Welcome to Hahn’s Lighting and Hydroponics. We are San Jose’s premier hydroponics retailer. Other stores will come and go, but we’ve been supporting south bay growers for over 20 years. We have long standing relationships with our suppliers and customers that allow us to bring them together to achieve a common goal. That goal is the growth of large, healthy, and tasty fruits, vegetables, and herbs for you, your friends, and family. Unlike other stores, we will be here to support your purchases for the foreseeable future. We are in it for the long run, and for that reason we sell brand name, top quality equipment like Hydrofarm, General Hydroponics, Advanced Nutrients, Air King, Phat Filter and Fox Farms just to name a few. Nothing less will do.
If you’re looking for our location just look over at the contact page for a map link, address, and phone numbers. Also there is a form to drop us a note, ask a question, or for general feedback.

Better than plastic containers – Hard-sided plastic containers are relatively inexpensive but they are not a very good home for a plant’s root structure. Plastic allows no aeration, conducts and holds heat, and provides inadequate or poor drainage. Even on mildly sunny days, container soil temperatures can easily top 120 degrees, damaging or killing the roots and stressing the plant. The #1 killer of potted or container grown plants is over watering and plastic containers with a few bottom drainage holes actually help the soil stay too wet. A Smart Pot is constructed of a porous fabric that allows heat to dissipate and excess water to evaporate. In fact, over-watering is never a problem because excess water drains and evaporates from all of the Smart Pot’s surfaces; its walls as well as its bottom.
Because the Smart Pot is a fabric container, giving the root ball total aeration and excellent drainage, you can even use a heavier, less expensive planting mix. The type of mix used in a Smart Pot is less critical then in hard-sided pots. Also, another Smart Pot benefit is root pruning, a technique used by many commercial nurseries to produce masses of highly branched roots to improve plant quality. When a root grows to the side of the Smart Pot, it stops growing in length and develops many, many fine branches. By contrast, the roots in a plastic pot continue to grow in length when they reach the side and circle around the side of the pot. This is undesirable as there are fewer roots and these can grow around each other causing girdling or strangulation. A branched, fibrous root structure (“root pruned”) has a far greater root mass than a comparable plant where the roots are circling on the inside of a plastic pot. And a greater root mass will grow a better plant.
Today, Friday March 20th is officially the first day of spring. Although the weather this weekend isn’t going to be the best for gardening, and we wouldn’t suggest putting anything out just yet as we’re not past the last freeze, we do suggest thinking about getting your seeds started inside where they are protected from the elements.
Here at Hahn’s we have everything you need to get a jump start on your growing season. We have trays, domes, seedling heating mats, rooting medium, cloning gels and more. I’m starting my seeds, maybe you should too?
Hydro Garden Armor is a tray liner that can make your life easier. As any hydrogrower can tell you clean up can be a pain in the neck. With these liners it couldn’t be easier. Just drain the water and throw it away!!! Leaving your tray or reservoir nice and clean. So if make that next cleaning the last or keep that new tray or reservoir looking brand new and line it with Hydro Garden Armor’s tray and reservoir liners. They make a 60-70 gal liners @ $12.95 and 100-115 gal reservoir liners @ $14.95 and 4×4 @ $12.95 and 4×8 tray liners @ $14.95.
We’ve hooked up with hydroponics dictinary to bring you some very useful tools for your garden. You can check it out by going to the tool page. All you have to do is click on the tools link on the tool bar above or just follow this <link>.
It is with great sadness that we need to pass on news of the passing of Ian Holly a long time colleague, guiding force, and all around great guy. Ian was a key figure in how and why Hahn’s Lighting is what it is today. Ian helped countless gardeners find success in their endeavors. We still hear stories of how Ian got them started all those years ago. Ian will be greatly missed but never forgotten. Ian’s family suggest that if you feel compelled to do so please donate to your favorite charity in Ian’s name.
No, that’s not a typo.. We have ONE unit at that price. That’s 1 600w bulb, 1 600w sun system ballast, sun system cord set, and sun system super sun hood. That’s a killer deal on a good system. The only problem is we only have ONE at this price. 327.00 + tax

As you can see it’s a little different then your basic grow tent. This only lasted about 24 hours in the shop before someone bought it..
New and improved with heavy duty zippers and double stitching – 100% light-proof!
The hottest product of the year just got a whole lot brighter. Introducing the Dark Room – the most advanced grow tent available. Here are just some of the unique and exciting features you won’t find elsewhere:
* Highly reflective interior – significant increase in reflectivity for improved lighting performance
* Thermally protected – tent material reflects 97% of all radiant heat for superior insulation
* Completely non-toxic – will not react under light and heat, and no off-gassing to harm plants
* 100% light-proof material – prevent light from escaping or entering for controlled light cycles
* Moveable roof cross-members – easily adjust lighting and accessories
* Multiple intake/exhaust ports – including two ports opposite each other at reflector level for air-cooling of lighting system
* Fast, easy assembly and disassembly – includes carrying bag for portability
* Adjustable fan and filter attachments – no more clamps or reducers needed!
* Solid construction – roof cross-members easily support 65 pounds
The Dark Room has all the features you could ask for – and more! Outfit the Dark Room with the ventilation fan, lighting system and growing system of your choice and you will have the brightest, slickest, most affordable grow room available.
The Dark Room is the first grow tent to utilize thermal film on the interior. This film is highly reflective, waterproof, and extremely insulative (offering 97% thermal protection). This film is also non-toxic and won’t release any harmful gasses that can damage sensitive plants.All of the zippers used in the tent are extremely durable and 100% lightproof.
The Dark Room frame is constructed of 0.70mm thick, 15.9mm diameter metal poles, making it very rugged for everyday use. The poles also utilize a special surface treatment that aids in installation and enhances their appearance. The poles that make up the ceiling framework are moveable, making it so much easier to adjust the positioning of lights, filters or anything else you may end up hanging from them. The ceiling poles have been improved to handle significantly more weight, especially at the center (where most other tents have a tendency to sag).
The new corner fittings are made from a virtually indestructible polymer that bends under extreme pressure instead of snapping. These fittings are much stronger than competing fittings (plastic or metal) and won’t rust like metal fittings. Their design also makes installation much easier than other tents, since the frame poles slide easily into the fittings with little or no resistance.
All Dark Room models ship with complete, full color, illustrated instructions and a heavy duty carrying bag.

Also, be sure to check out our video page. We have and will have lots of good youtube videos on important topics in hydroponic and soil gardening. Let us know if you have link to an video that you think is worthy and will add it on.
Well apparently it’s the Indian Bhut Jolokia also known as The Ghost Chili.. Wooo scary.. no really listen to this.
“It is so hot you can’t even imagine,” said the farmer, Digonta Saikia, working in his fields in the midday sun, his face nearly invisible behind an enormous straw hat. “When you eat it, it’s like dying.”
I’ll pass.. this pepper has more then 1,000,000 Scoville units.. I don’t even know why anyone would want that..
