hello all!
i have 2 seedling thats few days old, they alrdy sprouted from the soil
i have only 400w hps light with cooltube and air controll
my grow room dimensions are hight:150cm length:75cm deep:55cm
i want to put them inside the closet now, so my question is
how far should i put the 400w hps light above my sprouted seedlings??
If you only have two seedlings id just go grab a couple 6500k 26w cfls. til they get a little bigger. Work up to that 400 plus theres no need to put extra use on that bulb until its needed. Cfls are way cheaper than a replacement bulb for that 400
If you don't do what pushit says....
90cm should be fine... You don't want too bright of a light directly on top of them at such a young age...
However I agree with pushit, would be better to start them off light....:thumbsup:

hey pushit, i just dont have the place nor money to get the cfl's now
thats why i asked how far i should put them :) ty for your answer tough
and cangroit, 90cm sould be fine? isnt it too far?
Go find a double socket hood (pet store fish tank or terrarium tops work great $20-$30) come with built in reflectors. I have the EXO-Terra hoods
Then get a couple 55W 6500k CFL loopy lights..
EDIT :whoop sorry just saw your last post..
i agree with pushit get flouros. id prefer a couple of two foot flouros, the spread is much better for two seedlings and you can put them an inch away so they dont stretch so much.Quote:

so if i put them under flouros how long till i have to move them under hps?
also a thought
in the nature, they are getting full sunlight even as seedlings, dosnt the flouros make the plant weaker?
they don't call them High Intensity Discharge lamps for fun.... 90cm would be too far for a full blown plant in flower but a seedling needs to reach for the light and grow some leaves to catch it before it can take the intensity. Start at 90cm. If they look like they are stretching, lower it to 80cm. As it grows, close the gap between the lamp and the plant tops, but wait until you have at least 4-5 internodes before getting it as close as 40-50cm. Once in flower, you can get it as close as 30-40cm, as long as temp permits....Quote:

If you cant afford a couple cfls and a clamp light finishing these plants is gonna be hard. Im not trying to be a dick Im just a realist. What if you run into mold or insect problems? What if your plants need extra nutes? What if the temps are too hot? Its always better to try and cover all the "what ifs" before you start your grow or you will find yourself in a bind. Trust me i found out the hard way. I thought i could throw a couple seeds under some cfls and in 3 or 4 months id have some bud. The list of what i ended up needing got to be pretty big during that grow. Once again im not trying to put you down im just adding my 2 cents.
Haha. I'm right there with u pushit. I thought a light and some dirt would be all I needed. Boy was I wrong. But on the other hand, learning the hard way is learning. Won't forget what u did wrong after a plant hermies.
thanks for your replies, and dont wry pushit i know ur only trying to help :)
i talked with the store that sold me the equipment they said they can change my lamp+the power supply thingy for 2 250w hps, one for vege grow and one for flowering
i hope the 250w is a better solution
what u guys think?
250 is fine, but you don't use two sodium with one for veg and the other for flower. They're both for flower, but you can use one for a plant when it's small and add the other one later. It's metal halide that is typically used for veg.
I wouldn't trade a 400w for a 250w.... Are they going to give you 2 - 250w lamps that you can run at the same time or just 1 - 250w lamp with 2 bulbs, 1bulb for veg and 1bulb for flower???Quote:

Double fixtures are inexpensive and so are CFL bulbs....well worth the small investment. No, the CFL's will not slow growth, if anything they help because of their low heat transfer and ability to get plants to practically touch the bulb before over stressing....

I agree with CanGroIt on the 400. Stick with that. You can still use it for veg then for flower. Mh is more preferred for veg but hps will do the job.:thumbsup: As for the price on a cfl setup for seedlings.... 2 bulbs for 7 bucks, clamplight around 7 bucks, Y for both bulbs 2.50. Less than 20 bucks for the setup and you can use that in a little box or something and place anywhere in your place. Or you can just put them over the seedlings and run the lights 24 (that way any other light wont interrupt their dark time) til they get big enough for that 400. Thats just what i have done in the past. You can triple that it id be around the same price as a replacement bulb for that 400. Just something to think about. Hope that helps.
cfl's are flouros also. its just the spread of light is different. this kind of light is sufficient for seedlings and clones. once their canopies expand you need higher intensity light. also as pushit said know this, if you want the best it will cost a little. reward is very little cost per ounce, once the initial setup is complete. two plants under a 400 cant get very tall.Quote:

Flouros are good idea as they cool temp-wise and cheap but if you store if willing to switch you one light for two, going with two 250s might serve you better in the long run. If not, then the stronger 400 and a flouro or two would be smart.
Im not positive but i think he meant to say one 250 with two bulbs (MH and HPS). So its just one 250 i think. But if hes talking about 2 separate units then thats the way to go. 500w is better than 400 in my book any day haha.Quote:

If not, then he needs one hps ballast and one mh ballast. So that's why I thought he was saying he'd get the 400 switched for the two 250s.
Cool, CanGroIt asked that question and has yet to be answered. It could be either or and until rbush replies we will never know haha. Nothing to lose sleep over.Quote:
