我唔識種豬睇相都睇到流晒口水=3
後面既討論雖睇完都完全唔明
不過心入面有個問題係咪即使做到溫度溫差就夠 ...
Lowest temperature required and temperature difference are 2 different discussion topics
Yes, we can only try to provide similar environmental condition for those highlanders in order to grow them in a home condition that is extremely different from what they are growing ~
atmospheric pressure, highest temperature, lowest temperature, humidity, temperature difference, light intensity, light composition .. all kind of things.
All adjustment to our home environment is costy. FL to provide light, humidifier to increase humidity, cooler to provide cool air temperature etc. etc.
Of course we wanna grow the plants up to their original sizes but most of us cannot provide all those that are equivalent to their natural environment owning to technical problem or financial problem etc.
We can only try modifying our growing environment that can grow them to their optimal ( might not be 100% of their original ) with our limited resources.
light intensity, humidity and air temperature are something that can be adjusted more easily.
Most of us will modify and observe. See whether minimal adjustment to our condition can lead to optimal growth that is close to their original sizes. Say modification of 3 growing factors that consume least resources can achieve 90% of their original sizes, why border spending some extra resources that are extremely expensive and difficult to upgrade the rest of the 10% to 100% ??
Especially no one did try experimenting which factors affect these highlanders' growht most. Why border put the plants on trials that are extremely costy but might not be efficient to achieve our purpose ?
Say, if a temperature differenece of 5 degree can lead to significant improvement of 90%, why border providing temperature difference of 15 degree ??
As only very few real highlanders can survive in such low temperuture, such low temp can lead to adverse effects to other plants that live in the same home together.
To me, I will try to provide a condition that most plants inside can achieve 60% of their optimal growth rather than providing one that only 1-2 plants can grow up to 75% while majority of the plants have to tolerate a 45% of their optimal growth ~ |
