Air Cooled Growlights
Summer can provide a genuine difficulty for indoor gardeners. When things warm up outdoors it can trigger temperature levels to rise in your indoor garden unless you are appropriately prepared. High temperatures brings with them an entire host of problems. Your plants enter into “survive-mode” instead of “thrive-mode.” That means that they stop concentrating on development and bloom and rather turn all their energies to “surviving it”– whether you are growing fruit, veggies or natural herbs the outcome is the same: lower yields and lower quality. Downer!
There’s also an enhanced threat of parasites in hot (and dry) environments, and woe betide you if you permit your nutrition solution to end up being too warm– you might also provide a personal invite for Miss Pythium to pay all your plants a visit! It’s not a surprise then that lots of growers choose to shut down for a couple of months and turn their focus on outdoor crops, however it’s still completely possible to keep your indoor garden going 365 days a year without any interruptions, no matter what environment you live in.
The obvious heat-beating technique is to set up an air-conditioning system. However this simply isn’t really possible or practical for everybody. Other growers make use of air-cooled lighting to handle increasing temperatures in their indoor gardens. After all, it’s your HID bulbs that produce the vast bulk of heat– so it makes good sense to take on the trouble at source.Air-cooled lighting is not a complex idea The bulb is encased behind glass in a tube or reflector. Both designs have 2 holes at either side, one for air to be blown in and one for air to exit, taking heat with it. So, utilizing an extractor and a couple of lengths of ducting, it’s rather simple to produce a stream of cool air, blown straight over the bulb, which constantly cools it. The hot air leaving the reflector is then ducted from your indoor garden, decreasing its capacity to warm up your growing environment.
Suck or Blow? For best outcomes, the cool air needs to be blown over the bulb, not drawn over it. There’s still a great deal of discussion in the indoor gardening community over this one– however one excellent reason is this: it’s much better for the fan to blow cooler air with it, instead of “suck “hot air directly into it from around the light. You can likewise line up 2 or 3 air-cooled lights in series making use of one fan and ducting between lights– this strategy is popular with growers making use of bigger fans and reducers. It also produces a lot less ducting and fan chaos! The cooler the air you can pass over your HID bulbs, the more heat it has the ability to remove.
A properly air cooled light can get rid of approximately 50 % of the heat of the light. Some growers even go to the extent of passing air-conditioner-cooled air over their lights(and not air-conditioning their indoor garden itself!). Nevertheless, air-cooled lighting isn’t really simply something that’s good to have in the summertime– it permits you to place your lights closer to yourplants throughout the year, indicating they can enjoy a higher light intensity. And more light on your plants=more yield. It’s as basic as that. Air-cooled lighting likewise decreases the expense of running a huge air-conditioner. A cooler bulb lead to less bulb stress and failures. It is a lot easier to eliminate heat at the source as opposed to attempt to get it after it has gotten in the indoor garden.
Due to the little volume of air in the reflector(compared to the whole volume of the indoor garden), much less energy and effort is needed to get rid of the same quantity of heat. As pointed out earlier, there are 2 sorts of air-cooled lights readily available: reflectors and tubes. Cool-tubes permit the grower to extract heat from the bulb entirely without needing to handle the resistance of a bigger, possibly more troublesome reflector. Nevertheless, the spread of light from a cool tube is smaller sized.
Rectangle-shaped air-cooled reflectors normally feature a flip open glass cover underneath the light. Some very early air-cooled reflectors utilized poor quality glass. Huge error! The lower the quality glass, the more it soaks up light– light that your plants can be making use of. See to it your air-cooled rig makes use of premium glass. However much more significantly KEEP IT CLEAN! Unclean, dirty glass can take in more than 15 % of the light from your lamps instead of it reaching your plants. Likewise bear in mind: glass soaks up UV which can assist with the manufacturing of crucial oils in some crops(e.g. basil, mint and rosemary. When ducting air from your air-cooled lights, make certain you utilize insulated ducting inside your indoor garden. This will assist to prevent heat leaving through the ducting itself and thus enhance the effectiveness of your cooling. Lastly, examine exactly how well sealed your air-cooled reflector is.
A simple means to validate this is to turn on the fans that are cooling your reflector(and nothing else fans in the room)and light a match beneath it. Blow it out and view the smoke. Does it get sucked up to the reflector? Bad seal! Good seals are particularly essential when you’re including extra CO2 to your indoor garden as you do not want it to be extracted through your lights before your plants have benefited, good seals are especially vital. Other bits and bobs you might require:
- Insulated ducting to match reflector and fan – 4″, 6″, 8″
- Duct clamps – 4″, 6″, 8″
- Inline fan
- Timer for fan (or fan could be plugged into the same timer used for light)
