If the budget pen calibrates properly at 2 points (in our case 4 & 7) then there can't be any difference. If you put them in the same solution they would read the same, so not sure how Bluelab has better performance at measuring anything - they just last longer. When they do break, and yeah Bluelab stuff does break, you can get the repaired or replaced for free - the lifespan and warranty are the main difference (and possibly not need to calibrate so often). Don't get me wrong I love Bluelab equipment, but most people just don't need it.

Ah, cool - not seen the budget ones with the screw adjuster before, thanks. The auto calibrate version of that pen is basically worthless, I went through 3 and they all worked for a few days then died.

They are excellent but for most people the price is simply not justified - as long as you calibrate the pen I linked to above once a week it does exactly the same job as the Bluelab equipment.

Mix with one 70l bag of it with about 3-4kg worm castings for best results. https://www.lazada.co.th/products/i1897682199-s5961880190.html?urlFlag=true&mp=1 Also a good idea to add in some friendly fungi if you haven't added it by then: https://www.lazada.co.th/products/i2809076077-s10238236549.html?urlFlag=true&mp=1 Other things you can add are rice husks (very cheap here and a good source of silica which plants love) and Fulvic acid, although I add both Silica and Fulvic in liquid form with the feed to make sure that they get enough throughout the plants life - they make a huge difference. Totally agree with the heavily fertilized soils here (we used to call them hot soil in the UK) - they are OK if you know how to read the plants but yields are always low. Quality can be good but very hard to control the feed to a level where the plants don't get nutrient burn and lockout.

If you want to grow premium cannabis you will need to grow with 24hr aircon here in Thailand. Temps should ideally be 26 degrees C or under. BUT - temperature is not the biggest issue as aircon is everywhere, growing indoors in Thailand is all about humidity control. If you are in week 4-7 of flower and you let the humidity go above 40% you are absolutely asking for bud rot - it gets every grower here sooner or later. Some aircons seem to be able to deal with the humidity whilst the air is being extracted, others not so much. You will need to set the the growing environment up and test thoroughly first to see if your aircon can handle it, most I think cannot so dehumidifiers will be needed. If you just grow 3-4 plants in an open tent/room then you will not produce dense enough buds for this to be a problem, but if you want to grow the premium weed then you absolutely need to focus on humidity control. These are worth their weight in gold: https://www.lazada.co.th/products/inkbirdihc-200-10a-i1180092435-s2797328741.html

For accurate PH/EC calibration these are what you need: https://www.lazada.co.th/products/i1978886344-s6332054048.html?urlFlag=true&mp=1 https://www.lazada.co.th/products/ec-meter-14-mscm-005-mscm-120ml-i687184202.html A good PH/EC pen for the money is this one: https://www.lazada.co.th/products/i122609286-s127996867.html?urlFlag=true&mp=1 I really prefer the screw calibration over the auto calibrate type as you get finer control and they are way more reliable overall.

Morning All, Just found this thread. I owned a large grow shop in the the UK from 2003 to 2017, I have a fair bit of knowledge on the products for growing cannabis and how to use them. I'm not great on the chemical analysis side of nutrients as we tended to sell ready made nutrients that just did the job without the end user needing any knowledge of how they worked, but I do have some good knowledge on what is available in Thailand in regards to cannabis specific nutrients. Lights, fans, filters, plant problems etc I can really help people out with any questions. So any questions please let me know, happy to help where I can (PM's are also fine). Cheers, Tom.

Any recent info on this school - I'm thinking of putting my kids there in May (3 year old in the nursery and 6 year old in P1). It's less than 5 minutes drive from my house so the school run or lack of it is a massive plus, would be great to hear from any parents with kids there currently what they think of it. Thanks in advance.
