is out in the field away from electricity as we know many of our organic growers and farmers are in these situations.

Working with MSS and the New Electronic Log System

click to watch video

As we mentioned in a previous video, MSS is known for working with its customers to keep down the cost of shipping. That was all about the communication process before the load actually left.

Today we are discussing how and why we need your help during the delivery run: the new reality of trucking is ELD (Electronic Log devices)

Historically, our driver has had to keep a paper log of driving and deliveries. This was to ensure that there were no more than 14 hours per day or 70 hours per week of working and driving.

The system was cumbersome but at least there was some wiggle room.

With the new electronic system, there is zero wiggle room. It must be turned on before the driver starts moving and literally every minute must be accounted for. When the 14 hours is up, the driver must be stopped; there is no allowance for doing an extra 20 minutes to the motel.

If the officer asks for a report, it will be right there that the driver was illegally moving. The fines are extremely high and the driver’s record will precede him. Many of our stops are rural and remote. Often the driver stops early just to play it safe.

The driver must be very efficient with his time and here is how you can help:

  • Let us know if there is anything going on in your area on the roads.
  • Make sure the address and directions we have are accurate.
  • Have your area for unloading ready. Lumber to lay things on should be nearby.

Losing time to these kinds of things can mean that the last drop of the day is pushed back until the next day. This will add to the delivery runs’ expenses and must be passed on to the customers. We do not do our deliveries at a profit when margins can be sharpened.

We enjoy making connections with our customers. Unfortunately, the driver simply does not have the leeway to chat as much as previously.

We appreciate your help and participation in ensuring a smooth flow.

How MSS Coordinates Deliveries & Back Orders for Top Customer Satisfaction During Challenging Times

[click to watch video]

Working With Our Customers for Mutual Benefit on Deliveries

Multi Shelter Solutions has always been known for working with its customers.

This is particularly true for coordinating deliveries to minimize freight costs. It is more than just saving on freight, though.

Our deliveries ensure that the product gets to you when it is supposed to and in the condition it is supposed to.

Occasionally we are faced with a situation where a shipment is not complete at the promised delivery date. It has always been our policy to still ship the order with the back order going out at our expense.

We deem it more important to keep you happy and on schedule than worry about the additional expense.

We know it’s well known, but with fuel prices going up at unprecedented rates and supply chain issues ongoing, meeting this commitment has become even more of a challenge and required more creative solutions.

It has also emphasized how critical good communication between all parties is. You need to have timely and accurate information on your order status and we need accurate information on your schedule.

It is pointless for us to show up with an incomplete order when you are not ready for it.

We hope that we have built up a level of trust where you feel comfortable giving us this information, while knowing we are working hard on your behalf.

Through good dialogue, we can minimize the impact of these delays for both of us.

We appreciate the trust you have shown in us by placing your order with Multi Shelter Solutions. We will always look forward to working with you on your project through to completion and in the days that follow
