when you took a pH reading did you turn off the airstone?
I notice when I take a pH reading, if I'm moving around the meter, or I have a airstone in the res, I can't get a accurate reading
im so tagedManaged to get some new pictures uploaded, so here are the pics. In the res tank - canna a+b, headmasta, drip clean, ec 1.64, ph 5.75
First up is the exo x nl at day 19, soon to be 20.
Here is the tangerine dream #1. Got to be some a5 haze or g13/haze heavy pheno, as it's also at allmost day 20, and though i think stretch has just about stopped, buds aint appearing yet.
She a really nice looking plant, and very vigourous, just looking a long one, plus i've had to tie her down, she'sover 4 foot now, while tangerine dream #2 is only about 3 if that.
Here is tangerine dream #2, perhaps a g13 heavy pheno, as both plants were the same size when they went in, allthough she hasn't been in aslong, its obvious she wont be getting much taller and even looks closer to starting to bud!. Bit of a creeper, looks a bit thin branched and sickly most her life, but is starting to look alot better and come into her own. She smells alot like oranges, definate orange smell. Not orange smell on #1, just funky. Allways have high hopes for plants, but have only ever found 2 worth keeping in 5 years and one i didnt the clone and the other was such a fast flowerer she was so hard to clone i lost her after only 2 runs. Maybe this time, who knows, would love to find something special, dont care where it comes from.
I don't understand how salt build up isn't an issue with these.
How does a person know the PH and EC of the each small res. under the pots?
They would both have to be in constant flux. The EC seems like it would just keep building up and up.
Must work somehow, because there are pics all over of huge plants growing in those things.
I wouldn't call it a res under each pot. The aquavalve allows a maximum of 20mm to fill in the tray, barely higher than the bottom of the pot. So it's sucked up pretty quick, I've not noticed any salt buildup as of yet, but if i do, its as simple as taking the pot out, and just washing the tray.
Flushing is where i am going to be a bit more confused. Do i bottom feed them still just with plain water? Or do you have to top water to flush? Or is just the plant drinking nothing but plain ph'd water for a couple of weeks enough. Will be one thing to test out this first grow and see how the lie of the land is. Hopefully, they will be great, just bottom fed plain water, if not, i'll just top flush from my plain water res when i need to.
