Hi folks, I'm sure that there are plenty of more skilled electricians and engineers on this site than myself, but I wanted to start a thread to help keep our DIY electrical systems safe. Bottom line is we are taboo in some strange, sad parts of society, and we need to keep each other safe. I've...

Hi all, I just wanted to share this. I'm sure the link has been found before. But I am going to stitch one of these up as my new reservoir chiller and will share results along the way here.my goal here is to build a cheap water "heatsink" with environmentally sealed electronics and high...

So a lot of the Gerber baby water and shit I see at markets are purified through distillation or reverse osmosis, they're fluoride free, and they contain Magnesium Sulfate, Potassium Bicarbonate, and Calcium Chloride... that's it. Anyone try using it? From what I know these are all really good...

C12H22O11+H2O2 =CO2+H2O... amirite? A friend of mine is using a solution made up of peroxide & natural cane sugar to add to her recirc system. Anyone know what kinda magic this could work on her system? Feedback and pics are appreciated (also science!) :D

Just want to let y'all know that running a DWC system using all distilled is baaad. After about 2 months of using a distilled sterile UC RDWC, and switching over to 75% filtered tap/25% distilled, many problems have been alleviated. The pH is now stable between 5.6 and 6.0. The PPM is dropping...

These are a few pictures that a friend was asking about. She was asking if these looked like these were ready to be flipped. My opinion was that even with the stretch from flowering, she wouldn't reach her goal of a 1.5m x 1.5m canopy. They are both in 19L buckets and still have plenty of room...

HighLifeSeedBank.co.uk lacks customer support, and won't help you recover anything lost in the mail. Wouldn't recommend these guys to anyone. Stick with Humboldt or Holistic Nursery

Hey y'all. I've noticed that sometimes plants will get a bit of a yellowing at the tips, and then rust/brown spots appear. I've seen them completely overtake a set of fan leaves already, and it only seems to really be affecting larger/older growth. pH is on track, as well as reservoir temps...
