The HGR Promise
At HGR Garden Supply, we are dedicated to serving you, the grower. Helping you become a successful grower is what we are all about – if you aren’t succeeding, then we haven’t helped you reach those standards. We are constantly thinking of ways to innovate and to set us apart from the other garden stores. We offer many free services to help you achieve success. Our team has over 50 years of combined experience in the garden and nursery business – let us help you become a master gardener!
We repair magnetic ballasts and T5 fixtures for a fraction of the price of buying new! Do you have a ballast that stopped working? Chances are it’s a simple capacitor or ignitor – both problems that we can easily solve for you! If you buy the replacement parts through us, we will install them for free!
Free Grow Classes
We frequently hold informative and interactive grow classes in the store. Can’t make it in? Don’t worry, our classes are video recorded and posted in our forum section under “HGR Videos”! Our classes cover a wide variety of topics, including full nutrient breakdowns, pest and disease management and much, much more! Whether you are a beginner or a plant expert, you WILL learn something new! Our classes are always accompanied with free food, drinks and sample nutrients for you to take home!
Having a problem in the grow room? We can help! Chances are, we’ve had the same problem ourselves or we’ve heard the same story from someone else. If you are having problems with pests, nutrient deficiencies, toxicities, lockouts, room temperature, humidity or anything else, we have simple solutions for you to get your garden back on track! Give us a call anytime during business hours and we’ll be more than happy to help you resolve your problems! We are open Monday-Friday from 10am-7pm EST, Saturday from 10am-6pm EST and Sunday from 10am-5pm EST. We can be reached at 1-248-369-8333.
Grow Room Design
Building a new room? Are you having second thoughts of what the layout should be to achieve optimal results? We have designed hundreds of successful grow rooms over the years, and we love doing it! We know all of the tricks for keeping room temperatures in check, preventing pests and diseases and maximizing your lighting situation. We’ll educate you on how to eliminate problems before they occur, not after!
Looking to upgrade your equipment? Do you have some old equipment you aren’t using anymore? Are you just starting off and need to save a few bucks to get your garden up and running? We sell just as much used equipment as we do new! Save money on those ballasts that you need and use that money towards that premium nutrient line that you have your eyes on. We buy, sell and trade used equipment! Head over to the “trade up” section on our website to see our current stock of used equipment!
HGR offers both our own mix of soil and will offer to make up your own special blend, too! Our soil is known as MOM’s Mix (Michigan’s Organic Mix) – which is an all-in-one ready-to-go soil for the growers who don’t want to worry about feeding and just water only. Want to make your own soil? Simply start with whatever base you want (pro-mix, sunshine, coco, roots organic), add any amendments you want to your liking (perlite, vermiculite, mycorrhizae), and finally add your supplements (blood/bone meal, guanos, worm castings, phosphates, etc.) We will put in the labor of love and turn the soil for you, and fill your containers for free!
Are you using C02 supplementation? HGR Garden Supply carries both steel and aluminum tanks; 20 lbs. and 50 lbs. Don’t worry about having to wait to refill, we simply swap out tanks so you can be on your way! Are you new to using C02? We’ll educate you how to properly install a system and how to regulate the flow.
Whether you have a pH pen, PPM/TDS/EC meter, c02 reader or lux/lumen meter, we can help you calibrate your equipment so you are running your room with accuracy! All meters need to be calibrated on a regular basis to ensure they are reading correctly – if you have trouble re-calibrating your equipment, bring it to us and we can do it for you!
There are a lot of products that grow stores sell that the customer is only going to use a few times a year. Why tie up your money into something that is going to sit in the corner and take up space 363 days out of the year? For this reason, we decided to rent certain equipment at a very affordable rate. Head over to our Rental section (under Products > Specials Offers > Rental) to see what we have to offer!
