Hi.. So what Light should i use for the very young seedlings(1week or so) cause i only have the 1000w spectrum Led Light and i think its too much watts for them.. Maybe i need another to first weeks, any advice?
I used a 60w cfl @ 2-3†for a week or 10 days and then ts 1000 @ 36-40†on 50% power until third node grew out and started to lower light and increase power. Now at about 24†and 100% power and looking good.
I like to use T5s for the first 2wks above dirt. You can get them down close without hurting young sprouts and they put off the right amount of heat. You don’t need the big 6 or 8 T5 lights, 2-4 is perfect and you can sprout a bunch of seeds or clones under them.
I use 400w and 600w MH for seedlings sometimes. When you have a bright light but don't have a dimmer switch you just keep them a bit further away so you don't burn them.
Just put your light higher to start, like FunkyButtLovin said above. You should be fine. They're not a true 1000W light so they usually aren't as strong as you would think.
I like using the lower wattage (60w) cfl in that early stage too. You can keep it close enough to give the seedling heat but not worry about light burn / toxicity. Plus they come with that directional hood at the hardware store, no wasted light.
I used a 4-ft single strip LED shop light from rural King about 8 to 10 inches away do it every time on my clones all the way until they're ready to veg great results perfect temperature. Not strong enough for veg cycle but maybe get you to that point. Less than 20 bucks
Hey @Xena
how old/tall are yours now they’re under the light at 24†and 100% please?
I’ve just put my 19 days old under an SF1000 at 24†70% and I’m worried it may be too much for it
Thanks 🙂
Sorry, one more question, have you started giving nutes yet? I’ve heard you don’t need to in soil at this stage, but always open to advice/ideas ðŸ˜
I use two 42 watt cfl bulbs per seedling and they seem to thrive. A desklamp With a splitter socket and two “daylight†bulbs about 2-3 inches above works very well. Economical too.
I’m not....I started mine in solos in just plain potting soil and I transplanted into my 3gal smart pots right after I moved from CFLs and I think the soil I’m using is pretty “hotâ€, I think it actually burnt them a little at first so as long as they’re growing good and looking good they’re getting nothing but 6.4-6.8 water.
