Cannabis 101 – Indoor

*THIS PAGE IS UNDER CONSTRUCTION. FOR FURTHER IMMEDIATE HELP PLEASE CONTACT US FOR A CONSULTATION. CHECK BACK FOR CONTINUED UPDATES*

Indoor can be a fickle mistress. There are many things to understand before you just get a cannabis plant and place it inside your home. You must understand all variables thoroughly in order for your plants to thrive and produce anything of quality. You can grow any plant in substandard conditions but you will only get out of it what you put in with your limiting factor affecting everything from quality, vitality, and yield. Limiting factors are anything the plant needs that is limited in some way by the grower, nature or the environment the plant is in. You should try and take into account all limiting factors while constructing your grow indoors so you can maximize growth. A general goal though is that you are trying to replicate outdoor conditions, indoors; while limiting harmful factors. We will try to cover all common limiting factors and add to our list as we learn and grow with you.

#1 Photoperiod/Lighting

All plants will not grow properly without the proper lights and photoperiod. While some may stay alive in poor conditions, proper lighting will help a plant thrive. There are a few types of bulbs we recommend while growing indoors these bulbs are can be manufactured for different spectrums of light and with different materials also. Indoors we notice that the more different light you have on a plant the better it responds so one type is not necessarily the best; think of the sun there is more than one spectrum of light coming from the sun, there are alpha and beta wave radiations, UV’s, light spectrums that we cannot reproduce  (minus a nuclear reaction) on earth that are coming from the sun.

CFL’s

A cheap lighting source that can work well for cloning, mothers, and vegging. Provides one spectrum of light and some heat. This light has little penetrative effect on canopy growth and will generally only grow plant areas it is directly hitting. Great for side lighting you have to be careful of the heat it generates as it can burn plants as they reach towards bulbs. While they burn plants from the heat they generate they also don’t “throw” light as well as the other bulbs and need to be placed close to the plants for optimal results. A fan blowing between the light and plant is recommended.

HID lighting 

There are 2 main types of HID (High-Intensity Discharge) bulbs. MH (Metal Halide) and HPS (High-Pressure Sodium). MH provides a wider daylight spectrum of light. While HPS provides an orangish spectrum that is designed to improve the flowering cycle by attempting to target the wavelengths of light a plant absorbs. This light generates a lot of heat and ‘throws’ light a decent distance. The heat the light creates can be dangerous to plant growth unless growing in a colder environment and usually needs to be vented away. This has been industry standard to growing decently sized dense buds but can create environment issues. The standard sizes are 400W, 600W and 1000W. LED technology has recently advanced to begin a LED vs HID debate.

LED lighting

Has slowly become more accepted as technology has advanced recently. There are still reports of poor manufacturers and limited life of products. Generally LED has less yield than what they compare to as HPS bulbs unless you get an expensive COB full spectrum LED light. While you get less yield the fact the light runs cooler and you can place it closer to the plant is supposed to help the plant produce a better resin profile.

Plasma lighting

New to the market, even we admit we don’t know much about this thing.

What do we use?

We believe a combination of HPS and MH HID lighting helps us come as close to possible to the sun’s spectrum and produces the results we are after so we try and use a combination in our lighting pattern.

Vegetative growth

Requires 16-24 hours of light. Some strains can go as low as 16 hours to remain in vegetative state.

Flowering trigger/growing

Generally triggers at 12 hours of light and 12 hours of complete darkness.
