Lighting
How much light?
Having too much light for your grow space can severely inhibit yields and quality. Many growers seem tempted to push the wattage in an attempt to get a higher yield from their grow space however these attempts are repeatedly proven to be a waste of time and money.
Too many lumens cause problems.
There are a few reasons to use the ideal 'lumens per square foot' for your room:
- Increased Yield
- Increased Potency
- Increased Essential Oils
- Less Equipment Cost
- Less Electricity Cost
Simply put, too much light stunts growth and makes plants generally unhappy.
How many watts of light to use is quite easy to determine using Cannaversity's Grow Room Light Calculator. This will give you the ideal 'watts per square foot' to figure out how much wattage is needed for the dimensions of your room.
Determining the ideal 'lumens per square foot' (aka Foot-Candles) can be trickier. Look at this post on THCTalk about Ideal Lighting Charts.
How to place my light?
Each reflective hood generates a projection of light underneath it that creates a very specifically shaped light 'footprint' in which the 'lumens per square inch' are maximized for that ballast/hood arrangement.
Hydroponic Systems
Cannaversity has a great pictorial of the Various Hydroponic Types
Deep Water Culture (DWC)
Here is an example from Cannaversity of a Deep Water Culture (DWC) system with a Screen of Green (SCROG) built in.
