Growing outdoors plants in thailand for extraction purposes
Hi! I have been growing all season in the north of thailand nearby chiang mai. Since I have some nice seeds left im gonna start the grow end may. This is around the start of rainseason (between 150- 290mm rain p month) in thailand. The plants will be used for extraction purposes so we are aiming for a high bio mass total not super nice top buds.
Conditions are:
- Clay/ soil ground, acces to filtered mountain water, organic fertilizer
We are expecting a lot of rain and will work with raised bed system so that excess water can drain away. Also covering the plants with see-through terp or nets to minimize the water exposure.
Anyone have tips or suggestions on dealing with a lot of rain and full soil?

Strain selection is key. Sativa dominant varieties would tend to have longer, thinner buds, which should make them less likely to mold because they get better air circulation.

use some agricultural lime on the soil. it will break up
clay over time. do not use dolomite lime it binds the clay
together. compost dug in will help. then some kind of soil
spacer. perlite small river, rock ect. mixed in so soil drains.
best of luck.

Thanks for the advice, it makes sense and didn’t think of this before.
We were planning on mixing our clay 50/50 with good soil and indeed putting gravel stone down the hole for draining.
Would you say to mix the agricultural lime together with our 50/50 clay soil mix? Or add some on top only?

Good point! I am putting 7 strains down which are monster strong genes i worked with in similar conditions. Lets see how the strong sativas do compared to the indicas and hybrids.

A good idea for growing new places is to use bigger pots than usually in the vegetative stage, better safe than sorry.

go definitely with local strains. laughing buddha, higland lao, I will personally experiment with african sativas like original durban posion or so, just to get advantage of thin leaf structure.
as for the mold resistency silica is the key. slow release is the bes in form of some rock.
good drainige at the bottom of the raised beds, if you havent done it properly already. something like stones/vulcanic stones, or mesh, just to avoid roots from rotting. definitely airy soil, I will go with at least 30% of coco coir in the main mix, then you can put organic material on top that will slowly feed the ladies.
also there is symbiotic algae that you can spray on your ladies, they will guard them from pests and mold. hope this helps

Try adding rice hulls to the soil as well. It will aid in incredible drainage and has lots of silica to bring to the party. Cheers

could you go into more detail about the symbiotic algae? Looked it up and found a few species but nothing past that.
I’d definitely concur with coco choir. Especially in an area with lots of water. Coco choir should allow the roots to breathe better when wet, compared to regular soil… so it makes it harder to drown your plant.

I didn’t mentioned in my last post, I also growing in Thailand. We can keep in contact, the mixture you should use I will say 30% coco coir, 30% clay soil, 30%, 10% gravel in the bottom and add some agricultural lime.

Thanks! Lets keep in touch, always good to think with more brains 
I would watch out for mold and other bacteria that loves heavy moisture environments.

I have no idea about Asian bugs, but where I live, mold often comes from hatched larvae of flies and moths. They lay eggs in the flower, the little worm hatches out, then eats and poops. Mold grows in those places. The preventative is a bt spray, the bacteria that makes the worms forget to eat and then die. Bt is non toxic and harmless to people and wildlife.

UPDATE:
All of our 900 plants are in the vegetation state right now and will be transferred into the land in a few weeks.
Vegetation went well, good isolation in a green house safe from heavy winds and rain.
Will transport the plants into an elevated system on a big land with roofing for extreme rain and wind.
We are still looking for extra measurements to take regarding the high expected humidity levels. During growing stage but also while drying.
Any other tips or tricks are welcome!

Preventative compost teas spread onto your foilage will put a nice decent active layer of microbes on there that will fight against mold. Lactobacillus works well for that
