How PGRs Make You Money
How do you know when it is cost-effective to use plant growth regulators (PGRs)? Certainly they can be used to regulate plant growth and size, but that is just one part of the equation. Chemical costs are the primary concern to growers. There is certainly a variable cost associated with using plant growth regulators. The growth controlled with PGRs allows for tighter plant spacing. Thus, there is less square foot per week cost, and a lower fixed cost assigned to the pot. So, we need to evaluate if the fixed cost savings is greater than the variable cost of the PGR application. To provide an example, let’s use geraniums grown in a 4-inch square pot. This geranium crop will be grown for 10 weeks. For four weeks, plants will be placed pot tight at 4 inches by 4 inches. For the final six weeks, the plants will be spaced at […]

Preventing Plug Stunting
We have all heard the cliché doctors make the worst patients. Well, sometimes greenhouse growers make the worst horticulturists. We have learned over the years just how far we can push our plants. A case in point is plugs. They often arrive in large batches, usually when there are not enough folks to transplant them or, more likely, when there is not enough space to put finished plants. Of course, when the season is busy, more plug shipments arrive before we have a chance to finish potting the previous ones. The result: Plugs sit on the bench for days or weeks, continuing to grow. They can become quite leggy, sometimes nutrient deficient or, in worse cases, die. But we still need the finished plants. So we pot them eventually and often, they never produce a quality plant. So can anything be done to produce high-quality plants from these plugs? We […]

Using The Plant Growth Regulator Calculator
Rounding out the GroCALC software package, PGRCALC is the third and final program that has been updated in the past few months. The calculator has been updated from a Microsoft Excel-based program to a Web-based application that does not require a user download. If you are currently using PGRCALC, you know how this tool can give you confidence in your PGR applications. If you are not familiar with PGRCALC, you will soon realize how easy and quick it is to calculate the amounts of a PGR and water you need to mix for any application. PGRCALC will calculate the amount of an individual PGR product to add to a volume of water to obtain a desired concentration. In addition, it will also calculate the cost of the total application and cost per pot. Getting Started To use the new version of PGRCALC, point your Internet browser to www.nhfloriculture.com. You will […]

Using The Alkalinity Calculator
If you have tried to use the Greenhouse Media Lab Acid Addition Calculator, the alkalinity calculator from Purdue University and North Carolina State University in the last couple years, you may be disappointed that it no longer worked. The problem lies in the fact that when Microsoft updated Excel, the alkalinity calculator was no longer compatible with the program’s latest version. Fortunately, a solution was developed with the support of the Fred C. Gloeckner Foundation. If you’ve never used the alkalinity calculator, then welcome to the redesigned alkalinity calculator, AlkCALC. AlkCALC is an application that easily calculates the amount of nitric, phosphoric or sulfuric acid required to neutralize alkalinity in your irrigation water to a desired level. In addition, it will determine the amount of nutrients added by acid injection and the cost of your specific acid injection needs. Getting Started Unlike previous alkalinity calculators, AlkCALC does not need to […]
