Spider Farmer Se3000 + Gelato

[Star Dog]

I've the opportunity to test out a Spider Farmer Se3000 bar style led.

Spider Farmer® SE3000 300W Full Spectrum LED Grow Light - Spider Farmer UK

spiderfarmer.co.uk

This is my 1st grow with a bar led so it'll be interesting to see how it goes.

I've got 2 gelato seedlings ready to be vegged and I've some clones from various strains also ready to be vegged

In the next few days i'm going to repot the the gelato and two clones into air pots then get the branches tied down.

Edit:
I just wanted to add it's..
Coco and Ionic 1 part nutrient.
Temps 20/25c Rh 60/70%

 

[Star Dog]

There's not much happening just now the plants have been under T5s so I need to introduce the light a bit at a time.


I topped 2 plants last week I need to get them re potted and tied down.

The two plants I topped I tried grafting said tops to a root ball I've just flowered, idk if it'll grow if does idk if the growth will be veg growth or re veg growth?

But we'll find out soon

Since switching on the led I've had to increase the ec to 1.2ec the run off is still 3-4 points short so I'm going to raise it again tomorrow.

I'm going to leave things as they are until I get things back on track I'm anticipating a week.

I tested the draw from the light and it's 300w +/- 1.5w

Temps 22/23c
Rh 60/70%
1 part ionic 1.2ec 6.0ph
Light 70% power @34" height I'll lower over the course of the week.

 

[Star Dog]

Today I raised the nutrient strength to 1.5ec (Ionic 1 part)
I know that sounds rich for young vegging plants but they don't look 100% and the run off is suggesting it needs raising, I'm not going to quote the run off figure from the 1st 1.5ec feed it's so far out I'm hoping I've made some error, I'll know in a couple of hours for sure.

I've pruned back the clones and bent down the braches on the two king gelato, it's already been topped at the 3rd node I might trim 2 off I'll see how it goes, ideally I'm hoping to flower 3 or 4 plants.

Temps 23/24c Humidity 60/65%
Ec 1.5 ph6.0
Medium coco.

@Star Dog
What are your temp swings? (High / Low)
What are your humidity swings (High / Low)
What nutes NPK?
What medium?

After raising the ec they're back on track, the transition from T5s to led makes my plants use a higher nutrient ec.
Yesterday the run off was catching up its 1.0/1.1ec from 1.5ec so I lowered it down to to 1.2ec.

(pic from before)

I'm planning to flower the two topped plants and 2 of the clones but space might not allow.

So i've got something to try in a bid to keep them more compact?
I'm thinking about keeping one plant in 1ltr pot until after the stretch phase then re potting it?

I know for sure roots are still growing at 10/11+ weeks so there's plenty of time for a decent sized root system to grow after wk3, nothing ventured nothing gained

Temps 23/24c 60/70% rh.

 

[Star Dog]

I re potted the 2 king gelato tonight (5ltr pots) I'll re pot the others tomorrow I didn't have time to finish them before the light went off.


I'll give them a couple of days before I tie them.

Nice grow matey here's a pic of my autos under the se3000 . These lights are great in a 4x4 tent.

 

[Star Dog]

I re potted the remaining glukie pie and icr clone yesterday.

And I flipped the timmer to 12-12 tonight.
25c/60% Ec1.2 ph6.0
10" 66% power.

 

[bobqp]

Nice and healthy

 

[Star Dog]

It's surprising how quickly they come on, 30/35,000 lux 66% I'll lower the light further tomorrow.

I want to see how the 1ltr pot affects stretch after flipping, if it's effective I can't see the problem with re potting afterwards and still getting a good root ball and some nice buds and keeping it compact?

That's only based on a few observations I've made it's not in any way scientific

Let's see what happens?

 

[Star Dog]

I put the pots into a 1x1mtr tray next I need to plumb in the pots for auto feeding.

I've Increased the ec to 1.5 and increased the light power to 100% 45/50,000 lux at 12/14"

 

[Star Dog]

That's just over a week now since flipping.
Yesterday I removed a bag of lower shoots and gave them a general tidying up.

I also plumbed in the auto feeder I'm starting with 3 feeds a day 1.5ec.

I've only to net it now which I'll get done through the week.

 

[bobqp]

Great job matey. These lights produce Rockhard buds. Your whole tent should be just a layer of fat hard buds at harvest.

 

[Star Dog]

A couple of pics from today there's not much to note just now.


One of the plants is using considerably less nutrient than the others.

My system is pretty flexible I can control each pot if/when required so I've put a tap on that pot to get the run off in the same ball park as the others.

 

[bobqp]

You Gunna remove any of the big fan leaves. These lights can produce hard buds all the way down to the pots

No I don't remove leafs except a select few but I do clear the bottom 1/3 of the plants.

 

[Star Dog]

I got finished early today so I've installed the screen with some support struts to keep tension in the net

It's 39"x39" I've a 2nd when the time comes I'll lower for support.

The net is only fixed at the back the front is hanging from yo yos so I've used a couple of ratchet hangers.


To stop the plants raising it up.

I'll start tucking tomorrow that'll be 2 weeks since flipping


Ec1.5 run off 0.9ec, ph 6.0 temp 24/25c 65/75%rh, lst 25/26c

 

[Star Dog]

17 days after flipping.
Tuesday raised the ec to 1.8

I've taken a few leafs from the front plant to try and encourage the lower shoots up to the light it's very compact compared to its sister, I've also noted its not quite as far on with pre flowers as the sister .

They're looking nice and healthy but I'm thinking maybe I was a bit quick with the net it's looking like I might need to get under the canopy to level it out.

But there's plenty of time just now and it might be ok?

I've now got my run off dialed in now to 15/17% 3x a day. 6.8ltr total to 5ltr pots

My run off catch tank aka a tub

 

[Star Dog]

There's not been much change to note, it looks like the stretch phase is getting near the end.

The canopy is 17-22" +10" of pot height I'll measure them again later in week.
