Hi all My first grow ever, I have a 9 week old autoflower in DWC in its flowering stage and I have been using RO water with added Calmag and Flora Trio nutrients its whole life (around 1/3 of the recommended dosage), no issues. Around 2 weeks ago I started getting sudden pH drops, it would go from 6.2 to 4.8 every 24 hours, yet the plant was growing nicely still. I ruled out Pythium and Algae, I did a res change twice and adjusted nutrients to no avail, the pH kept dropping, whilst still...

Hi guys, for the last couple of years, I've been playing with high-voltage electric fields to make the droplets within an Aeroponic system negatively charged and attracted to the root's of plants.

So as stated, I’m just curious how many people use reverse osmosis systems to draw water for their grow. I bought one when my ppm are only 160 out the tap, an now I’m debating on the purpose of if I should even use one. So I’m wondering how many people use tap water and who uses reverse osmosis and why?

I have a 50 micron filter at the intake and a 200 mesh spin down filter inline. I was wondering if anyone could recommend a small easily cleanable inline filter that I could splice in after the spin-down filter and before the pump?

Aloha, So I started some seeds I had on hand, (I didn't have much faith in the genetics) and these are the two females out of 6 I started. I had to pull the males out of the system once I identified them. But the roots were already so tangled I just got what I could easily and left the rest to rot, hoping the extra enzymes I added would help break them down. Both of these simple DWC systems have had identical treatment and there were males pulled from both, so both had dead roots but...

I’m almost in my 6th week of flower and I started noticing seeds in some of the buds . It’s only a few plants. I check the plants everyday I have seen no bananas or pollen sacs.

I'm finalizing my design for a RDWC run, and have some basic questions that may or may not influence my end build. 1) Does it mater how high up you place PVC on buckets? Can it be roughly half way up the bucket, or is lower better/necessary? 2) I was wanting to place the control bucket outside my tent, but the ports on the tent are higher than the level I plan to have the return lines on the buckets.

Long story short, I ran out of Hydroguard by GH that I have used for years in my hydro reservoirs. Stopped in a hydro store to get some and told that it is discontinued and that Aqua-Shield or something is gong to replace it. So the hydro owner told me to use Hygrozyme instead of the GH products at 3x the cost. Anyway I changed out the various res on my 48 plants in different stages of clone, veg & flower and ended up with slimy brown roots and a nute lockout. I have since flushed with...

Okay.... I finally got it right!!! I was able to figure out that GH FloraBloom most probably doesn't contain 1.5% Magnesium because the only water soluble source of Magnesium that is suitable for hydroponics is derived from Magnesium Sulfate. You can check that fact on Wikipedias solubility chart. Magnesium Sulfate Heptahydrate (Epsom salt) or just plain old Magnesium Sulfate will always be heavier with Sulfur than Magnesium. A 4:3 ratio approximately. So, when you make a mix containing 1.5%... GH FloraBloom DIY EXACT from Hydroponics / Aeroponics https://www.rollitup.org/t/gh-florabloom-diy-exact.528636/
