400 watt HPS grow light...
    #3786877 - 02/16/05 01:20 AM (11 years, 9 months ago)

I bought a 400 watt HPS grow light earlier today from a smaller local greenhouse for $100.It was a demo model they had up for several months and since I frequent there often enough, I got offered it and they threw in a new HPS bulb.I am going to pick up a MH conversion bulb to go with it (or order it if I cant find it locally) sometime this week.

My questions being:
A) Is this a good price for the grow light system?
B) What height should it be suspended to above the plants?
C) How much more growth is there VS fluorescent lights?

I know the differences in lumens but I mean is the growth increase dramatically more?

for around here that is a pretty good price. especially with a new bulb.

im no hemp expert but people im around usually keep it 1-2' away during veg.

im a fan of flouros, but for the money hps/mh setups are better and way smaller. from what i have setup its been way easier to use teh hps.

A) Yes this is a good light to grow with, at a decent price. A new one would cost about $140 CDN. It will work best in an area of 4' x 4' giving about 50watt's per sqare foot. Perfect for those sun loving plants...

B) I would put it about 18" from the tip of the plants

C) a 4' fluorecent tube gives off about 3000 lumens per sq/ft. a 400w hps gives about 40,000 ( some say 50,000 but that is with a brand new bulb )

Yes, you notice a dramatic difference between fluoro's and HPS.

I was using fluoros to grow but the growing area was relatively small and some plants that need a lot of sunlight didnt do well at all and the other plants grew slowly under fluoros.I decided to upgrade since I need a faster growth rate.Thanks for the advice.

(nods) Good.I need to see a better growth rate than what I have under fluoros.

Thanks for the advice.

Nice find. Im sure you will be pleased. As far as the distance you should set the light goes, it depends what you are growing, and how much of it you are growing. If you are growing cactus, I would bring it down just as close as you can get it while still illuminating all plants.
Also the MH conversion bulb is a good idea ( although pricey). You should really be seeing a dramatic increase in vegetative growth.

Thanks.After doing some searching via google I found that the 400 watt mh conversion bulb is only $40 @ http://www.insidesun.com/index.php?action=item&id=150

Although the normal 90 to 100 dollar price tag isnt bad IMO.

Yeah, insidesun is a great site. I wish I had the room for a grow setup w/ HPS or MH lights. Those prices are great.
Right now my setup consists of a bookshelf, with flouros on each level, and a shade on the outside to reflect light back in. Small, but effective for the cactus I grow.

I would just go for a Hortilux bulb instead of a MH conversion.

One of my best friends got jerked around by inside sun for months. His order lagged, the first light system he got from them didn't work at all, and the second one turned itself on and off whenever it felt like it.

Check out discount hydroponics.

If you have an air cooled hood, and you're growing MJ, you can get the bulb less than 18" away

BTW 4x4 is too big for flowering in my opinion.

4x4=16 Sq. Ft.

400 watts/16 Sq.Ft.= 25 watts/ Sq. Ft.

somewhere between 2x3 & 3x3 would be closer to the alleged optimal 50 watts/ Sq. Ft.

2x3=6
400 watts/6 Sq.Ft.= approx.66 2/3 watts/ Sq.Ft.

3x3=9
400 watts/9 Sq.Ft.= approx. 44 1/5 watts/ Sq.Ft.

Yeah, I have heard mixed opinions on inside sun. Some say it is a good site, others say they will never shop there again.

Yea Ive heard the same, From what i heard they were back-ordered about a year ago and yanked a few people around for a month or two. I havent heard of any recent problems with them.

I ordered the $125 400 HPS from them last summer and it came a week later.... They are the cheapest source for a system.

A 400w can cover a 3x4' canopy well in veg, but in flower you should put them in a space around 2x3. You want to bring the W/ft up around 60-80 depending on your growing conditions like ventilation, hydro/soil, Co2 Enrich, Bowl/stadium/Scrog/SOG/bush ect. The more love you give them the more light intensity you can give them.

Floros are good for veg, but you need to constantly adjust the plants and light height so the tops are right up in the bulbs. in flower you cant compare floros to HPS, though i have seen many good grows under floros... its just you dont get much in the end after all the effort... Unless of course you have allot of bulbs and well trained and cared for plants.

You would really be surprised how little wattage you can veg. under. If you're in a $ crunch, I advise you veg. under compact fluoro's. They have 99 cent 23 watt c/f bulbs at Home Depot, and you can buy a fixture with a reflector and a clamp for about 6 bones.
The growth rate difference between HID and fluoro is big, but don't poopoo the fluoro's now. They can still be quite handy for rooting clones and micro grows.

If I were you, I'd get me an air cooled hood, a small blower(between 200-300 cfm) and one of them C22 mill's pride cabinets to stuff it all into.
