Northnutstarted grow question 5 years ago
Can anyone recommend me a fairly inexpensive but accurate ph meter? I ordered one from amazon (the best seller) and upon calibrating it it's so all over the place with its readings. I need something I can trust and dont have to calibrate all the time?

HM PH meter. I bought it from my local hydro shop at 50 bucks, 40 on Amazon, and found it holds its' accuracy pretty well. There is another waterproof model for more money. I used the older yellow/cheap ones from amazon and they are all over the place... This one I check every couple of days and it will normally raise .1 over 10-14 days. I use GH hydroponic solution (7.0) to check it... If you wanted you could leave the PH meter (the sensor) in the PH solution all the time, as you are supposed to keep the sensor wet. I tried it but ran out of solution pretty quick.. so I stopped doing that. happy growing! 👊

Hi. I my opinion the inexpensive and accureate dont fit together. The cheaper ones you have to calibrate before every use. and i did not find a single one that was user friendly. If you think about growing more often weed and need to get your Ph you may think in investing more money for a bluelab ph meter..... in my experience the most user friendly and accureate ph meters on the market.... cheers

Hi @Northnut! Support your local growshop! First, this is country related, since we have various brands & models accross the globe. Next, your amazon pH pen is probably a cheap chinese crap, whereas you can find plenty of advices and reliable products at your local growshop. And in case you live in a place where there's absolutely no shop, I'm sure there's a good online growshop in your country! BlueLab is a good brand I can recommend, but not the cheapest. Hope this will help, happy growing! 👊

Yes I can CityFarmers ph meter I bought over a year ago and still works good. I do recommend buying pH calibration liquid solution a 4.0 and 7.0 is all u need. It makes it easier then trying to mix a powdered pH calibration. You just pour solution in a small cup and put pen in if it's out of the range it should be slowly calibrate till it's right.

Aplicar defoliación??Veo que ya tienen muchas hojas.
¿Me recomendáis una defoliación?
No me atrevo, ya que no quiero extresarlas mucho y frenar el crecimiento en ésta última semana, aunque creo sería bueno para que penetre mejor la luz.
¿O bajo mejor un poco el foco?

LST or defoliation on autosI think I will need to defoliate a bit those bushy ladies, but I am not so confident about that because, from what I've read and since it's my first time growing autos, defoliation or lst is not advisable because it may stress them a looooot or am I wrong?3 years ago

DefoliationWhat do you guys think about removing the 2 top leaves too give the lower branches some more light too come out? Would this be bad for the plant or would it be fine ? I’ve already removed the 2 first leaves that first sprouted on the plant and it didn’t seem like it affected it

DefolationHey all can anyone tell me when to defolate my GSC she's now 41 Days from germination.
She had thrips started at week 2-3 that's why she stressed a bit and bloom later. Preflower started 2-3 days ago, and now I don't know about the stress again or should I wait 1-2 Weeks more?

ScrOG / Lollipopping / DefoliationI'm thinking of going for ScrOG for the blooming (which is just starting) – maybe even lollipopping or defoliation.
I would love to get some feedback!
- What I should bear in mind?
- Does my setup look suitable?
- When should I start with what?
- Any good resources?
