ok so my other plant was a male now i got 4 babies growing after 4 other died this morning after being under my mh for only 3-4 hours. they all toppeled over and i tryed to save the 4 that look like they might survive by supporting them wit rocks. i was wondering if the mh is to strong at this age and if anyone thinks thses will survive.mind u that they were under A 40 watt flouro for about 5 days untill i swited under the mh

Sounds like it got too hot. The extra LIGHT from MH will not harm seedlings (I've started plants from seed under 400watt MH several times with no problems) but the extra HEAT would definitely cause problems if you don't ventilate properly. Do you have a thermometer? Was there a temperature change? As long as your plants are still green then there is chance for survival. Make sure there is a strong breeze blowing on them at all times.

Just a personal preferernce, but i like to start my seedlings under cfls as opposeed to my hid, Just to be sure i don't fry em ya know? I don't know for sure if all the light ouput by hid's is actually bad for seedlings, but the heat output definately is. Get u a thermometer/hygrometer($6 at walmart), to keep an eye on the temps and humidity at all times.

describe better your setup. how did they topple over under a 400. were they stretched? did you have a fan on them? were they sic? are you sure they are males? what is the age and the time cuz i am lost here, lol.

I want to here more of your tale.

I DO know for sure that the light output from a 400watt MH is NOT bad for seedlings. Don't forget that seedlings have grown under the most powerful light source in the world for thousands of years. There is not an MH anywhere that compares to the power of the sun. It is not the LIGHT that wilted your plants but the HEAT.

I agree . maybe u misinterpereted my last post? the reason for my using the cfl's isn't cuz the light, but the heat. Speaking of the power of the sun, wonder how many lumens it is lol.

Yea I wasn't trying to be a dick. After rereading my post I see it might have sounded that way. Sorry. But you did say you weren't SURE whether or not it would "fry" your plants. I'm just trying to assure any readers that MH won't damage seedlings as long as the heat is properly ventilated. I see many people hold off on using hid when they could be getting faster, more compact growth. I'm not saying to park a 1000watt six inches away, but no need to coddle them either:wink:

you said you had a fan on them if thats to close you might have wind burned them also to support seedlings dont use rocks an old trick i use it take straws from a fast food place cut them down to the size of your stem from the dirt to the first node split the straw down the side and wrap your stem for support

That's exactly right, 'properly ventilated' seems to get overlooked a lot nowdays. Like I said it's the heat that gets to em. What Im not sure of however, is this, say u had a hid light, mh or hps, say 400 watts worth, that u were able to keep 6inches away from a fresh sprout, would the 50,000-or so lumens blasting down on it bleach it at all, I'd think the plant would only use as much of light that it could, then the rest of the light would be basically wasted, less in like a sog setup but I'm talkin smaller game 2-5 plants. My hps that I bring in roughly halfway through veg is way too hot for me to try any kind of experiment like that, thats maily why i waait til they get bigger to fire it up, i don't want em to stretch out on me, and usin the cfl's in the begining has worked well giving me nice tight node spacing.

haha, you're going to laugh. I'm not at all looking down on fluoros to veg. I don't even use MH myself to veg. CFLs all the way. I keep all my hid lights in the flower room where they really count. But my first couple grows when I didn't have vegging plants and flowering plants going at the same time is when I used the MH for veg. This is also the reason I know the difference between veg growth with MH and veg growth for CFLs. They do grow faster under MH but 6 inches is too close for little sprouts even with 400 watt. I would say 12 inches minimum for new seedlings. So back to your other point. At 12 inches away, sure, a lot of that light is being wasted but the light that is hitting the plants is all getting used. I have air-cooled hoods in my flower room so I've seen what happens when a plant gets bleached from too much light instead of heat. Only way this happens is if the leaf is within like 4 inches of the actual bulb for DAYS. I'm of the opinion that seedlings have the same resistance to bleaching as an adult plant is really the point I want to get across. So yea if you put 400watts six inches away from brand new seedlings I think that is above their threshold but at 12 inches they will love it.

Idk if i mentioned it previously or not, but i do the same thing- veg with floro's for the most part, then kick on the hps for some juicy nugs:weed: I just put together my cool tube for my light, and i just happen to have 2 sprouts atm, seems like a good time to do some temp monitoring and see how they like it early. ;-)

the light is actually probably weak. your temp is the problem
