the hydro threads are in the hydroponic cultivation section. If nothing's showing up, it's because there's a really annoying time setting thingy that hides them after a few days without posts. Anyhoo, there's a nifty little search/scroll thingy at the bottom that allows you to search through thread archives from within the last few days, weeks, months or since the beginning of the forum creation. So, assuming your web-search link click is not irecting you to the main page, at the upper left corner of the forum page, you should see "Growkind.com Marijuana Cultivation Forum. Click on that. It'll direct you to the forum category menu where you can choose between pages like the beginner's lounge, advanced cultivation, hydroponics, outdoor, organics etc.. Click the category you want to read and if the older threads are buried just use the tabs to search through archives. They're at the bottom just below the listed threads menu.
You can change the settings in your user cp to include posts from further back. I have mine set to show all the threads active within the last month. I see plenty of threads in the hydroponics cultivation forum, which is where this one is posted.
Looks like you were directed nicely. :thumbs-up:Let us know if you still have trouble getting around the boards. cheers,
