Answers about CFL, HPS, How Much Light...

I no longer grow using a 1000 watt system. I'm now just a 670 watter. I took one of my old super sun reflectors and cut a hole on the opposite side. I now have an eye 400 blue on one end and a 270 watt super agro on the other. Makes for a pretty good over all spectrum. And I get get almost the same yield as before with a mover.
By the way, in regards to the 1000 watt compared to the, 600 and 400, there was a drastic change in plant and bud structure.
I have my grows pretty damn dialed in, but I'm no pro. It's just a hobby for me.
Peace

Crap. I was about to make this a sticky and it got off topic. I'm going to pick the individual Qs out, give them their own thread, and stick this. It will be useful.

Gundari; You really want the 'Daylight' bulbs for vegging. They're 6500k and emit a full spectrum for maximum growth. Come flower, I think numbers could be argued, but you'll want a few 3500k 42watt CFLs IMO. For flower; I guess you could say the redder the better;)
Good Luck!

Nice thread; keep up the good posts:thumbsup:

Growbe how many plants do you have inside that sunroom? also what sq. footage is that and how much light covers it? I noticed you made that growroom yourself and inspired me to use my pragmatic ingenuity in creating my own. Im fairly new though, only having one solo grow and wanting a bit of experienced advice.

i have a question...dutch pimp was saying 6500k for veg and 2700k for flower but im looking at 1000bulbs.com and they have MH at 4200k and HPS at 2100k will that make a difference at all??

No, the MH and HPS are fine like that. The HID lights have their own rules...:D...MH for veg....HPS...for flowering.

The 6500k and 2700k are the preferred color temps for CFL's.

If someone runs a New wave T5 4' long by 21" wide with 6500k bulbs that all contribute to 40k lumens, would that be enough to flower also?

INSpectadeck...there are 144 square inches in a square foot. so, for your area,

18" x 18" = 324 sq. in.
324/144 = 2.25 sq. ft.

You've got 2.25 sq. ft. Really, you want to have at least 4000 lumens per square foot...5000 and up is better. At 1600 lumens per bulb, you should have 6 bulbs or more. In that small of an area, I'd try it with 6 bulbs and make sure that the wall surfaces reflect well. Check out some of the Rubbermaid grows on here...they have grow areas similar in sized to yours. See what type/how many lights they use, and how they did.

turksteelman...yes, you'll do a GREAT job with a T5 like that. 40000 lumes is good for 8 sq. ft. with no problem...that's 48" x 24". And you can use the T5 in flowering too...just switch out some/all of the bulbs for 3000k bulbs. HTG supply sells those for 4 for $20.

High Tech Garden Supply

Good luck to both of you!

I have a 400 watt MH setup from HTG Supply. What kind of results will i get if i try flowering my plants with this bulb compared to a 400 watt HPS or with a conversion bulb for my current setup?
