Delivery and Shipping

Shipping Policy

Notice: CHECK THE SHIP BY DATE ON EACH PRODUCT PAGE

Each product will have an estimated ship date and those dates are accurate and being monitored everyday.  

Below you'll find a detailed explanation as to what to expect for the different ways we handle orders. 
1. Order now, with ships by and delivered by dates available
2. Estimated Ship Date with no delivery dates available: We have manufacturers that will ship directly to you in the event we are out of stock. This means that we do not know exactly when it will ship but we encourage our partners to get the items out within 3 days. Occasionally this will take longer and is not 100% in our control. 



3. Backordered: This is because the product is currently in route to us or we are waiting on part of the item to produce. When this happens we still know what to expect with accuracy and will tell you when to expect the shipment.
 
 


BuildASoil Shipping and Freight Policy:

  1. If you select a service at checkout that is how we will be shipping.
  2. BuildASoil Shipping – We decide the most economic carrier. USPS, FEDEX or UPS
  3. BuildASoil Freight – All orders over 350lbs or a volume exceeding 15 cubic feet may utilize freight for delivery. Notice: To expedite your freight order, many of the smaller items will be shipped separately. The remaining larger bulkier items will be sent via freight. IF YOUR ORDER IS ONLY QUALIFYING FOR FREIGHT SHIPPING AND YOU BELIEVE THIS IS INCORRECT, CONTACT US!

Free Shipping? Only available to contiguous U.S.

Shipping Times: After Fulfillment

  1. BuildASoil Shipping – 1-5 Days Shipping (USPS, Fedex, UPS)
  2. BuildASoil Freight – 1-7 Days Transit time depending on distance. Please note that the estimated delivery on freight shipments is the estimated date that the shipment will reach the nearest terminal to your delivery location, and final delivery can take anywhere from 1-10 business days following the delivering terminal receiving the shipment. The carrier will reach out to you to schedule final delivery. Please input an accurate phone number and shipping address during checkout for delivery. 
  3. Specific shipping selected at checkout:
  4. Overnight – Will ship out same day or next business day.
  5. 2 Day Shipping – Will ship out same day or next business day. 
  6. Specific Carrier Selected and Paid for: We will use your selected carrier

How is shipping calculated?

We use the product length, width, height, and weight. We send this info through a custom system that calculates the absolute best box to combine your items into. This box and weight info is then sent within seconds to the carrier and back again to display the real time rates. We do not ever add money to our shipping rates. 

How does freight work?

Freight shipping is our go to shipping option for when your order has become too big to ship through ordinary parcel. With freight shipping, your order will go onto a box truck or semi trailer. Depending on whether you are a residential or commercial customer, we will make sure the proper accessories are selected from our end to make delivery as easy as possible for you! With a freight delivery, the shipping carrier will contact you and likely schedule a delivery appointment to make sure you are there at time of delivery and can sign for the shipment.

Do not sign for your order until you have confirmed an identical count of boxes, bags, rolls, bundles, pails, etc. and have checked very carefully for apparent and/or concealed damage. We will not accept any responsibility for missing and/or damaged items unless you note a count discrepancy and/or identify damage on the bill of lading at the time of delivery!

Tracking and Receiving Orders:

All orders shipping via FedEx or USPS, you will be provided with tracking information via an email to the email address provided on the order on the day the order is shipped. Please contact us immediately if you think your shipment is lost or if your shipment arrives damaged.

When your order arrives, open the package immediately and inspect the content against the packing slip; it is especially important to check viability on living products immediately. Notify us immediately of any shortages or damage, do not discard any damaged items or shipping cartons. The shipping company may require an inspection prior to approving any claim.

Claims Policy:

Visible Damage, Concealed Damage, and Missing Content Claims - Visible Damage is defined as any damage to the packaging that is identifiable without opening the package at the time of delivery. Concealed Damage is defined as any damage that is not immediately noticeable at the time the package is opened or when the product is first used. Missing Content is defined as any package that is missing product that the packing slip states is included. These types of claims must be made directly to BuildASoil within 5 business days of delivery. Any claims made after that time cannot be honored. Please contact BuildASoil at 855-877-7645 or email Support@BuildASoil.com to make such a claim.

Incorrect Delivery and Lost Package Claims - Incorrect Delivery is defined as any incident where the driver delivers the package to the wrong address or individual. Lost Packages may occur in two ways. First, lost packages may occur when packages are not able to be located within the carrier's network. Second, a package may be considered lost when the carrier claims delivery was completed by leaving the package on the doorstep, but the customer cannot locate the package. Both incorrect delivery and lost package incidents are usually discovered through standard tracking of the package.

Claims for either of these problems must be made directly to BuildASoil upon discovery. No claims will be honored after 30 days from shipment date. Please contact BuildASoil at 855-877-7645 or email Support@BuildASoil.com to make such a claim.

Incorrect Product Claims - BuildASoil must be notified directly within 30 days of shipment of any package received where contents incorrect. Please contact BuildASoil at 855-877-7645 or email Support@BuildASoil.com to make such a claim.

Shipping to Hawaii, Guam, Alaska, Puerto Rico and the US Virgin Islands:

Items are generally shipped to these locations via USPS or FedEx One Rate. Boat and Barge shipments for palletized orders are available. Call for a quote. Perishable items and beneficial insects cannot ship to these locations.

FREE SHIPPING ITEMS DO NOT APPLY TO HI, AK, GU, VI & PR.

Expedited Shipments:

All expedited shipments should be received in 2 or less business days from time of shipment

Partner Vendor Shipped Orders:

We sometimes allow vendors to ship product directly to our customers when it’s most efficient. These orders will often be delivered within one week of ordering, but in some cases these orders can take longer due to product availability and weather delays in which case we will email you to communicate.

Lightray Diffuser 🌟

Do you know what your PPFD and DLI are? 

Upgrade your smartphone to a professional light meter with the Lightray Diffuser & Cosine Corrector. Experience top-level accuracy and convenience, right in your pocket! 📱✨

We use this at BuildASoil and find it to be comparable to our Apogee Device that costs over $500!! This is fantastic!

Check out our tutorial on this subject: BuildASoil: HOW TO SET UP YOUR GROW TENT ENVIRONMENT // DLI, VPD, & More (Season 6, Episode 03)

NOTICE: Currently only available for iPhone 5S and newer, iPad models released after 2013

Notice: Must use with the Photone or LM-3000 App available for free. 

Do I need to pay for Photone?

No. But Yes. You can download and use the app for free. To measure your specific light accurately, you will need to unlock an additional light source which costs between $3 and $7 one-time and is valid a lifetime.

I purchased and use the Full Spec LED option. 

We also offer additional Pro features (all light sources, color temperature measurements, advanced settings, additional content, premium support) as a subscription for $5 a month or $30 a year that you may cancel anytime.

You won’t be charged anything without explicit purchase. With every purchase you support us in providing you with the best, most accurate and ad-free light meter app in the world — and also our planet!

Features 🌟

  • 📏 Best-In-Class Accuracy: Get precise light measurements rivaling expensive hardware meters.
  • 🔆 Excellent Cosine Correction: Ideal directional response for real-world lighting conditions.
  • 🔬 Swiss Quality: Developed and tested in a Swiss optics laboratory, ensuring premium quality and reliability.
  • 🔧 Easy Clip-On Design: Simple to attach to your device’s front camera, compatible with all newer iPhones and iPads.
  • 🛠️ Hand-Assembled: Each piece is carefully assembled and tested for quality control.

Benefits 🌿

  • 📱 Portable & Convenient: Carry professional-grade light measurement anywhere you go.
  • 💡 Enhanced Precision: Achieve uniform light diffusion for accurate readings.
  • 🌍 Global Compatibility: Compatible with various iPhone and iPad models; not yet available for Android.
  • 📦 Quick Shipping: Orders ship within one business day, with worldwide delivery options.

How It Works 🛠️

The diffuser uses a semi-transparent disc with a microscopically rough surface to scatter light evenly. This allows your device to measure light accurately, even from different directions, thanks to the cosine corrector functionality. Developed by Swiss experts, it ensures professional results every time.

Great little device!

These diffusers are great. It has been a chore for me to make little paper diffusers and tape them to my phone. This little device solves the problem and eliminates all the hassle.

Absolute must

As a beginner this was one device that helped me tremendously with lighting. My plants stop burning or reaching. Through the stages I was able to adjust perfectly.

3rd party app needed for meter to work

3rd party app needed for meter is free but you have to pay a monthly fee to get certain spectrums of light LED, HPS, ext. also been trying to get the app to recognize the diffuser for over 10 mins and I don’t think it’s working. Awesome deal in comparison to most PAR meters but not very intuitive setting up and having to pay a monthly fee not very impressed at all.

BuildASoil

We are adding more details about the APP on this product page so it's clear. The Photone app that I use, provided an option for a 1 time payment of around $5.00 to unlock the Full Spectrum LED tool and that's all I use without any monthly fee. I will confirm this today and post instructions here. Thank you very much for reviewing so we can be most transparent and also more helpful in suggesting the proper steps.
