coco ph level, how to test it

[oldman_67]

I've transfered the plants into coco, best thing I've done. I'm using a fairly cheap soil ph meter to test the soil and it came in at a touch over 6.

 

To get the most accurate reading should I water with ph corrected water and measure the run off? And if its higher then what went in put a slightly lower ph water next?

[bluntman_77]

you got it right , measure the run off , adjust the nutrient ph to suit . I generally find the ph of the coco runoff is higher and feed with ph 5.5-5.8 to compensate

 

you will need a hydroponic ph meter

Okay great, do you think I should wait till I pump the juice of the light back up to 600w, I turned it up to 300 today

Soil meter is crap. Just measure the ph of the run off as suggested. Always ph ya nute and waste water from the start.

what does this mean, didnt know u could choose the watts u wanted to put though a light, if ya bulb is 400watts use it as 400 watts if its 600 watts use it as 600 watts.....

 

and yes u know coco is hydro so how come ya still using the soil ph meter thought u ordered a ec and proper ph meter like 6 weeks ago

 

seems alot of wasted time in tryin half ass methods n trying to save a buck...do it right as we have said in lots of posts in the past and start to reap some rewards finally

 

 

and yes, to measure the ph of ya gogo u measure the runoff

[oldman_67]

I have,

 

And it has a dimable ballast.

hit the 600w switch

Also grab one of those TDS/PPM meters off ebay - well worth it.

Here is what you need, this is the meter i use and find it accurate and reliable. less than $10 including delivery from Hong Kong on EBAY.

 

Don't bother measuring the runoff, its a waste of time.

 

Get the E.C. level of the nutes right, get the PH right, allow 20% run off when feeding and the rest is history

dont buy cheap buy once. dont be like me buy 1 off ebay then buy a blue lad truchean meter and find out its .4 out do it once do it right
