TEMPERATURE: Cannabis is a very hardy plant and can survive cold and heat well. Just like you or me though, it can get stressed and not function well in the extremes. Cannabis can freeze or boil to death. It can stop growing or go into stasis. It will go into survival mode if the temperatures are too high or too cold for too long. Twenty-seven degrees centigrade is the accepted ideal for vigorous cannabis growth. Indoors this is easy to achieve with fans, air conditioning units, heating and cooling mats. Lights will certainly generate heat that needs to be vented.
LIGHTS FOR EVERY BUDGET: At the other end of the scale, you can have a rudimentary yet very efficient CFL (Compact Fluorescent Light) or small LED panel (Light Emitting Diode) setup for less than three hundred dollars. Growing great buds in a spare cupboard. Other compact fluorescent lights like T5 battens come in a range of spectrums for vegging and flowering and can fit in a small space well.
Step 2: Cannabis Fundamentals
GROWING MEDIUM: Organic growers will use some kinds of soil every time inside or out. However, soil isn’t the only choice. Neutral mediums that are entirely nutrient dependant include coconut coir, perlite, vermiculite or rock wool. Aeroponics, purely hydroponic or deep water culture do not use mediums at all. The suspended root matrix gets nutrients directly from the nutrient mix.
Cupboard, grow tent or dedicated grow room. Directly in the soil or in pots outdoors. Even in a companion planted garden your marijuana will need to satisfy all these needs to grow well and supply you with high-quality resin soaked nuggets.
WATER: Like all living things cannabis needs water to grow, thrive and carry out its biological functions. If you live somewhere with regular rainfall your outdoor crop may get all it needs from nature alone. Large cannabis plants are notoriously thirsty. If you are going big then you will certainly need to supplement water between rains.
These are round on bottom instead of being a cube, which means they cannot stand up on their own. These are best suited to a hydroponic setup where the Rapid Rooter will be placed directly in the final destination. In our hydroponic setups, we’ve had near 100% germination rates with Rapid Rooters, better than any other seedling cube we’ve tried.
Marijuana seeds need the following to get the best germination rates:
Germination Method 2: Plant marijuana seeds directly in growing medium
Pros of Rockwool
For fastest growth rates, it’s better to plant young seedlings or clones in a very small container, like a disposable plastic solo cup.
Keep CFLs or fluorescent lights about 6 inches away from your seedlings. Place your hand where the leaves are to make sure it doesn’t feel too hot. If it’s hot for your after 10 seconds, it’s too hot for your plants.
