New seedlings under a 400w MH

Feisty1UR · Jan 20, 2016

I have a problem, I've heard new seedlings need fresh air and they aren't getting any at the moment.

I'm growing indoors, and I was told damping off and mold rot can occur if no new air reaches your plants.

Am I doing everything right? The lights may be too high, or too low. I'm running a 18/6 light schedule.

The temps are 20 c around 40%-50% rH

These are pictures taken from yesterday,

I'll take a few more of where they are at now,

Get the dome off. No need for that

How do I keep the humidity high without it?

Also, the leaves are curling down... Any idea what causes that?

What's wrong with them? They don't look happy. One hasn't even sprouted yet :/

I was told it would be good as long as the lights are atleast 4ft away. I would use CFL's but thats like another £60

It will work with the 400watt

To me they look fine, they were just curled up in a seed an pushed up through the ground give em a few days

Cookie_rookie · Jan 20, 2016

Move the light Down slowly inch or two daily

Don't overwater em either that's the #1 plant killer for new growers

Good to hear! They've been growing since yesterday morning. I'll move the lights down tomorrow

I spray em regularly (Once every 5-6 hours), should I not do that?

They don't need that.

They're rooted, why would you foliar feed them?

Don't water them at all until your soil is dry, I mean dry. Get those roots working, don't worry about what's going on above the soil.

Cookie_rookie · Jan 20, 2016

Leave it up for a day or two

Then slowly move it down

And listen to superbaked
He's spot on

&
What kind of soil u use??

If the soil has any nutes, wait at least 2 weeks to add any aditanol nutes
And when u do start, start very very light 1/4 the strength recommend on bottle an slowly work ur way up

I'll stop spraying and just let them do their thing

What about the humidity? I've taken the dome off

DST · Jan 20, 2016

Listen to these guys. Leave them alone. They will grow great without constant attention. 400mh is fine and the distance is fine. These are just cotyledon leaves and are often twisted.

Feisty1UR · Jan 20, 2016

Lads? Anyone give me a few pointers for humidity?

DST · Jan 20, 2016

In what regards? To increase it...decrease it?

superbaked said to take the dome off, how can I raise the humidity

DST · Jan 20, 2016

A dehumidifier raises rh. Not sure you really need it. 40 to 50 is classed as normal room humidity. If it was way below 40 then I'd say to get concerned. If not then put a plate of water below the plant. Boil a kettle with the steam going into the tent....theres a load of ways you can get moisture increased. Unless your soul is drying out every day then don't bother.

Seedlings don't need the area to be 70%+ Humidity?
