How to choose a grow bulb

We get asked the question a lot, what kind of bulb is best? Strangely, it is never followed with, why? Knowing what makes a grow lamp a good light to use is a beneficial criteria to know.

Lumens - The amount of light emitted from the bulb

Par - The distribution of the light across a plan

Spectrum - The colors of the light reaching your pants.  MORE ON THIS HERE.

Mean Lumens - The average amount of light that the bulb will emit during its peak life

Peak Lumens - The highest amount of lumens the bulb gives off

Average Life - The amount of hours the lamp will typically burn for

Color shifts - Any bulbs denoting shift typically means that bulb is slightly varied from the standard colors.  Ex. An HPS can be shifted for even more red or added blues for wider spectral lengths.

Frequency - The

Wattage - The amount of energy used to power the light.

Bulb type - There are several different types of grow lamps these days.. Dual Arcs, conversion bulbs, HPS, MH, Mercury Vapor, Halogen, Incandescent…  and many have different base types and sizes.  Not all are interchangeable.

Base Type - Can be E-39, E-52 and several other types.  If you are unsure, check the box, and sometimes the bulb will have it printed on it.

Position - can be universal, horizontal or vertical.  Unversal can be denoted as vertizontal, a clever play on the words I think.

Enhanced Performance Carbon Filters by Gro1

Carbon filters are THE preferred way to eliminate odors from indoor gardens.  Choosing a filter is easy at Dr. Greenthumbs.  First you need to now the CFM level you are looking for.  A good rule of thumb is to have the CFM be 1/4 the size of the space you are trying to clean odor wise. If you have a 1000 cubic feet, a 200-250 cfm will be fine.  That means the air is scrubbed every 4-5 minutes.  For more serious cases (when the smell is overbearing) a 2:1 or 1:1 ratio may be needed but REMEMBER, the more air you move the more effects it can have on the rest of the set up.  If you are scrubbing the air out, you will get negative pressure.  If you are simply scrubbing the air in the room with no out vent, then reduction of the smell will occur but not to the same degree as one scrubbed out, but the smell will subside and become more bearable if not miniscule.

For best results scrubbing out, have the carbon filter raised as high as possible to capture as much hotter air and smell as possible.

For best results scrubbing the inside, of a room only, place the carbon filter as close to the plants as possible, again preferably near the ceiling.

NOTE:  Filters may be heavy depending on size.  Take extra care to hang them properly.
