Straight Rootz OK for seedling?

My latest scheme is to use straight Rootz Organic (not SS) in a 1 gal nursery pot. Dig a center hole and fill with Promix Starter. Very mild stuff.

Then plop the cracked seed into that little promix sump. In a week or so the seedling might grow through the Promix and reach that Rootz. Is there a risk of the Rootz burning the seedling? I wouldn't think so but before I do this I thought I had better ask.

Thanks.

All the TGA gear I've run did great in straight Roots. I'm under 1kw's though, and I have heard from other people that if you're under floro's the Roots can be a bit hot for babies.

Lighting has absolutely nothing to do with soil. If it works well for seedlings under one type of light it will work well under any light.

I've asked around on other forums as well and all say Rootz is fine for seeds / seedlings. Thanks all for the input.

Hah. Then why will a plant grown in a given amount of soil deplete nutrient levels much faster under a HID lighting than under floro's? And why would plants grown with liquid ferts need a higher EC level under HID than under floro's when that EC would burn the shit out of them under T5's? Speaking from experience here, btw.

Because higher watt HID lights deliver more energy to the plants therefore causing faster growth and more demand for nutrients. The question was about starting seedlings in plain potting soil and young seedlings are not fertilized, and he is clearly growing organic anyway so your comments about liquid fertilizer are irrelevant to the subject.

Correct, and if there are more nutrients present than can be metabolized by the plant because of less light energy, the plant will burn regardless of hydro or organic. Throw two clones in pure super soil, one under T5's and one under 1kw MH and see which one survives. That's my point. If you don't have enough light for the plant to use the nutrients available, the plant will burn.

And a buddy of mine did in fact burn seedlings with Roots Organic. He veg's under fluorescent light. I pop seeds directly in Roots but I do it under 1kw's and mine don't burn. I'm just trying to illustrate the point that type of lighting and, more importantly, intensity of lighting has a great deal to do with how hot of soil you should use or how strong of a liquid fertigation you should use. Again, hydro v. organic is irrelevant here.

Not trying to argue, brother. Have a good day. :eyesmoke:

I have seedlings three days old growing in Rootz with 600W HPS (Blue Hort). They are about 2" tall and looking really good. There's a LOT of light, so I can't comment on the survivability with fluoros. When I asked around I found very few warnings from folks. Not saying there is a risk, only that most guys felt there was no risk

Started Literally thousands of seeds under flos in Roots Soil
Prefer a big lamp for fast not stretch type growth
There is some sound reasoning to the logic that more light would use/need more food but
personally I have started more seeds than I can count under flos in Roots soil.

I agree. But babies have burned up in Roots before. I just thought it was worth mentioning. Genetics could also play a role here. TGA's lines are bred to take the heat, IME.

loved roots for seedlings but it seems a little less nutrient rich than ocean forest, i say watch for plants losing vigor after 2 weeks then start nutes. i thought the ph was off in my roots but after i transplanted to 3 gallons the perked up and are doin awesome.

also started mine under T5 HO flouros...

After 10 days in Roots:
View attachment 1770979

Growing PlushBerry. Growing in straight Rootz. 600W HPS Blue hort. Temps at 78F. Seems if it was burn I would have seen this when they were 1 day old. No sign of this until day 10.

I wondered about maybe over-watering. Also, only 1 of 6 plants is doing this. Maybe the roots came across a large nute particle causing a bit of burn. Or a bit of over-watering
