To improve the resolution of the overall picture , more exacting data can be added . Simply adding how many of which variety was grown can help . This allows for an average to be taken by adding up the total harvest for each variety and dividing by the number of each variety . Then the varieties can be compared against each other to determine which produced more . If two Purple Lady plants produced a total of 170 grams ( g ), then they averaged 85 g apiece ( 170 g / two plants = 85 g ). This information can be used the following planting season when selecting how many seeds to plant . If the goal is to have half a kilogram of smoke at harvest , and your garden tends to produce 70 g per plant , then that would be about four plants taken to harvest . If the average is a 160 g yield per plant , then two to three plants should cover it . While production numbers should still be mitigated with other factors such as quality , it can be useful when making judgment calls . A middle-producing variety with okay smoke should generally lose space to a high-producing great smoke . If the numbers show a high-quality variety doesn ’ t produce well , then an informed decision can be made . A commercial grower may decide to only grow that variety for their own use , or to charge more to make up the difference if the market will bear it , or they may not grow that variety at all anymore in favor of better producing strains . Outdoor gardens that only produce a single harvest a year can be calculated by the year , but with light deprivation or indoor growing , seasons are a bit more arbitrary and at the whim of the grower . Indoor growing seasons may be as short as nine to 10 weeks or extend to several months depending on how long the plants are kept in growth , and how long the variety requires to flower .
Calculating Grams Per Day
To account for these differences in growing seasons , a time factor can be included into the calculations . Grams per day ( GPD ) allows for plants of different growing periods to be compared . Take the planting date and subtract the harvest date to find the number of days between . If plants were started on May 23 , 2018 , and harvested on Sept . 29 , the season would be 130 days . If the Purple Lady example were used , then its average weight of 85 g per plant could be divided by the 130 days it took to grow them , to show a GPD of 0.653 ( 85 g / 130 days = 0.653 ). If it instead didn ’ t ripen until October 5 , then the 85 g would have taken 146 days . That would give a value of 0.582 GPD ( 85 g / 146 days = 0.582 ). The GPD for the whole garden or each individual plant can be calculated and compared . Individual plants with high production rates are often particularly good candidates for breeding . Although production should not be the only factor in selecting parent plants — as long as there is not a reduction in quality — quantity is often considered a desirable trait .
