How far should i keep my 1000w MH lights above my new clones?
How far should i keep my 1000w MH lights above my new clones?
New clones must be treated tenderly, they probably don't even want to be under such a lamp for the first week.
here is the set up
any help is needed
Looks great, I'd love to have that, but be careful with the clones, they're all stressed out and weak at the moment.
but how far is far faithlessxxxx?
Measure the temp at the plants, and keep it not more than 30C at the most, try to stay around 25C, distance probably between 30 - 40cm.
its around 77f at all times due to air circulation no matter how far the lights are
Great! usually the recommendation is around 30-40cm, but I wouldn't dare do that until maybe the second week of the clones lives.
I've never cloned, though I'm about to, but have read up loads on it.
Maybe someone who does it will help you more.
They seem to be at a pretty reasonable height from the pics.
Good luck, and I'm mighty jealous of your room
look at the problems w/ the plants im having
Thats burns, either from the lamp or from too much nutrients (too early).
I'd guess you're giving them too much power, light or nutes, too early.
On the other hand, clones always look weak the first weak apparently.
i fed them once with npk ratio @ 5:5:5 half of the amount it set at the bottle.
Yes, but your soil has ferts, doesn't it? Takes 3-4 weeks for the ferts in soil to get used up.
You're stressing them, treat them like a patient with a cold, no exercise, no hot curries, just soft lights and water.
Check that link for nute or heat burns, you have one or maybe both.
Otherwise they're looking nice to me
thanks faithlessxxx! now all i do is wait, i will add you to my buddylist and keep you posted, how are your plants doing?
I've got one approaching flowering, she's doing great (my avatar), sh'es 42cm of thick bush, but I've tied her down to 24cm to train her side branches up, so that I now have 8 roughly equal tops (called LST).
I'm going to cover one branch tonite with blasck paper to speed things up. If she's a girl, which if course she is, I'm cloning her ass and flowering and smoking her poor remains - if she's not, which she is, I have 6 seedlings just a few weeks behind her, and once I find that elusive female, I'll be cloning 24/7.
Some of us, unlike you, have to start from seeds

Maybe some people would suggest covering them with a plastic bag for humidity, but I'll leave that to someone more in the know.
ive been growing from seeds for the last 4 years outdoor, this my first clone and indoor experiment.
I have had clones under a 1000 watt HPS and they came out 100%. You just have to keep the HPS very high above them. I'd say a good five feet. Just an estimate, but you get the picture. It is a terrible waste of electricity though but is acceptable if you have other plants at different stages, but that is obvious and you probably didn't need to be told that. Anyways, good luck!

You'll be better off listening to TGT whos actually done what you're doing, of course. But I'm curious, 5 feet for a 1 000HPS? Is that correct? Why would that be better if the temp at the plants is 75 at 20"?
I am getting different answers from everyone. i think my plants are still in shock either from the transplant or from the nutrient/heat burn, they havent been growing since sat. when i got them. right now they are about 3 ft above my plants.
Well, one thing I feel I can assure you, is that you should keep a low profile on them for the next week or so, 5 foot probably is a good recommendation at this point til they come out of shock anyway, giving you time to assess some more answers.
I think noone will disagree that they need soft light and a minimum of nutes until they perk up.
Doing the opposite will be like sending a survivor from a car crash down to the gym for a workout.
The reason I say 5 feet is because a 1000 watt HPS is far too much light for the little guys (girls hopefully) to handle. Clones need a soft light and by placing them at 5 feet it will insure their not getting too much light. I don't think the temperature is that much of a concern as long it is well in the limits of regular growth. I have noticed clones will root fine in 20 degree celcius temperatures or 28 degree's, but the later might be a little faster. Sorry for the Celcius, I don't understand Farenheight as well.
Also something that I have found that speeds up root development is to let the rockwool go through a slightly dry stage before watering again. Not dry, but fairly light and a hydro dome should be used so that the leaves can also soak up some water through humidity. I find this dry rockwool stage supplies more oxygen to stem and stimulates calis build up that is the first stages of root development.
Believe it or not I have found that a regular incandecent bulb will root clones just fine. Some people will disagree but I have done it numerous times and have had 100% success rates. I didn't think it would work too well either but I had no other light available the first time I did it so I thought I would try it out. Now that I know more I believe it is because of the high red light spectrum that is emmited from an incandescent.
If your clones are in a hydro dome you have to be careful not to pull the lid off quickly as a draft or a fast change in temperature will droop your clones almost right before your eyes. One thing I would like to know is, is your clone root a constant temp? Even an opening door can cause a slight breeze and that fast change can shock the plants. They usually come back two or three days later as long as the temp stays constant.
Well, enough blabbering. I hope some of this info can help. Good luck and let usa know how she goes.
dude till they take good root youd be better off with a couple of cfls
Hey we started at the same time, when did you plant around 9/30?
First of all totally relax the plants are just fine
When you first transplant the plants will first of all be in shock, nothing to severe but secondly;
During the last week and next week your plants are going to be growing roots, and then some more roots As long as it is getting enough " food " from light it wont show off with big sturdy leaves and new growth. It will look wilted but yet strong, some slight curling I noticed.
The burn would probably be nutes I really doubt from the light, it could just be nothing. I would go really really slow on nutes add them from 20% strength on up to where you feel they are happy , all strain take different amounts of nutes just talk to your plants they willl tell you if happy.
While they are rooting you would want the light like 40 inches away, after they have rooted then you can put them as close as you can hold your hand for a minute without it feeling uncomfortable.
so even like 20 inches if good fans and air flow , just hold your hand there for 60 seconds and see if you would want that amount of heat for 18 hours.
