All I have is a 1000W MH to pop the seeds.I've germinated them and they will be placed in the grow bags today.I'm thinking 3-4 feet above soil should be OK.I'll test heat with the back of my hand ofcourse and raise it if needed.But I don't want them to stretch either.
Any suggestions. ;)
I used CFL for the first two - three days!:)
Worked fine for me!:D
j dogg, I read somewhere on here that a guy sprouted seeds with a 1000... he said the light was 5 feet away.. 3 feet seems to close to me.. your biggest concern should be that the 1000 watter will dry out your soil and kill your seedlings.. keep a close EYE... be obsessive..keep the soil moist around the tap root(sprout). A light like that can dry out a seedling in minutes..
word!
: )
3-4 feet should be fine. Anything higher may cause plant to stretch and become weak. It would be wise to have a small fan, on low, to move the warm air around. Circulation, drainage, no over watering, no over feeding is the key. Lucky for me and you that there are plenty of good cannabis related websites to guide us along.
dai*ma :D
I vote for 4-5 feet like knowmy said...I've used 250 at a foot and 400 at 18-24 with fan, but if it was my Horti...I would say at least 4 feet/+...Imho
I got it at about 3 feet and I think it will be fine.Can't feel the heat with the back of my hand down by the soil.So I think it should be fine.I check on them all day so they'll be takin care of as far as watering enough,stretching, and air circulation.I know what I'm doing ,I've just never popped seedlings with a 1000w light,but thats all I have.Right now the weather is cold so the temp is about 70 with the light on in the room with no ciculation.
I turn the AC fan on for 10 minutes about 4 times a day to bring in fresh air from outside.I'd leave it on all the time if it was warmer outside.At night I keep the heater at 70.During the day I run the house fan for 10 minute 4 times a day.and constant fans running in the room for air movment.
I vote for picking up some cool white fluorescents. That's too much light for seedlings.
I've grown seedlings in direct sunlight...are you saying they can handle that but not a 1000 MH light 3-4 feet above the soil.
Even after being on 24/7 for a couple days it's still only about 73 in the room...It really doesn't seem to bad or to hot or too bright...but I could be wrong...I know it's probably more difficult but it's not impossible is it?
use a piece of tinted glass
dont you have any other lights, I mean it seems to be okay but a waste of electricity. Why bother using such a powerful light on seedlings when its gonna cost you a shit load of money for no more positive effects maybe even negative
