@Isochroma I have a couple of questions for you as I had made something similar, but even more DIY then this. I was wondering how you calibrated the temperature, did you use a trial and error method? How do you clean it? The vapours may be cool, but wont the vapours floating around inside...

The last time I had to waterproof something for electronics, I used some liquid tape.

You can get K-Type thermocouples off of eBay incredibly cheap, like, less than $5 each. At least -50C to 250C, perfect for this kind of application. You can use them in water too, they generate a voltage based on temperature. The only problem I can for see is that they usually output a small...

All the seed banks I have been to have said White Widow has a flowering time of 8 to 9 weeks.

I noticed you were talking about galvanic moisture monitoring, this isn't exactly the best way to do it, as you will slowly leech minerals from the rods into the soil. I found this link to a DIY Moisture Sensor (resistive) after searching for a replacement for one I used at a friends house that...

I jumped from page 2 to 6, so I don't know if you solved the heating in the shed issue, but if you painted the roof white, or covered it with a white material, it would help reflect a lot of the sunlight away.

Does a GFI work with 3 phase though? In a delta system, there is no neutral, only live 1, live 2, live 3 and ground.

Sorry, but I don't know enough about 3 phase to help you out. I learned a bit about it in some industrial controls courses, but it mainly focused on PLCs. You'll have to wait for either brick to answer you, or for an industrial electrician to come by. Although, I can say that from what I...

I said that based on what is in the description in the link you provided, and I assumed there is a adapter socket in the package, maybe on the back side. But I did a little bit of research, and I found that they do make screw-in adapters for PL's with a GX24 base, which is what the bulbs you...

If you mean HPS or MH, then no you can't. Ballasts are meant to limit current because the bulbs can't do it themselves, so they will eat all the current they can until they burn themselves out. If you stick a 400W HPS bulb on a 600W Ballast, it has an extra 200W of power it WILL use, and more...

Only the 2nd link worked for me, the 1st one said the product wasn't there anymore, but I'll assume it was a PL tube also. Ok, so, you want to use PL's, which are Compact Fluorescent lights. Most compact fluorescents have the ballast built into the base. According to the description of the 2nd...

Firstly, I like to make as much as possible on my own, that way, if it breaks, I know how to fix it. Secondly, I have yet to find a complete cooltube system for less than $100, that includes the glass tube, reflector, exhaust fan, ducting, and the rest of the hardware needed.

As long as the exhaust is pulled out through the top, as hot air rises, that should work fine.

As far as I know, cooltube "systems" are sealed, as in, air comes in from the outside, through ducting, into the glass tube and around the bulb, then out through an exhaust carrying away the heated air. It is never open to the room/closet/cabinet. That way it the bulb never heats up the...

I helped a friend set up a 10000 watt (10 1000w) system. We did it over 6 months to lull suspicions. Suddenly jumping to 10000 watts is very suspicious, but gradually getting up that high over x number of months isn't as bad. We also had another 100A service box installed under the auspices of...

I would start small and work my way up.

Here is a fact, buy some solar panels or a wind generator, and offset your lighting power usage with renewable energy!

You can make your own cool tube quite cheap, using a candle shade that uses hurricane glass, like the one in the link below. That, and some ducting, and possibly an inline fan would be perfect, and is what I am going to use. The Fan is a 12V 5A (60W), and I am going to buy a few of them and...

I don't think it is too much, I am just saying I don't know what level of power usage will cause your power company to question what is going on. Realistically, I could say that power companies don't expect high power usage between 8pm and 6am. However, 5000W isn't that high, and I don't think...

All I can say about this is that I do not know the policies of your local power company to say whether or not they will be suspicious of sudden increases in power, and what their threshold for notifying the police would be. A couple of ideas I have always thought about, if I ever went big, is...
