What kind of lighting system should I get for indoor growing
« on: February 23, 2014, 02:35 PM »
I was reading a lot of information from mj growers, just because they've done a lot of research into the subject, but a few things differ from my situation.

1) I don't need to mask my use or covert op this growroom at all

2) I may not need the type of lighting they use which enhances fruiting and flowering, in fact, if there are lights specifically for that, maybe I should get the opposite or is it the case that the lights just make the plant stronger so they fruit and flower more, and if so, if I just prune the fruit/flower off, will i then get stronger growth from the plants?



These don't seem to be as costly, a 600 watt will cost about $.64 a day, I think partially because the magnetic ballast make the energy more efficient

Any info would be awesome!!



These are the current systems I'm tossing up-

You need a full spectrum for optimum plant happiness.  My vote would be an HPS / Metal Halide combo light if you really want to make it nice.  You can get the full spectrum (I've heard) with the right combo of inflorescent and incandescent bulbs.  Is this for overwintering?

Look into LEDs. China.

Owen, not for overwintering (I thought plants didn't need light for overwintering)

1st it's for the few tropicals (getting more) I have until we build the greenhouse. After the greenhouse it'll be for experimentation, seeding, orchids, and the tropical I keep in my room. Owen did you look at the options I put up? Definitely getting an HPS, MH system with magnetic ballast, but I'm tossing up whether 400, 600, or 1000 watts will meet my needs. My ceiling is about 12 feet in the soon to be greenhouse, and 9 foot in the room I'll put the tropicals. I will be replacing the fixture in that room with this lighting, and will be putting the solenoid on about 16 hours.

Owen, quick question, they say HPS and MH combo's induce fruiting and flowering. I was wondering, is that precision towards fruit/flowering at the cost of the growing we want as bonsai? Or is it the case that the plant allocates light as it wants, so if I pull any fruit/flowers as we normally would, is the energy redirected as it is normally when grown under sunlight?

I figured it was for tropicals.  It's not so much the light bulb but availability of the right colors. To keep the plant happy, my experience has been with a 600 watt HPS.  I would reccommend hanging the light not on the ceiling, but hung closer to the plants (say 4ft above for a lower watt system).  There are people far more used to growing tropicals indoors than me so I will defer to them for more feedback.

Yea that kinda leaves me still unsure Owen, the packages that I see for sale sells both HPS and MH, MH is for vegging, and weed growers use the HPS when they want it to fruit, however, I'm not growing weed or Michael Jordan or Jack Carrere or whatever else you want to call it lol. So I do not want waste my money on a system geared towards something I do not need.

Owen, With the 600 watt, did the plants flourish? Notice anything strange?

Actually Owen, take a look at this, this sentence caught my eye, this is what the tokers had to say about LED-

 LED Grow Lights

We've found that plants respond to LED lights similar to T5 fluorescent fixtures. They result in tight inter-nodal growth, and short stocky, strong plants. The plants do look a little different - the leafs tend to curl down. But the leaves are thicker and a more healthy shade of green.

Vegetative growth is a little slower compared to a 400 watt HPS light but are healthy and progress normally. Fruiting and flowering is also slightly slower but healthy and strong, with surprisingly dense development. The fruit and flowers are more realistic in color and are beautiful.

I would stay with the veggie growth.

Maybe flowering before a show, to give correct energy for flowers, but it is wasted energy for growing out.

Tokers are the only folks who care for plants as tedious as us! Lot of horticultural advancements from that camp.

Bonsaihunk.com.  Surprised you didnt research there yet. Great lighting info.

What Owen said about the hanging lights, definitely make them adjustable, the farther away the lights are from your plants the more likely it will be to have them grow longer and leggier. Everything I have read about grow lights (admittedly, not exhaustive) says you want to keep the lights a few inches above your plants if you can - otherwise they grow really fast trying to reach up to the lights.

I have a full-spectrum table top light set-up that works pretty well, they don't thrive, but it will keep things alive over the winter indoors until Summer when they can get proper sunlight.

I don't plan to grow a lot indoors, but I'd look hard @ T5 Fluorescents & Cool White (6500k) bulbs.  My 4-bulb T8 setup suffices for me right now.

Check out "Hotwired" 's thoughts on lighting for plants.  A LOT of his recommendations are for starting tomatoes, but he bases his recommendations on PAR.
http://www.tomatoville.com/showthread.php?t=25775


Plant biologists define light in the 400nm to 700nm spectral region as “photosynthetically available radiation,” or PAR.

Compare the images below: (the former a daylight fluorescent, the latter a conglomeration of several other lighting systems)

If you only want to over winter a few tropicals, and you have a sunny window, you really don't need to go to all that expense.  I have a EU olive, a BRT, and a willow leaf ficus.  All are growing quite robustly this winter on a shelf setup in my southern exposure window, that also has a regular shop light fluorescent fixture above the plants. I think the addition this year I made of seedling heat mats under the pots made a difference from prior years, where they basically just grew very little.  This year I even repotted the BRT and cut it back, and did a lot of pruning of the olive and both have put on many new branches, and lots of good solid growth.  In the winter!! So I don't really think unless you are trying to grow year round indoors, and you have a sunny window, you must have such additional lighting.  Just my experience.

There's not much difference between HPS and metal halide. MH will give you slightly shorter plants and HPS has more red light for better flowering. You don't need to have any supplemental lighting such as T5s. You can grow your trees just fine under either HPS or MH without anything else. There are also good LED lights coming on the market. You should hang MH and HPS lights some distance above your trees, at least 2-3 feet.

Thanks everybody for answering, it's comforting to see so many well-thought out responses, instead of- "hey you should buy a light"  ;D

After doing a lot of research, which included finding out that the spectrum bwaynef mentioned is the blue red range, I decided on LED's, they costs one-tenth the cost of HPS and MH, put out 1/4 the heat, are more precise by casting only blue and red light, are better for the environment, and bulbs last between 5-30 years (mine are warranted for 5 years of use). The link below is the one I ended up buying, except mine is 200W.

https://www.google.com/#q=Dirt+Genius+200W+led&tbm=shop&spd=2934101612152260816

Jlush, mine are just living as well, and now that you mentioned it, I think my main goal is to see if this will take the trees from living to thriving, I guess we shall see. I already have twin T5, and a 60 watt CFL cooking above my trees. I have, in my bedroom, a few orchids, 3 bonsai, 6 dart frogs in a vivarium which has a couple hundred succulents, baby tears, and others. The orchids, the frogs, and most of the inhabitants of the viv do fine, but the bonsai just linger. I will keep you all well informed on how this goes, I'll be running the led right above the 3 bonsai, reasonably close as they will probably enjoy the extra heat (which I'll be monitoring with a thermometer), I'll be adding the 3 or 4 other tropicals I keep downstairs to this number, and the cfl and T5 will also be casting on them, as well as two windows (they don't have great light, east facing). I will probably be setting up some simple shelf to keep them in this area...

Look at the crazy success this person had, and look at the size of the particles in his substrate!?This was the final tip of the scales to LED, I believe those are grow stones?

Those stones are hydroton/LECA.  I bought a bag last year and don't recommend it for bonsai soil.  Too large, too hard, ...and not nutrient-retentive enough.
