Frequently asked questions

We sync stock status from our suppliers daily. If a product is listed as in stock, it is in stock at the supplier — but in rare cases stock can move between sync windows. If we ever cannot fulfill an in-stock order, we contact you immediately, refund instantly, and help you find an alternative.

Add what you want to your cart, click Checkout, enter your shipping and payment details, and confirm. You do not need to create an account — guest checkout works for everyone.

All major US credit and debit cards (Visa, Mastercard, American Express, Discover) via Stripe, plus PayPal. (Buy-now-pay-later options like Klarna and Affirm are deferred to a future phase.)

We process orders fast, often the same business day. If your order has not shipped yet, message us and we will modify or cancel it. Once it ships, treat it as a return.

The lower 48 states (the 48 contiguous states plus DC). We do not ship to Alaska, Hawaii, US territories, or internationally. Every order leaves a US warehouse and arrives at a US address.

It depends on the product and the supplier. Most orders ship within 1–3 business days and arrive within 3–7 business days after that. Larger items (AC, dehumidifiers, complete systems) may take longer. Your tracking email will give you a specific estimate.

Yes — shipping is calculated at checkout based on weight, destination, and supplier. We do not currently offer free shipping; what you see at checkout is what you pay, with no surprise add-ons later.

Often yes; sometimes no. We work with multiple US-based suppliers, and orders with items from different suppliers may arrive in separate packages, on different days. You will receive a tracking number for each package.

When your order ships, we send a tracking email with the carrier link and tracking number. If your order ships in multiple packages, you will receive a tracking email per package. If you need help locating it, message us with your order number and we will send the tracking detail directly.

Check your spam folder first. If it is not there, message us with your order number and we will send the tracking detail directly. We do not delete tracking emails after sending — they are always retrievable.

Carriers occasionally pause updates between scan points without it meaning anything is wrong. If a tracker has not moved for 5 business days, message us and we will investigate with the supplier and the carrier.

Painless 30-day returns. If something is not right, message us within 30 days of delivery and we will help. There are no restocking fees on standard returns.

Most items in original, unused condition with packaging are returnable. Sealed nutrient bottles, calibrated meters, and electrical items that have been wired and used are typically non-returnable for safety and resale reasons. We will tell you exactly what applies to your item when you reach out.

Message us with your order number and the reason. We will respond within 24 hours with return instructions and the address to ship to. Do not ship items back without contacting us first — different suppliers have different return addresses.

We process refunds within 2–3 business days of receiving the returned item. Your bank or card issuer typically takes another 3–10 business days to make the refund visible on your statement.

Message us immediately with photos of the damage and the packaging. Damaged-on-arrival items are handled separately from regular returns and we will sort it out fast — usually a replacement, sometimes a refund, depending on stock.

No. Premier Hydro is a US-based retailer that ships exclusively from US suppliers to US addresses. There are no customs declarations, no import duty, no VAT, no surprise fees at the door. The price you see at checkout includes shipping; what you pay is what you pay.

Many online sellers in this category — especially the discount marketplaces like AliExpress, Temu, and various grey-market sellers — ship from outside the US. When products cross the border, they generate customs declarations and duty fees that are typically billed to the buyer at the door, on top of what was paid at checkout. We do not do this because we do not ship internationally; everything in our catalog is already in the US.

No. Only to the lower 48 US states.

Yes. Send us a message with your tent size, what you are running (lights, fans, controllers), and what you are trying to add. A real grower will reply within 24 hours with a recommendation and the why behind it.

We pull specs from the manufacturer and the supplier. If you spot a discrepancy or a missing dimension, let us know — we want the catalog accurate and will update it.

Most products carry the manufacturer’s warranty. We help you with the warranty claim — you do not have to call the manufacturer yourself. Message us with your order number and a description of the issue.

Yes — for orders above a certain volume, we can offer better pricing and dedicated support. We are not a full wholesale operation, but we do support larger US-based growers and institutions. Tell us what you are trying to buy and we will quote it.
