Flourescents can be put right up against a bine, which will produce plenty of light, especially given the amount of light for the money.

Flourescent "Grow" Bulbs of varying wavelengths can be bought at Lowe's.

I bet 4 4' lights would do quite well if there is any natural light at all.

The problem with the grow light is they put out less light than the cool and warm bulbs. The below data is from bulbs.com. Not only does the plant light give less than half the light, it costs 4X as much ($3.09 for the reg., $12.39 for the plant). A mix of warm and cool will give almost the same spectrum, so for 2 bulbs with 6000 lumens for $6 or 2 bulbs with 2700 lumens for $25. This is what many of the labs that study plants use to grow them. It's what we use for tobacco and arabidopsis. Now field crops, they require lots of light and typically require fancy halide lights if you want to grow them in the greenhouse (out of seson)

All 40W bulbs

Plant 1,360 Lumens

Cool White 2,970 Lumens

Warm White 3,040 Lumens

I added photos to the beginning of the thread so you can see my crazy indoor hops experiment.

You are totally crazy! I love it. Please move out where you can actually have a bit of land.

I actually do have cascade, willamette, and sterling planted at my dad's house, but since it's about 20 min away I decided to try the indoor project to cater to my crazy/obsessive side that wants to watch the hops all the time.

In addition to large quantities of light, hops need a cold period in which they go dormant. The cold period should last around 7 months out of the year, so you might want to put them outside after harvest.

That's good to know, but I may have to clear up some space in the fridge for the rhizome, because during an Alabama winter, it will be 30-40 for 4 days and then 60-70 for a couple, so it may not stay cold long enough.

Looking at your pics, they are clearly not getting enough light. The distance between each set of leaves is a sign of stretching. A plant receiving sufficient light would put more energy into leaf production to harvest as much energy as possible...yours are producing stems in a vain attempt to get closer to a sufficient light source. Even if you can keep these plants alive with the light you've provided, you won't get a harvest to make it worth the effort. Add more light while you can, and you might be able to salvage something.

They won't do quite well on a 10'-12' plant. Their intensity diminishes rapidly at distance. They might be enough for a small plant, but once it gets bigger, more light will definitely be necessary.
