Certain Products have Minimum Shipping Level Requirements:
These products will be listed as such on the product page. If you select a shipping level below the min required level, the shipping will be adjusted and the shipping cost will be adjusted accordingly. This is typically required for items that are perishable and it’s non-negotiable.

During periods of high temperatures, we will require next day shipping but we will split the freight with our customers.
This is to guarantee the bugs arrive alive. It’s the only way when it’s hot.

All living beneficials WILL be sent by
2 Day Air or NEXT Day Air Only!
All orders sent direct from the insectaries will be sent by Next Day Air Only!

If you see a message like this one:

Galendromus occidentalis are sent direct from the Insectary Next Day Air.

Next to any product, this means that the item will NOT be brought into Hydro-Gardens and will ALWAYS be sent direct from the insectary. All of the insectaries ship their products by Next Day Air ONLY. We have no control over this. However, the insectaries are willing to reduce the Next Day Air charges to get them closer to 2nd Day Air rates.

The reason for the Next Day Air ONLY rule from the insectaries is to guarantee that the product is in the best condition possible. Most of the beneficials that fall into this category are very sensitive to heat or cold during shipping. Again, there is nothing we can do.

If you have any question about this information or anything else, Please feel free to contact us Toll Free  888-693-0578

The shipping weight of beneficial insects is given on the web site but shouldn’t be considered accurate if you buy more than one item. The reason for this is that we can put several types of insects into the same box and still have it ship at one pound. Example: if you were to order 1mil Nematodes they would ship at the same weight as if you ordered 6 @ 1mil. So you can see there is no way of accurately estimating the shipping weight. However you can be relatively sure that most of the orders will ship at the one pound rate. If you have any questions about this, please feel free to contact us and ask.

Limited Warranty On Beneficial Insects

Hydro-Gardens will guarantee the insects will arrive alive to you. On the rare occasion that part or all of a shipment arrive with dead beneficials, we will replace them one time. You are required to notify Hydro-Gardens within 48 hours of delivery. We will send a replacement as soon as possible.
If you don’t notify us within 48 hours, the guarantee will be void.

Hydro-Gardens tenders freight to the carrier in good condition. It is the responsibility of the carrier who acts as your agent to safely deliver your shipment. It is imperative that you examine your shipment carefully for damage or shortage, and have the driver note any discrepancies on the bill of lading. Do not refuse any shipment that has damage or shortages, as this is your property, and refusal causes unnecessary delays and storage charges. Arrange with the carrier to have damaged articles returned marked “Deadhead For Repair or Replacement”. Hydro-Gardens will be glad to render any assistance necessary to trace and recover lost goods, and will work with you and the carrier in resolving damage claims.


American Coolair Shipments: American Coolair has a very strict ZERO TOLLERANCE shipping policy. If you don’t inspect your entire shipment and get ANY damage noted on the B.O.L. when it arrives, you will NOT be able to file any claim and they will absolutely NOT pay for any replacements. It’s very much a “Caveat emptor” (let the buyer beware) situation with Coolair. Here is a copy of their policy that you MUST be aware of and follow 100%.

“Responsibilities of the Consignee

Important rules that the customer/consignee who is receiving a shipment of freight from American Coolair must follow:

  1. On arrival, immediately inspect the shipment for signs of damage.
  2. Compare the actual number of shipping units to the number listed on the delivery receipt.
  3. Be sure to note any damage or shortage exceptions on the delivery receipt.
  4. Sign the delivery receipt. Be sure to make note of any and all signs of possible damage as well as the number of pieces you are receiving.
  5. If the shipment has a large amount of damaged pieces, refuse the shipment or the damaged pieces.
  6. Notify (Coolair Rep Name Here) immediately of any damages or shortages. Failure to do so will delay replacement of the missing or damaged items.

A signed delivery receipt with no exceptions is called a “clear delivery.” Clear deliveries mean that there were no shortages or visible damage at the time of delivery.

American Coolair Cannot File Claims For Damages Or Shortages On Shipments With Signed Clear Delivery Receipts. The Consignee may file a claim for hidden damages on a clear delivery but the freight lines will usually only pay a portion (1/3 to ½) of the claim amount. The bottom-line, inspect and count: if in doubt make an exception. It is so important that the consignee be aware of these responsibilities that I am including an attached word document with this information. Please put your company name in item number six and send this out to all of your customers.”

This policy is their policy and Hydro-Gardens will not be able to supersede this policy. This is a risk that you incur when you purchase any American Coolair products and you purchase them knowingly accepting this responsibility.

Our catalog may be your key to success in this business, including Wholesale Hydroponics Supply and Hydroponics Garden Supply. It has been said that Hydro-Gardens’ catalog is “the most instructional and complete catalog ever published”. Not only do we list everything you need for vegetable production, but we tell you how to use these products effectively and efficiently. We blend hydroponic nutrients for specific crops; not one blend for all crops. These low salt index formulations provide a higher concentration of usable plant nutrients than any other available. You will generally use 1/2 as much Chem-Gro for your plants as other fertilizers. This savings can be significant over the life of your crop. (About $0.55 per plant space per year) Because we use only the very best ingredients in the correct proportions, you will find you greatly reduce the level of additives other suppliers suggest you add to their fertilizers.

As you read through our catalog, keep in mind that every product has been thoroughly tested and proven. Each has been selected for you by us because we selected them for our own use first. We’ve worked with every item shown on these pages. We’ll help you put in your system as if it were our own. We know that our continued growth is tied directly to your success.
