Lumens are additive. The lumen unit is defined by ANSI as an additive quantity. Think about it for a second. If lumens aren't additive, then the luminous flux of a panel of LEDs would only be equal to the flux of one of the LEDs from the panel.

I, too, was worried about heat buildup in the barrels. It seemed to me, at first glance, that there wouldn't be enough surface area presented to the earth for heat dissipation. I wonder if a below grade loop of a couple hundred feet of irrigation tubing between the water heater and the barrel...

The power supply for the computer may well be 1200 watts, but it's unlikely that the computer actually needs all of that power. So, the power supply is probably only really using 3 or 400 watts, top.

I wondering how airtight these things are when closed. I have an unused AC outlet from the central air that I'd like to feed into a closet but I don't want the air conditioner creating positive pressure when the exhaust fans aren't running. I thought I'd get a normally closed motorized damper...

Just don't do it. I find it very difficult to work by the green light. Of course, if you absolutely have to, the green light is the only way to go.

Ask yourself this; does the wind stop blowing at night? You don't want your circulation fan blowing directly on your plants. The goal of circulation is to mix the air. Good circulation eliminates high humidity at night, when humidity rises, especially as the density of the buds increase...

Businesses don't hire people because they get a tax cut (unless that cut is directly tied to hiring). They hire people because they need workers. If there is no need for additional labor, then the tax cut is just profit.

A "Scarlett Letter," perhaps. A big red 'A' that anyone who receives an abortion must wear for the rest of their life.

It's not that. I'm having to be around to help them out in their old age and they would never move out west.

Hey Shrubs, looking at pictures of your flowering area, it's hard for me to tell if your lights are fixed in the vertical direction or not. Are you raising them for the pics? If they are fixed, how did you decide the proper height? Love your work by the way. If my parents were dead, I'd be...

The medium is whatever the plant is growing in. Soil, coco, perlite and rockwool are all examples of plant medium. I mistyped in my earlier post when I called it media, as medium is the proper term.

This is so true. You can grow a 3 foot tall monster in a red plastic cup if you don't mind watering all of the time. I've seen pictures on this site proving that. I guess what I'm saying is that you'll know when to repot by how fast the existing pot drys out. If you let the media get a...

I always start seeds, of any type plant, in a small container. I have 8 trays of annuals getting established in red plastic cups, which I've cut down to about 2.5 inches tall, sitting in the screen porch right now. I determine when to move them to the flower beds by seeing if the plant slides...

Looks much nicer. Now take that streetlight and hang it outside.

At this point, they are just in the way. Let the big gun do the work. There just cluttering up your space as I see it.

So, you complain about people not responding to your point, then, in the post which directly addresses your concerns about family farms you concern yourself with a paraphrasing of Toqueville. What do you have to say about the rest of the post? I really tried to address your questions. I'm...

Given that a large majority of "family" farms were created out of land grants (where a society decides to give land, for free, to anyone willing to work it), I don't see a problem with society getting a cut during the intergenerational transfer process. You will be hard pressed to find more...

This has always made me wonder how we will be able to insist on being human in the face of our coming robotic overlords. Whom I welcome.

Profit and wealth are two different things. How much profit did you make off your house last year? (Ooops, I forget it's a grow website; you don't have to answer that) On the other hand, the existence of the dam has created enormous amounts of wealth. Real estate around Lake Mead alone is...

You are being entirely too generous with your timeline.
