Kermit, I think what that guy was referring to with "soilless" is rockwool or possibly rapid rooters... Although, they are made from compost. He's absolutely right about pH fluctuations with distilled water. Distilled water is what you want to ADD additives to, but not using it unaltered unless you're flushing - as I was using it pure, only attempting to pH it, and not adding nutrients to it. Wondering why after a couple days in the seedlings would mysteriously stop growing. Well, I have clean pH'd distilled water in there, the temp and humidity is in range and I have plenty light and they grow up to day 5 then stop, mmmm...?
So then I change my ways, come on here and ask about a the leaves bending down, not curling, not turning crisp/yellowing or dying, they're green and healthy and growing daily and I end up getting a bunch of smartass know-it-all's telling me I'm doing it wrong with the nutrients, lol. Laugh out loud!!! I'm sure that guy who pulled 28oz out of a 3x2 scrog in 30/55 days was doing it wrong by feeding his seedling after the 3rd day and even jacking it up to 900ppm after the 8th day when he moved it to the bubbler. LOL. Any more advice about feeding a seedling? Or are you going to say that you aren't feeding it with your tap water? LOL. get the hell out of here. You're seedlings will develop nice healthy teeth with the fluoride.

Honestly, I don't give a rats ass what these guys say about not feeding. They can use a bullhorn to proclaim this misinformation from atop the highest mountain and I'd still keep feeding, because regardless what they say, they're feeding their seedlings with what is in their tap water. It's pure ignorance.

"Some people use distilled water for household
aquariums because it lacks the chemicals found in
tap water supplies. It is important to supplement distilled water when using it for
fishkeeping; it is too pure to sustain proper chemistry to support an aquarium ecosystem."
"Drinking water sources available to North Americans may contain high levels of
Ca[SUP]2+[/SUP],
Mg[SUP]2+[/SUP], and
Na[SUP]+[/SUP] and may provide clinically important portions of the recommended dietary intake of these minerals. Physicians should encourage patients to check the mineral content of their drinking water, whether tap or bottled, and choose water most appropriate for their needs."
Enjoy!
