Java Script must be enabled
- Select a High Pressure Sodium lamp (scenarios are for single lamp gardens)
- Select a light intensity (determines canopy space)
- Select a level of growing experience (use the default if you've never grown or researched indoor cultivation)
- If you don't use hydroponic media change the default to non-hydro medium
- Optionally change defaults for your target production settings
- Click any ReCalc button to refresh the totals (a custom report is generated each time)
Tips for finding a niche that fits your schedule & life style
Growing Scenario - A growing scenario that produces more crop yield has a powerful global affect on your workload, and is by far the best way to reduce both the number of crops grown and the number of days it takes to meet your target. If minimizing your workload and time in the grow room is important to you, don't scrimp on the crop yield produced by your growing scenario.
Veg Time - Veg time will not affect the number of crops needed to meet your target, but will affect the total number of days each crop needs to be grown. Given the same strain maturity time, longer veg times usually require fewer plants.
Safety Margin - This will affect both the number of crops and days spent growing. The effect is the percentage difference in the change you make. For example, changing from 15% to 0% will reduce your Target Production by 15%. However, keep in mind that with no safety margin you may have no surplus to draw from in the event of a poorly producing crop.
Crops Grown - The number of crops needed to meet your Annual Target Production. Each crop requires the same duties and chores to be repeated by the grower, such as media replacement, plant replacements, reservoir changes and between-crop clean up. Costs would be repeated as well. A higher number implies a degree of extra work, time and expense not reflected in the days spent growing crops. Those interested in minimizing their workload and time in the grow room would want to seriously consider the number of repeat crops as well as the days spent growing them.
