The definition of what’s thought-about another crop for greenhouse manufacturing will seemingly differ relying on who you ask. After all, just about each plant grown in a greenhouse most likely began out as a distinct segment providing, till a wider viewers discovered its potential.

This additionally implies that what is likely to be thought-about another crop immediately may simply develop into the following massive factor that each grower views as their assured ticket to a brand new market. Greenhouse-grown hemp and leafy greens are simply two crops which may fall into this class.

Here is a more in-depth take a look at some picks that is likely to be thought-about another crop, and the danger/reward components that may enable you to resolve whether or not they’re value pursuing.


The market demand for gourmand and medicinal mushrooms is growing considerably, in accordance to Barry Pryor, a Professor within the School of Plant Sciences at the University of Arizona.

“The risks of production are not great if facilities are set up properly, and there are several comprehensive production guides available online,” Pryor says. “Getting markets established is probably the biggest challenge.”

Another benefit is that some oyster and shiitake varieties can yield extremely excessive returns per sq. foot. And if you will get related to a farmers’ market in your space, you’ll be able to generate fast gross sales.

These excessive returns, nonetheless, additionally make it a danger, says Paul Brentlinger of CropKing Inc., which sells packages that embrace all the required buildings and tools for mushroom manufacturing.

“There is a decent amount of production moving into mushrooms, even though consumption is not increasing at the same rate,” Brentlinger says.

Stacy Tollefson, a Professor within the Controlled Environment Agriculture Center on the University of Arizona, additionally notes that whereas gourmand mushrooms generally is a moneymaker, growers want tight manufacturing controls, in addition to an autoclave (which generally is a substantial funding) to sterilize rising media.


On a basic degree, the manufacturing of strawberries and different berry crops will surely not be thought-about various. However, whereas most worldwide berry manufacturing is completed beneath some kind of cowl, right here within the U.S., aside from the most important growers reminiscent of Driscoll’s, there should not loads of berries being grown in a managed setting.

Variety choice is extraordinarily vital. Growers have to know essentially the most ideally suited cultural methods that can lead to high quality fruit manufacturing, particularly a crop that can final on retailer cabinets.

“The costs involved in all of this make it difficult to get high margins,” Brentlinger says.


The ever-growing craft beer craze has made hops a preferred crop selection. The benefit of greenhouse-grown hops, Brentlinger says, is that it offers growers a greater alternative to present moist hops (that means it may be delivered to a brewer inside 24 hours of harvest), which is a giant deal for breweries.

Brentlinger cautions that hops sometimes want to be hand-harvested, as the event of automation technology is lagging.

“Hops are easy to grow, but there is a ton of labor involved,” Brentlinger says. “Like any crop, maintaining cultural practices is a big deal, and the labor involved is the question mark as to whether hops can be profitable.”

Tollefson notes it may be tough to get excessive yields of hops, and the crop additionally may be very arduous to handle by way of pests.

“We still need to work on growing the right hops cultivars and setting the most ideal environmental parameters,” Tollefson says.


Crop specialists at Rimol Greenhouses say that ginseng, when marketed as a therapeutic herb and tonic, has a lot revenue potential that it has been dubbed “green gold.” For growers who’ve a small vacant plot and loads of persistence, this plant can reap big rewards.

Why persistence? Because rising ginseng can take up to six years, which is how lengthy it takes for the roots to totally mature to allow them to be harvested for consumption.

“If that is well beyond your timeframe, you can also sell young rootlets to other growers to bring some return on investment within a manageable timeframe,” in accordance to a weblog posted by the Rimol rising group earlier this yr.

“Over the six-year period, growers can make as much as $100,000 on a half-acre plot from seeds, rootlets, and mature roots,” the weblog says. “With ginseng, early birds most definitely do not get the worm.”

Vanilla as a greenhouse crop is unquestionably nonetheless in its infancy. Aside from a scarcity of viable analysis within the U.S., Tollefson says that vanilla is a labor-intensive crop as a result of it should be hand-pollinated.

On the plus aspect, the Wageningen University Research Program within the Netherlands has just lately enhanced its vanilla flower analysis. Tycho Vermeulen of Wageningen University says a greenhouse arrange for vanilla manufacturing wants a sustainable heating supply and an overhead irrigation system.

“The advantage of growing vanilla in a greenhouse is that you’re more likely to get a uniform crop,” Vermeulen says.

Filip van Noort, one other researcher with Wageningen, says the shortage of excellent plant materials and an general lack of awareness stay obstacles.

“However, if you’re a grower who has time to learn, money to invest, and a market to buy it, you’re off to a good start,” van Noort says.

Specialty Greens

Leafy greens, as an entire, is one other crop that may not be thought-about various. However, the extra specialised you might be, the extra seemingly you will discover a distinct segment market.

“Many of these growers are producing a crop on less than half an acre,” Brentlinger says. “For many of them, it’s easy to diversify your crop selection and stick out from other growers.”

Chaz Shelton of Merchant Gardens in Tucson, AZ, says the training curve for specialty greens is low, and you’ll often get a fast crop turnover.

“The risk is the potential for massive competition, as most early entrants into indoor hydroponics start with leafy greens, which can lead to market oversupply.”
