can i use a 400w hortilux super HPS EN conversion lamp which has 25% more blue light than regular HPS- on my seedlings? anyone know if this will dry out my seedling? have any info- my seedling is taking a while to shake off the seed shell- I know I shouldnt touch it but it popped its head out of the soil two days ago. I'm keeping it 2-1/2feet away from light. This is the only type of light source I have- except for my regular HPS bulb- for the flowering stage.
Should be fine, just keep your lights distance the way you have it for the first couple weeks. Good luck!
now that seedling is growing really slow- I actually have the lamp at 3-1/2 feet awaynow- but its a 400w bulb. I have 2 other seedlings about a week old and they look weird- the cetalydons or whatever are looking healthy but the stems are 2 inches and just little specs of the 2nd leaves to come- and they're curling a bit. I have an AC running- so its not the heat- should I run my humidifier? or is it maybe too small in my closet for a 400W bulb?- the closet is about two feet in depth and 4 ft in width and 9 feet in height please anyone
