Hey Princess,
Let me see if I can answer your questions.
That looks like a mogul socket. Where did you get it? Does it belong to another lamp kit?
There are 3 possible types of light fixtures for bulbs:
1) Edison Screw: These are the usual household sockets. They are also the ones you use for CFL's. It uses standard 120V power.
2) Mogul Socket: This is a larger type socket. It still uses 120V. No transformer is required
3) HID Ballast: This not only has a larger socket, but includes a transformer to increase the voltage for the HID bulbs (not sure what that voltage is - doesn't really matter). Depending on the wattage, the transformer may be in the overhead ballast or it may come as a separate unit.
For you setup, it looks like 1) and 2) are your best bets. The socket you showed would work with a 100W HPS bulb. What are the wattages of the MH bulbs that you have? If they're 100W, then a mogul socket would likely work for them. If they're more than 100W, I would think you would have to go with a ballast and transformer. Not positive. It really depends on the bulb manufacturer, I guess.
It's almost impossible to get light burn from CFL's unless you're very close, say less than 2". If your plant is that close, then move it away a little. 3" or 4" would be fine. If it's not really that close, then it would be nutrient burn.
I don't think you've fertilized your plant yet, have you? The soil you're using doesn't seem to have its own nutrients and if you haven't been using them, then I guess it can't be nutrient burn, but sure looks like it.
At this stage, it's nothing serious. I burned the edges of the last seedling I grew and she turned out fine!

It is a mogul socket but i wasn't sure if it was compatible because it says usable up to 1000 watts and my metal halides are all 175 and they're from GE electronics.
Im not feeding any nutes yet so i wasn't sure what the mildly burned edges are from. Distance from the light is about 4.5" and the wattage is an "equivalence to"(i.e. equivalence to 75 watt incandescent) bulb so its hard to say. hopefully its nothing.

Yeah, I wouldn't worry about it, Princess.
Just keep an eye on it. If it doesn't get any worse, you'll be fine.

I've been reading about HPS lamps. I thought some of them might work with 120V and a plain Mogul socket.
Not so! They ALL require a ballast (transformer and capacitor).

thank you that should really help with my problem, however a new emergency has appeared. I think i know whats causing the yellow spots.
roots are coming through the bottom of the solo cup! in every little drainage slit theres a root coming out. Is it emergency transplant time or is it ok?

if its not light burn or nutrient burn could it possibly be a pH problem? (water OR soil)
like every one else was saying it doesn't appear to be that big of a problem right now but just keep an eye on it.
EDIT: we musta posted at the same time cuz i just saw your photo
NICE ROOTS! i would consider transplanting soon. you dont want the roots to start coming out all those holes then it will be a pain in your ass to transplant. id do it with in a day or 2.

Haha must have! I was checking on her to see if the spots were gone but there getting worse. Could this be because of the roots? if so I may transplant now. Don't want anymore damage to be done.

Yes, Princess,
Take her to the ER now and perform a cupectomy. STAT!
Use a pair of scissors and carefully cut the cup away. It's best to let the cup dry out some. If it's fairly damp, punch a bunch (hey, that rhymes!) of holes in the sides and bottom and keep in a warm dry place until it dries.
It's so much easier to transplant when the soil is dry. That way the whole root ball comes out cleanly. Otherwise, you'll have a muddy mess. While this isn't a big deal if you're careful, it's better not to stress the seedling any more than necessary.

Start scrubbing, Dr. Grey!

Alright! Its pretty dry around the edges, mildly moist on the inside. I pinched the sides and it looks like i can just cut it open and pop it right out! Thanks for all the help. Those roots terrified me. They look a little... um Tangled? I don't really know. The pics show two long ones tangling together and some small ones stuck in the slit. A little unraveling wont hurt the roots right?

Serious roots. That had to be the early onset of being root bound. It was excruciatingly hard trying to cut around them.
I regret to inform you that one simply could not be untangled. The result? Severed.
She is now happy in her 1 gallon container. hopefully not to much damage was done. my next investment? Box cutters. Scissors are just impossible.
Hey there Princess!!
I can see you are a determined chica, keep up the work =)!
Hope you don't mind me tagging along!

Hey Princess,
Whenever you transplant, you will see the roots as a tangled mess. They grow so long that they start wrapping around the pot. No big deal.
And don't worry about messing around with the roots. Some growers cut the extra growth off the roots. You can use a knife or a pair of scissors to cut them if you have to.
She looks quite pleased with her new digs and I don't think she'll miss a beat growing up.

Thanks ggrant. I wasn't sure if she'd be ok but she looks find. No real growth changes for a while. Could it be stress from being locked in a cup for so long?
I've only been feeding her purified bottle water at room temperature i'm thinking of starting veg. Today would Be week 3 since seedling, is that to early to veg her?
If so then i was thinking, to decrease stress every day this week starting today, give her one dark hour and add on until next week when shes four weeks and doing 18/ 6.

thats not a bad idea to stagger the light schedule till you get to 18/6. Dont be discouraged if your plant isnt exploding in its first few weeks. Also try getting more light in your grow area will help speed up the process

My next investment is definitely going to be another light fixture and nutes.
So if my plan is correct then today i should do 23/1
tomorrow 22/2
and so on. Then maybe wait a week, get nutes and start feeding, then another light fixture.

You can buy a 100W HPS for about $125. I'm sure if you shop around, you can find one for a better price. It doesn't require a ballast or anything. It has a mogul socket, which is wider than a regular bulb socket. It doesn't have a transformer, nor does it need one. It uses 120V and plugs into a regular outlet, so it's really no different from using any other kind of light.
On further research into this I did NOT see any HPS that DOES NOT require a ballast...All the 100w HPS lights I seen DID require a ballast...it would be dangerous trying to ignite a HPS bulb with a ballast...
Of course, HPS lamps give off lots of heat, so you have to keep your plants about 12" away from the light.
Keeping a 100w hps 12" from the plant would render it pretty useless...it's weak to begin with...
By the way, HPS bulbs are twice as efficient as CFL bulbs! Not sure of the size you're using. I use 25W CFL bulbs in my reflectors. A 100W HPS bulb has the luminous energy of eight 25W CFL bulbs!
Also upon further research it's more like 3.75 CFL bulbs... All together a 100w hps is very ineffecient and IMO a waste

I even included a link that explained all about ballasts.
But since you brought it up, let me reiterate:
Have you ever wondered why the base of a CFL is so large? It contains a ballast inside of it! Since the wattage is so small, the ballast can be miniaturized to fit inside the housing. That's why the bulbs are so cool but the housing is so hot (heat from the internal transformer!)
HighFlyin5 said:
Oh yeah! I dare you to lie under one for an hour 12" away. I'll bet you'll have the worst sunburn of your life! I use a 400W HPS so I was trying to give a safe distance to use - I may have been overly conservative. Have you ever seen a 100W HPS in action? I have and believe me, you do not want to get too close to its bulb!
HighFlyin5 said:
Bullshit!
I admit when I wrote that I was thinking of my own HPS which IS twice as efficient as a 25W CFL!
A 100W CFL is STILL more efficient than a 25W CFL, though not twice as efficient, say more like 30%, rendering it equivalent to about 5 25W CFL bulbs, NOT 3.75 bulbs!
And I'm not sure what bulbs you use, but the quality of a MH or HPS bulb feels more like sunlight than a cold CFL. I know it's subjective, but I use both HID and CFL bulbs and I can sense the difference and so can the plants, in my opinion! (Let's not debate this. I said it was subjective.)
So ... a 100W HPS is not a total waste. I was thinking of buying one to use as a staging area for plants that would move out of my veg space before they entered the flowering room (which has a 400W HPS bulb which IS the equivalent of eight 25W CFLs).
I appreciate you're only trying to help, HighFlyin5, but please get your facts correct before you post. And add a link or copy the information from a reliable source!
Moving On!

You'll see dramatic growth once you she gets some nitrogen.
