Invisible Sun ISH3R and seedlings

Post by Tictok » Sat Oct 19, 2019 1:25 pm

Hi All

First proper post after the introduction post.

I have an ISH3R in a 60 x 60 x 150 tent.

The light is currently around 80cm above a couple of photoperiod seedlings and I have the dimmer turned down to just off the lowest setting.

Would anyone have any experience if this light and Seedlings? I k iw ideally I should have cfls but I'm hoping I can use the ish3r instead.

One seedling started to stretch (sunset sherbet) while the other NL isn't stretching much at all.

I appreciate the challenge of having two different strains but could anyone advise what wattage the ISH 3R puts out at the lower settings and what setting/height is ok for seedlings?

Additionaly, when they get into Veg, can I just crank it up to full or is that the reserve of the flowering stage?

Any advice would be much appreciated

All the best

I have seen GMO, Keeno and Bulls have issues even on lowest with invis panels on seedlings - I personally didnt have issues - possibly lucky and I dont grow in a tent so maybe just less light. It sounds a lot of light for a 60x60 - what watts is the light drawing at lowest?
ohh god, inlaws arrived.... sorry better go :(
Also I wouldnt use full whack till flower. youd be amazed how little you need on veg.

Many thanks Nanook, I'll get it in the lowest setting and hope for the best. I'll have to pick up one of those wattage meters for the plug so I can work it out.

Good luck with the I laws, always a joy (we'll mine are anyway!).

One just commented on my dog. There's quite an atmosphere here after telling her the dog means more to me than her and she can happily fuck off 😂😂😂

Ah, those special family relationships, can't live with them, can't kill them! .
My mother in law is a full on narcissist, I've not plucked up the courage to tell her to fuck off yet! It will happen though.

Pmfsl, mines had it a few times tbh but as much as I hate to admit it we are quite similar that way.

Here's a small update;

I turned down the ISH3R to its lowest setting and both the photo Seedlings starting performing much better, the hanging height is 80cm. I also have 2 x 7.5ltr airpots containing sprouted auto seeds that had not broke surface yet (auto brooklyn sunrise from Dutch Passion).

Now these pots are a good six inches closer to the light and today when I found two baby shoots, I noticed that the most developed one had signs of light stress, I think. The edges seemed a little brown. I'm not sure how to upload photos here without them containing unwanted meta data.

So the plan will be to fire up my old trusty Kingbo 300w (120w actual) and stick the baby autos in the second 60x60 tent until they are big enough to take the light.

While this sounds negative, I have really high hopes for the ISH3R. If I'm on the lowest setting the that gives me loads of room to play with come flower time. To be fair I knew this was going to be a tad strong for seedlings, but it's been fun working it out.

Thinking about it, I had the photos still in a propagator with the lid on so perhaps this diffused the light a little?

Onwards and upwards..

Slight change of plan, I've put two halves of a 5ltre water bottle over the new shoots, sprayed some water inside and will see how this fairs. It might diffuse the light a little. Time will tell.

Sorry missed this - the site scrubs meta data mate. Part of security but if your worried theres loads of programs to do it :)
I would like to see pics as what your describing could be feed or light.

Thanks Nanook, good to know. I'm hoping it's not feed as they've been sprouted in Clover multipurpose, which is supposed to be fine for seeds/Seedlings.

Here's some pics;
first the auto brooklyn sunrise that's just popped her head out;

This is the NL photo, 1 week and 1 day old;

Then the Sunset Sherbet again, 1 week and 1 day;

This is the current set up (bearing in mind I have another 60x60 tent/light etc that I can use if it gets crowded) ;

I'm now thinking is that NL showing signs of light stress?

are you spraying them with the lights on? I never follier feed tbh but some say im wrong.
I think your doing it right - the lights are a bit too powerful for seedlings according to many so just as far as you can away and turned right down is all you can do :)

I am, but the baby in the first pic looked like this before any spraying. I use a mild solution with some seaweed extract. At this stage I also spray the walls of the tent to keep the humidity up.

Do you think it's just down to strain/pheno that the northern lights is so much shorter than the sunset sherbet?

What one do you think have light stress Tiktok? I don't think that either do tbf. Just out of curiosity, what's the temp at the bottom of your tent where those seedlings are?

Could be strain, could just be seeds - I wouldnt worry. My point re spraying was people tend to do it lights off to save scorching them with the lights :)

Forgot to say it could be the seaweed you're spraying thats making one stretch. Seaweed contains Gibberellins.

Temps are ok, around 21c, they max out at around 25 and the lowest has been 18 in the night which is a tad low I think.

I thought the babies might have had light stress, but they only popped up this morning (it's the first pic above), then insecurity came in and I got worried about the northern light that's just a week old.

To be fair logic is telling me the NL should be fine because the sunset sherbet is the tallest of them all and it's been fine since I cranked the light down (I have high hopes for this one, it's a lovely strain).

The babies being in larger pots are obviously closer to the light but I've got it max distance away and dimmed to the lowest so I was worried about them.
