1st grow would like some help 90watt ufo 400hps

Thanks Man I have been reading day and night for a month now. I will check the stickies.

Nice setup. Very nice. I really like the use of PVC piping. I've seen it a few times but this is the clearest implementation I've seen. I'm gearing up my room and will be using your PVC build.

Thanks Dude that very cool my me. I bit it from someone myself. Cost @ Home Depot. 3-50feet garden wire $45, 1 1/4 tee 8 x $1.27, pvc 40 pepipe 6 x $3.46(pvc was like 10 feet long). I will take some Pics close ups of the PVC.

If I have to re pot next time I will. I have to see how thing turn out.

Dude my space is to small for horizontal scrog. But I have not ruled it out.

4. Did you research the UFOs well? They receive very mediocre reviews, especially the previous generations. Search these forums and you will find very good LED information. There as some LED wizards here who have documented what goes into a good LED setup. I am not sure what generation light you bought. You might consider returning them and getting something better suited. You should be able to replace your HID with the right LED setup.

Research was limited due to lack of info. I bought 2 90 watt ufos. 4th & 6th generation. 1 tri band, 1 quad band both 660nm. Cost $135 each
I took a picture of the light before the 400hps came on 4-23-2010. check the red light on the plant. The farther the light from the plant you will see the red on the plant get bigger. The closer the light gets. The smaller the red light on the plant gets. For now I am going to keep the light a good distance from the plant. Dude I don't Know.


2. What is the two bucket method?

Use 2-5 gallon buckets. Top bucket has a 3.5" hole in the center. That is used for a cup (with slits in it) to wick the water up from the bottom bucket. The white pvc pipe is used to water the plant via bottom bucket. You can never over water using this method. Plus you water 50% to 80% less. The buckets suppose to work like nature. Where the plants get water from the bottom up. Rather than having water poured on them. I'll take pics and find the web site I got it from. 2 kids trying to save the world. Gonna help me GROW SOME WEED.

CLOSE UP PVC SCROG SETUP EASY TO MAKE.

Cost @ Home Depot. 3-50feet garden wire $45, 1 1/4 tee 8 x $1.27, pvc 40 pepipe 6 x $3.46(pvc was like 10 feet long). I will take some Pics close ups of the PVC.

You could go cheaper on wire.

Yo that rocks. Thanks for the details! I'm going to document and do a tutorial on this cribbing this thread extensively when I build mine ;) Too bad about the space. I hear you. I see no reason why you couldn't angle the LED

Others more knowledgeable than I will weigh in with some LED info. You'll find it in the forums too. I'll try to dig you some links. I found this when reading the "what do they mean... sticky today. It dates from early 2007:


LED â?? Light Emitting Diode. No really, Iâ??m not kidding. Theyâ??re not coming soon, they are here. Just another little ol' thing I like to call... The future! uh, of grow lights that is.

Note that was a few years ago. I believe we are take off point for LEDs. My grow will be LED and T5s for veg.

nm â?? NanoMeters â?? This is a unit of measurement for the wavelength, or color of LED light output. 430 and 675 are the two ideal numbers (if there were such a thing) for veg and bloom respectively. Our visible range is from a little under 400 to a little over 700.

mcd - MilliCanDela - The unit of measurement most commonly used to describe the intensity of LED light. It measures light production at the source of the light. Compare this number when shopping for LEDs.

So how do you know when you've filled it enough? Do you change the water out every 5 - 7 days? Wouldn't want stuff living in the bucket... Is this the same principal as a flood table? Not sure.

Props for the nice pics.

Board Mods - How about a dedicated folder for LED discussion? Seems like LED is holding up one side of this table.

good call...a LED section would be nice! :thumbsup:

Dog~do your UFO's list percentage of 660nm diodes...and the degree of focus? way to go in trying LED's out:jointsmile:

There about 5 holes same height 1/2" below top bucket bottom.

I read a number of your threads last night. So i Joined. Good grows by the way. Today i came across this one dudes Scrog thread. with 1 400 hps doing very well. I'm conflicted.

1. Led wavelength AP (nm) 660/3000-3500k/460

10. photon flux density umol.m-2s-1 10.8(1.2m Height)

11.the irradiance W.m-2 2.30(1.2m Height)

12.install distance Meter 4.0m + 2.0m

13. install height Meter 2.5m + 1.5m

14. lighting area M2 20


Thats it I don't even know what some of it means. The height they want me to put the ufo is crazy i think. Check out the picture of this afternoon of the Ufo light hitting the plant. Ufo far away the light was red all over plant. Ufo up close light was much smaller.

Day 15 Veg and flower

thanks for the good words...i'm no scientist or even a botanist....i just enjoy growing good herb...i have "stumbled" into some good LED lighting and what you have is a tighyly clustered group of 1w LED's that need to be placed at the recommended height so as to get the advertised coverage...you lose coverage as you get closer and lose effectiveness as you move them away....i think they are great to veg with but as supplemental w/400 HPS in flower you should do pretty well! :thumbsup:

Ok I made a scrog for my veg room. I seen some guys thread that had the best scrog set up. I took his advice and started them early in training. All the plants under the screen got topped. So far i have had the plants 24 days. The two in flower are day 16.

Since i built the scrog in the veg room. When it comes time to flower I will just put in differnt lights going 12/12.

other ufo comes 4-26 I'll put that in the flower room and remove the 400 hps. I feel bad about it But OH WELL. I'll get over it. I think the ufos should be able to handle 2 plants. I hope. Maybe i'll add some cfl. maybe. Thanks for looking. Any coments or sugestions are welcome.
