OK guy's starting out my first grow, it's going to be a scrog dwc setup,growing in a 80×80×200 growtent kit (I bought the cheapest one I could find). Not to bothered
about big yealds just looking for success. Here's what I got going on so far (check the pictures) my seed should arrive tomorrow or Monday so let's get growing.
It's all go now seed is soaked and put away for 12 hours in a nice blanket 🙃
OK so I think I cooked my seed it germinated and I swapped it into a jiffy plug and kept it covered with a dome I thought it was to cold so put it on the window sill for to warm up and get some light but forgot about it so temp went true the roof and the seed is no more (rip shiskaberry)....
OK so on to the next onwards and upwards dos si dos 33 let's gooooooooo.
OK getting there now a bit of fecking around at the start but hopefully I'm on the right track now.
Just put into tent under a small 16 watt led grow light to get things going. still under dome and not put into the dwc system yet as want it to toughen up a bit.
Any info on when to put (Dosi) into the bucket would be a big help as I'm winging it here and the more I read the more conflicting the answers get.
OK a bit of a major today. everything was going sweet, I was doing my first water change when I realized I had no ph down and my tap water is a steady ph8.7 I've added my nutrients and that brought it down to 7.6 still not great so added a little vinegar (i know its a no no and have been kinda told not to use it) its gone down to 6.9 let's hope it's good enough it will only be for two days let's hope it won't all go to sh#t. Shout out to hashy and
Please I need some help? I l was doing a water change (DWC) and can't find my ph down anywhere I think the women chucked it thinking it was trash. My tap water is a ph8.7. Is there a way to get it down without hurting the
you don't need "ph-down." Any acid will work as long as it doesn't screw with your fertilizer.
white distilled vinegar is a good option. It doesn't add anything as far as extra plant nutes or Na or anything problematic.
pH drift is not caused by the acid used.. it is caused by unbuffered solutions. I can add my nutes to anything from 7-8.4, from experience, and it comes out at ~6.0. It is stable and automatically balances out at 6.0 because i buy from a reputable agricultural manufacturer instead of some marijuna brand. they employ chemists and such vs some guy in a garage ignoring all common knowledge that existed before to do it 'their' way, lol.
So, if you have problems with pH drifting, blame the fertilizer and not the acid or base used to balance it out.
If you look at ingredients of those "ph-down" products, it's just citric acid and a few other options, lol... they are not more "stable" as i often see stated as a reason to overpay for a cheap product wrapped in a brand name for a premium price.
H3O+ : OH- ration = pH ... log scale. A weak acid is a weak acid but doesn't cuase greater fluctuation in and of itself. Stability of pH has to do with buffering. If the numbers that make up the ratio explained above are large, it will not shift easily and will dwarf any prior existing ratio, so it calculates out nearly the same no matter what (ph-balanced options do this, assuming they do it "right").
Turns out you can use a ton of shit you learn in school everyday :P pH stability is simply about numbers. 10:1 H3O+:OH- ratio being 6pH with 100:10 vs 100,000:10.000 is much easier to shift. The larger numbers mitigate any small changes to meaningless deviations, where as unbuffered can shift very quickly and for non-drastic reasons....
fyi, the numbers that'd we'd be working with are in moles... 1 mole is 6.022*10^23 atoms or molecules. BIG numbers... 1M HCl is 6.022*10^23 mlecules f hcl dissolved per 1L. HCl disaccociates 100%, so you get 1 mole of H+ looking to bond with h20..
1M HCl is a strong acid. Probably need 1/t0th of a mL or less per gallon... it won't be any more or less stable if youuse the appropriate amount to balnce your water to your target. but it would add Cl, which isn't great.
acetic acid.. no problems. cheap. no less unstable than anything else added that will balance your solution. Anyself-respecting hydro nute that isn't ph-bufferd is trash. for that rereason, and it's not new knowledge... that manufacturer is simply ignorant of common knowledge.
You can try citric acid powder(look for it in the canning section in your grocery store)to get by on but I'd order more pH down stat...citric acid isn't as stable IMO as the actual down and you're gonna get some wild fluctuations in DWC with it.
It's been some time since last post, this was a super long grow learned a lot along the way not to many f ups and plant looks and smells wicked. Sorry for not keeping an up to date log just not to good at it. Anyway here is some pictures still got a bit to go I think but getting close.
