Hey there,

I'm sure there has been a billion questions about these LED's already. I'm sorry if any of my questions have been asked before. I'll continue searching, but I'm making this post so I can hear some advice, feedback, etc.

The reason I'm debating these LED's is, well.. they just look plain cool. I have always been a HID grower (for flower), and I like to try new things out. I like to give everything a try at least once. As of right now, I have not made the 100% decision to get an LED for this little cab I'll be building, but I'm strongly considering it.

A little background, I've been a cab grower for quite a long time now. I have 2 cabinets. A flower cab with a 400w cooltube HPS, and a veg cab covered with floro tubes. My other flower cab is a bit larger, and I'm interested in building a new cab just for fun. I was thinking of looking at alternative growing souces. I'll be running the 400w cooltube also, but I would like another small flower cab for select strains. Heck.. I might use it as a breeding cabinet. Keep the pollen away from the main flowering cab. The rooms would be completely seperate of course to avoid cross contamination.

Anyway, here are a few questions I have. Please excuse me if they have been asked a million times, I'm just trying to keep all my questions in one thread. I'll edit my post if I find the answer to any of these questions.

1. Can you successfully veg with LED's? I'm sure you could, but I wanted a little feedback on someones veg experience under LED's. I have a veg cab to make up for this.

2. Heat? I believe I read already that LED's produce very little heat. I can keep the temps between 78-82 F, so having temps be to low is not an issue.

3. Noise? I believe I read our LED-Lady tell someone else its around 45 db. I believe that is perfect for a cab, considering I have been running a couple 265 cfm exhaust fans.

4. Duration? How long are these lights good for? I believe I replaced a HID bulb after every 3-4ish flowers.

5. Will exhaust effect this system negatively? Will it lower the temps to much? I need to exhaust into a scrubber to keep that smell down. Of course I could use a smaller fan. Temps on average are 78-82 F. I believe I read 80 is best for this system?

6. Which light do you recommend for this setup?

36'' tall
17'' deep
24'' wide

I believe I'll just be running a SCROG setup. I'd like to get some good penetration down into that screen.

Some good questions. I am also starting up a new cab about the same size as yours 30Wx24Dx32H. I have been doing some reading on led grows and am on the verge of getting me one. I will be splitting my box in half with the front half a veg chamber and back half for flowering. probably just 3 plants in a SCROG setup as u mentioned. So Ill be watching for what answers you get!

TommytheCat: first of all, love that nick, Les rules

I'll tackle all this, willingly...let's go!

1. Can you successfully veg with LED's? I'm sure you could, but I wanted a little feedback on someones veg experience under LED's. I have a veg cab to make up for this.

Oh HELL yes.... You will get tighter internode spacing and incredibly dense vegetative growth. I promise. I've not failed to have stout dense bushes with my LED grows.

2. Heat? I believe I read already that LED's produce very little heat. I can keep the temps between 78-82 F, so having temps be to low is not an issue.

What heat? In my closed cab, with a 126W unit, I rarely went above 85F, and actually the range you are capable of maintaining (perhaps a couple of degrees higher) is perfect for LED growing.

3. Noise? I believe I read our LED-Lady tell someone else its around 45 db. I believe that is perfect for a cab, considering I have been running a couple 265 cfm exhaust fans.

So quiet you can barely hear them. I snore much louder.

5. Will exhaust effect this system negatively? Will it lower the temps to much? I need to exhaust into a scrubber to keep that smell down. Of course I could use a smaller fan. Temps on average are 78-82 F. I believe I read 80 is best for this system?

80 to 82F is good. If you need to vent/scrub then do so. Try your best to maintain that temperature.

6. Which light do you recommend for this setup?

36'' tall
17'' deep
24'' wide

If venting and being able to maintain temperatures aren't an issue, I'd go with a 126W unit, especially if you plan on stuffing multiple plants under a scrog.

All this said, you will surely have to tweak your growing techniques to maximize yields, however, scrogging and maintaining the 80-83F range is a great start. Hope this helped!
