IS A 4.5w LED STRONG ENOUGH FOR SEEDLINGS?

@darcyraejoff Are you growing seedlings under it right now?

No they are in the corner of a tent. If this light isn't suitable, which seems to be the case, i will eventually get the t5 bars everyone has for seedlings.

I've seen those if you are talking about the long bar(s). I think i will have to get one before the next batch gets planted, it seems everybody who knows what they're doing uses the T5's for seedlings. On the subject of planting too deep I F'd the majority of the last seeds i did by burying them too far and i suspect drowning them with too much water too soon - also there is green funky stuff on some cubes. Ah well live and learn, thanks for the advice.

@darcyraejoff no problem. I used the cubes to start but for some reason when I did it the roots just weren’t taking to the soil. When I planted directly to soil and wrapped nice and tight. No idea why because a lot of people I know use the cubes.

Every manufacturer has different recommendations (should be online in the manual). You can use a par meter (best, but expensive) or a lux meter (much more affordable, but not as accurate).

On the other side, most cheap LEDs can be put pretty close to the plants. I would think within 10 -12 inches above seedlings. With cheap LEDs your main concern will be from heat (literally the heat from the light), stress not too much light.

@Living Gardening Wow that is much closer than I expected. This explains why I have multiple failures to sprout and also a couple which seem to have sprouted upside down (didn't even know that was a thing). Thanks muchly comrade, for all the articles, video tutorials etc there is nothing like a direct answer.
