catweazle1 Posted May 12, 2020 Share Posted May 12, 2020 @shire Yes, but how would one ascertain the cause, especially a neophyte, without one? 1 Link to comment Share on other sites More sharing options...

It does help to tell you if you are over feeding though by giving you the option to test your runoff. If you are going to get one i can recommend a blue lab truncheon, ive had mine years, bomb proof and no need to calibrate just clean it occasionally. Does the Bluelab do PH too?

BonnieAuto Posted May 13, 2020 Share Posted May 13, 2020 @Professor_XWhen I moved to coco I thought it would be smarter to spend a extra £10 on nute's and get advanced nutrients sensi coco with "ph perfect technology" than get a £80 piece of kit that I am likely to fuck up using/drop. yanks love them.

Save's you buying EC and PH pens You mean an extra 20 quid for grow and bloom and how long will that last? It's supposed to be pH balancing, so it doesn't negate an ec pen.

BonnieAuto Posted May 13, 2020 Share Posted May 13, 2020 (edited) @catweazle1 I'm using bloom for my plants in veg atm, I doubt there is much between them £80 for ec pen and depending the way the you choose to ph, the blutab ph pen is £65, those pricey's made me go for sensi's stuff and used the saved cash towards a 8" EC stealth extractor. From Advanced nutrients themselves "when using our pH perfect line of nutrients, There tend to be many other components besides dissolved fertilizer in the water. (eg. pH buffers, humic and fulvic acid, amino acids etc...) Because of this, an electrical conductivity (EC, TDS, PPM) reading can be difficult for the grower to properly ascertain. Instead of reading the PPM/EC, we recommend following our nutrient calculator, but starting off at 1/4 strength of your base nutrient for small clones and seedlings, Gradually working your way to full strength as the plant matures over a period of 3-4 weeks." also the nutes are "chleted" making them available to the plant at a wider range of ph, nothing is "balanced" my young grass hoppa That's the way I looked at it starting out...... unrelated but that fan packed in last month Edited May 13, 2020 by BonnieAuto 1 Link to comment Share on other sites More sharing options...

iShouldCoCo Posted May 13, 2020 Share Posted May 13, 2020 You can get away with it - I'm currently on my 2nd coco grow with no EC or pH monitoring (Canna A/B). It's risky though, it could take you a few harvests to get a feel for how your water and nutes affect your plants, and you might get disheartened and give up before you get it all dialled in but if you want to rely on data rather than guesswork and trial and error, get an EC pen. It'll be one less unknown when you have issues with your grows. I did look up the water measurements for my postcode area and used that for my starting assumptions and also feed less than the recommended dosage on the Canna website. 1 Link to comment Share on other sites More sharing options...
stummer Posted May 14, 2020 Share Posted May 14, 2020 If new to growing for the sake of a few quid get yourself a decent ph pen and ec pen imo. Better to learn the basics and get some experience under your belt. Best of luck with the growing, hope it goes well for ya. 4 Link to comment Share on other sites More sharing options...

Mon then i'll take the lot of you do I sound like a cunt if I say 170 these days is just a few quid? Not that I'm loaded because said before money depends on where your at at the time. A tenner when your skint has more value than a bullseye when you don't it. Just these days 170quid doesn't go that far. Anyway I can't comment on the other type of nutes as just always used canna. Seems like there are options so just need to decide what works best for you. Best thing I would say is keep it simple, stick to the basics and just get some experience. 1 Link to comment Share on other sites More sharing options...

I just had my biggest harvest, so I am happy with my level of risk. Curiosity and science will drive me to buy an EC and pH meter at some point soon though. I am in the process of switching over to Plant Magic Coco, so not planning on buying any more nutes this year but I'll bear that in mind. "It's risky though" and "get an EC pen " are the takeaways from my comment 1 Link to comment Share on other sites More sharing options...
