Do green house farming is economically applicable in area like the Philippines?

Question

By the way, i live in laguna,phillipines, where theres is a lot of rain,sun and typhoons

?

Answer 1

Since typhoons are major considerations, then economically, greenhouse farming is not a good choice. A further consideration would be the crop that you would be growing. If it is a high value crop that requires a secure growing conditions, then relocating to a site that is not typhoon prone might be a better option.

Answer 2

One can green house anyplace and every place has it's own unique problems. Given that you have a crop that is greenhouse worthy, in your location you will need good air exchange, a low profile with a south facing roof that is a single angled cover supported by a high solid back wall (north wall) and a low clear or solid south wall. Low as possible lets the wind over, and solid walls support the high back against severe weather. The single roof slope sheds rain (to catch basins?). Roof should be fiberglass or polycarbonate 15 year plastic. Inflated hoop houses of polyethylene sheet will probably not make it threw a typhoon and glass would not either. But it depends on what your seasonal weather extremes are. Gabled greenhouses might not hold as well to heavy weather but if you have a real good steel frame well bolted, it might. You will need to white wash in the heat and dry season to minimize inside temperature, and then let it slowly wash itself off during the rain months. You need good air exchange when it is wet/ damp or you will have problems with fungus and I would guess that no matter where you are all your venting needs to be covered with insect mesh. It slows the movement of air a bit but it keeps the bad bugs out for the most part. You'll have to let me know what crop you plan on for any other details.

Answer 3

Greenhouse farming would not be an economically advisable alternative for the Philippines. If you were growing a very high value delicate product, like orchids or other delicate flowers it might be economical, but that is about the only way. If you have a typhoon you will likely loose your crop anyway and quite likely your investment in the greenhouse.

Answer 4

I live in Colima, México, same latittude than Filipinas, 500 meters above sea level. There are many new green house farms now, growing mainly tomatoes, before, planting tomatoes in ground would yield 40 metric tons per hectarea, now, in green houses, they produce up to 800 tons per hectarea, better quality fruit, and the price in market became uniform, same price all year long. there are many other products, many.   [e-mail]

Answer 5

It does not seem likely that greenhouses would be necessary in a tropical region.  Greenhouses raise the temperature and humidity in a controlled way, as well as helping to regulate the amount of sunlight.  In Philippines, that would not be necessary, at least not with a traditional greenhouse (glass/clear plastic).

A traditional greenhouse would probably get destroyed in a typhoon.

Answer 6

I believe so.  Controls pest easier and protect from excessive rain.  Good for organics.  I wouldn't do it though because open farming is cheaper.  I use to live in Batangas and we have farms.  In Calabarzon everything grows that you hardly need a greenhouse unless you have some exotics you want to protect or just doing it for hobby.
