Growing Peppers Vertically – “Poor Man’s Hydroponics vs Large Commercial Hydroponics

Q.  Can I grow peppers vertically – like I do my tomatoes?  How do you do it?
 
A.  Some information from the University of Florida Extension division at https://edis.ifas.ufl.edu/HS228 is fascinating – if you are interested in doing “The Poor Man’s Hydroponic Method” of growing peppers vertically.  Pictures of the two common commercial growing methods – the Dutch V and Spanish methods are posted at https://photos.groups.yahoo.com/group/MittleiderMethodGardening/lst.  Key paragraphs from the article are duplicated at the bottom of this article.
 
The Dutch V method prunes the plant to two main branches, and then guides those up strings in a V shape.  Little pruning is done in the Spanish system of growing.  Pruning to two or four main branches is common practice, and thereafter no pruning is done.  Vertical support is provided by poles and strings, or by large tomato cages. 
 
When a pepper plant is carrying the maximum weight of peppers the plant can support, it will stop flowering and fruiting even though there may be weeks or even months left in the growing season.  Removing green fruits as soon as they mature signals the plant to continue flowering and setting fruit, and the result is fruit being set throughout the growing season, and obviously more fruit per plant.
 

“Greenhouse pepper cultivars generally have an indeterminate pattern of growth. Because the plants can grow up to 6-ft tall during a growing season of 250 days, they need to be supported vertically. Pepper plants can be trellised to the Dutch “V” system or to the “Spanish” system ( Fig. 8 ).

“Trellising plants with the “V” system consists of forming a plant with two main stems by removing one of the two shoots developed on each node and leaving one or more adjacent leaves per node. The pairs of stems are kept vertically by the use of hanging twines that are wound around the stems as they grow. The “V” trellis system is used by Dutch and Canadian growers.

“Some of the commonly used cultivars are Parker, Triple 4, Cubico, and Lorca for red; Kelvin, for yellow; and Neibla, and Emily, for orange fruits. New pepper cultivars for greenhouse production are introduced every year by seed companies

“When comparing cultivars for those with the highest yield and fruit quality characteristics with low amounts of culls or other disorders, the best red cultivars were Lorca, Torkal, Triple 4, and Zambra; yellow cultivars were Pekin, Kelvin, Neibla, Bossanova, and Taranto; and orange cultivars were Paramo, Lion, and Boogie
 
“Greenhouse pepper crops in Florida are grown in soil-less culture. Thus methyl bromide is not needed, yet problems with soil borne diseases, and insect and nematode pests are avoided. The plants are grown in containers filled with soil-less media such as perlite, pine bark, or peat mixes. The media can be reused for several crops (two to three) if disease contamination does not occur
 
“Pepper plants in soil-less culture are fertigated (watered and fed) frequently with a complete nutrient solution. Nutrient solution concentrations are similar to those used for tomatoes grown in soil-less culture. In plants at full production, the nutrient concentration levels can reach N: 160, P: 50, K: 200, Ca: 190, Mg: 48, and S: 65 ppm, respectively. The irrigation solution also provides the plants with micronutrients.
 
“The pH of the irrigation solution is maintained at values between 5.5 and 6.5, and the EC, depending on the nutrients concentration levels, will have values between 1.5 and 2.5 mS per cm.”

Growing Commercially – Mittleider VS Hydroponics

Q.  We want to go into gardening commercially, and hydroponic greenhouse growing has been recommended.  How is your Method similar or better for us than going hydroponic?

A.  Before you spend any money on Hydroponic buildings and equipment you need to learn about the Mittleider Method, for sure! Building a Mittleider-style greenhouse will save you many thousands of dollars in the building of it and many thousands more in operating costs.  The Mittleider Method is sometimes referred to as modified hydroponics, because we feed the plants the 13 necessary nutrients, in a scientifically balanced ratio.  However, rather than putting expensive instantly water-soluble formulas in the water supply, we use Natural Mineral Nutrients that are easily and inexpensively obtained and apply the nutrients right on the soil – then water them in.  Also, as alluded to in the previous paragraph, unlike hydroponics, we grow plants right in the ground, or if we’re in Greenhouses we use raised Grow-Boxes with open bottoms, so the plants still have access to the natural soil – to obtain other nutrients they may want or need.  Mittleider gardens are well known for producing tremendous yields, even approaching those of hydroponics, while our crops like tomatoes are better tasting and cost a small fraction of those grown by hydroponic methods.
