Another good idea. My biggest concern is pH, though. Not sure if it's just my tap water, but it seems to drift upward even after many daily additions of the pH down. It seems there would be no inexpensive way to automatically adjust pH.

FYI, this is the water pump I got, and when I tested the setup it averaged more like 40 gph than 80, but that is fine for watering, probably better even https://www.amazon.com/dp/B00EWENKXO/?tag=skimlinks_replacement-20

Just thought I'd share my automatic watering setup. Res has an air stone and small water pump, with the water pump set to run 3 minutes every other day, which seemed about right based on my testing of the setup. The hose has lots of holes drilled in it so it drips and sprays all along that...

I like these ideas. I am on that vacation now and I did end up starting some seedlings before leaving. The attached photos show the gist of the setup, though you can only see half the plants basically. There are two in an 18 gal tote, one in a 7 gal bin, and one in a 5 gal. I spent days...

If you have an Android phone, Open Camera is a nice camera app that gives you way more settings than the stock app, stuff like color balance, ISO, lots more. If it's an iPhone then I can't help you!

Just a few photos from around the canopy. Trichomes are starting to develop nicely. Hard to believe this thing is only about halfway done, it's gonna be very nice by week 13.... Last photo is the freebie. It's showing some signs of nute burn even though I've only fed once pretty lightly. My...

And in case I wasn't clear, I won't be adding the second container for a few more weeks anyhow, and right now I have almost 7500 lumens per square foot. So more than adequate for the one container. I was hoping to put in the HPS at the same time as the second container and then upgrade exhaust...

I wasn't suggesting I would try to light that whole space with CFLs or choosing between upgrading and not upgrading my lights. I just was trying to calculate how much hotter (the number) a 400w HPS would be compared to my current setup. I realize a can't use CFLs for that whole space, that's why...

I would agree, though my progression is usually to add one or two more bulbs every time the plant gets big enough that even a single leaf is more than a couple inches from a bulb. So seedlings start with one bulb (26 or 32w) until their second or third node, when I add a second bulb. Around...

Looking good!

Yes, more heat, but right now my maximum temperature is around 75F in the grow room vs 65F ambient, so I could take some more heat before I start pushing the limits. Plants might even like it. Come summer, I will certainly need a new fan, but I should be able to get one by sometime this spring...

I don't mind turning my head sideways! If you have an Android phone I recommend the Open Camera app, it's better than stock camera and let's you change the setting as far as whether it adds a rotation tag or actually rotates the image. I think that's the problem: your phone adds a tag indicating...

Took some macro photos last night, posted in the photography section: http://www.marijuanapassion.com/forum/showpost.php?p=914264&postcount=8 Those were taken using my cell phone with various lenses I scavenged from other sources clipped to it.

Other people say it works fine. This particular plant was a stunted mutant so it had lots of problems.

Thanks everyone. The problem solved itself when the plant hermied. I'll start the next bucket sometime after I return.

I've used scavenged lenses from laser pointers and CDROM drives, which should be similar, and they work well enough. I just posted some photos using that method.

Check out my DIY microscope thread if you want to use your phone too. Photos won't be as nice as DSLR + tripod, but you can see from my latest photos you can definitely check the trichomes that way. Those were handheld, if you build a stand for the phone and clip samples I bet the quality would...

Thought I'd follow up with some new photos taken with this type of setup, using a few different lenses of varying strengths (CDROM lens, laser pointer lens, lenses scavenged from digital cameras, and some LED lenses. The highest power isn't really best, it's too hard to focus. Mid-range seems...

It may have just been a hermy genetically then, that plant had all sorts of weird issues that none of its siblings (raised in identical conditions) seemed to encounter. When the cotyledon opened there were no true leaves inside, and it sat there for over a week getting basically no...

Yeah I mean that's why I called it an "upgrade"... I'm just trying to decide whether I can get the light without a new fan or whether I'll need to buy both at once. I guess I can start with the light and if it gets too hot, just switch back to the CFLs until I can get a better fan. I've...
