LM561C strip grow (660w). 1.5mx1.5m. Bubba Kush 2.0. 1st Timer

[superspudz420]

This is my first attempt at cultivation. Fantastic. I have a 1.5mx1.5m space in which I plan on growing 5 bubba kush 2.0 clones. I am growing in soil, all the way up to 39 litre fabric pots. They've already been on the go for 11 day's now under 1 light. Got the fixture drawing 300 watts, the plants are already growing quickly so I will soon put them under both fixtures. Been attempting to LST them, and they have responded well - just need to figure out what colas I should allow to develop and what ones I should cull. So far have been bending the plants in such a way that I don't have to cull of most of the natural development, however some colas are growing real close so I may have to get rid off them. So far so good however.

They've been getting ph'd water, nothing special. I hope that I can eventually get these growing on a trelis net and attempt to scrog them. Just trying my best to achieve an even canopy. Few plants are currently bushing out, will trim them to ensure only the colas I want to develop recieve full light. I may try to train the plant to grow around the pot's eventually installing a tomato ring for a bit of structural support, but I am unsure as of yet

hi spud,
did u build the light?

 

[blowincherrypie]

looks like u have the right idea.. good luck!

hi spud,

https://www.rollitup.org/members/diyled.986882/ built it for me , 5x double row samsung lm561c's mounted to ally powered by a 320W driver. I have two of them. Would highly recommend the guy. You could build the light If you wanted, could give you a partial parts list if you like. I'll upload a few more photos of the fixture after if you would like? helllllaa bright.

looks like u have the right idea.. good luck!

Cheers man, stick around I'll be updating as I go.

Good luck with grow. I'll follow along.

DIYLed's lights are gorgeous on his web site. Very nice like a McLaren road car.

It's been a while.
The ladies have been in their new pots for a little while now and they are loving it. 39 Litre fabric pots. Lights running at full capacity. In two days it will have been 5 weeks since the clones were put under the LED's.... I reckon I am going to put them into flowering very soon.

I must say LST'ing the plants gave me fantastic results . I do however have a poor scrog screen which fails to pin the buds down... I am also not sure if it's a true scrog, as I have nodes coming off the plant at varying heights.

LED's are giving really good light penetration and very good coverage, no complaints with the fixtures I must say. I read today in a grow magazine that UVB lights can help a plant to produce more resin, sort of like it's own natural sunscreen. It stated that supplementing your grow space with a UVB fixture that draws 10% power equivalent of your main light i.e use a 60w UV light if you have a 600w main light. I am going to read more into this - has anyone tried this?
edit - been reading through this post -
https://www.rollitup.org/t/help-regarding-choosing-solution-for-adding-uva-uvb-leds-to-a-diy-cob-led-grow-light.971826/page-4
Looks like UV is a bit overkill for a beginner. Interesting still however, if anyone has any ideas as to what I would need to install to supplement this area then please go ahead...I may look into it in the future (the same goes fro the deep red's you can apply just after lights out) I am aware of the risks of UV, I have purchased wifi enabled sockets, I could install the UV light to the wifi socket, and turn it off before entering. The sockets also allow you to create time programs - quite handy !

I am also noticing tiny burnt tips on new sprouts on one plant .. any ideas? No nutes have been fed so far. going to keep an eye on this...
edit - diyled said probably light burn. Just made sure lights are high enough. Should be cool now

More pictures to follow

I have been pruning as I go along to maintain good airflow and light throughout the plant. Once I take some clones, I'll flip to flowering and then strip them lollipop style.

Looking good. No it is not a scrog but lots of people think it is. But will be handy for the colas either way.

Yeh, I picked up online that a true scrog has it's plants branches at even heights with the nodes growing from almost the same height all round.
It is easier said then done, clones grow however they feel, with nodes growing asymmetrically. I LST'd the plants and that helped to get them growing horiziontally, I struggled to get the plants to grow exactly how I wanted - but they are spread enough so I am happy... especially seeing as this is my first time.

Try raise the lights a bit if there burn just on the top. 18"+ is a good veg height.

Look very good.

Thank's, I did actually do that after taking those photographs. Should work out well ... Very pleased with the lights, thanks. flower time soon.

- Need to get my head round what nutes and a nute schedule .... Looking online, it appears that the brand of nutrients does not really matter, my plants just need some as the nutrients in the soil start to become depleted... So many brands all with different claims. Advanced nutrients keep popping up but they look expensive for what they are, and a friend has recommended dutch pro. Would be good if anyone could suggest me some.

Thats gonna be a great harvest with 5x10 gallons pots!

Btw, did you top at all or just go straight to LST?

Thanks for jumping in ! I really hope so. 5 weeks veg also helps....
Nope I havent topped the plants once. I have only pinned down branches through LST, and cut off smaller ones.
I got good results through LST, I think next time I may top the main LSTd branches. But so far just LST has done wonders.

One week after switching to 12/12 flowering stage.

Put some sticky traps down, had a few little flies, they caught em nicely...
Gave them a feed of dutch pro a and b aswell.
Will defoliate as I go, and I plan to strip the majority of fan leaves at week 3. Looking healthy so far, some leaves looking a bit pale / lighter green - so I hope the nutes will kick in and maybe boost the darker green colours.

Currently watering the plants about 20 litres each, once a week... then removing run off... hope this is correct

Lights could potentially come up a little, but no burning really. Oscillating fan in the corner helps blow through the under sides ... excellent penetration from the LED's still.

Future grows, I will mount the pots on some kind of grid I think... run off is aggravation.

Sticking to a simple nute regime I may purchase the dutch pro 'explode' ... 3 bottles of nutes is simple I think, I am not going to get sucked into advanced nutrients etc. I just want to grow good consistent plants and not pay an excessive fortune.

Nice thread buddy.the girls are looking great.gives me an idea of how my first grow will look.
Well i hope so anyway..have same size room different lights and i will b using soiless.

I will b lst'ing very similar as that what ive been doing outdoors for last 18 years or so
I tip at the third set of true leaves so you have 6 laterals to train .i use to use fence wire to peg laterals down and the many branches that grow off them.i cant put scrog net in as i have laminated chipboard room so i cant reach to scrog.i think i buggered up there. lol.so im going to use 2 gardland trays which are 100cm long 40 cm wide and have a slight slope so runoff can b takin out from one end.im actually putting a mesh screen on top of the tray so i can tie down the branches to it as they grow
+ having the smartpot out of the tray sitting on the mesh helps the bottom of the pot dry out and a better flow through effect when watering...

A true scrog is where your nodes are coming off at the same consistent height - it's harder then makes out. The net is not great but I have been using it to pull over taller colas to give the littler ones more of a chance. Run off is a pain, in a perfect world the smart pots would sit on a grid with the run off dripping down. I've thought about it, and I could maybe use plastic trays with hatched bottoms, only problem would be my fifth pot in the centre - it would be sitting where the four trays corners touch - I could leave this plant in its saucer, and attach a pipe/hose to the bottom of the saucer to drain below.

Trimmed lots of fan leaves blocking light to bud sites etc, think I will do this again next week and then major def. on week 3.

There are some small colas branches that are spindly underneath the canopy that have formed with bud sites - any advice ? Cull them as they will be poor buds ? Keep them to improve yields ? Or will culling them improve yields by fattening the better buds?

High of 22.9 degrees
Low of 16.1 degrees
Sitting at about 60% hum. Temps could come up a little but looks ok.
Lights now raised about 16inches from the tallest branches.

Id cut those small branches off.,you could even clone them if you wish.

I was gong to use rhizo stands but they are 12cm tall .ill most likey get them when i know
i can control the heght okay..they are made so your runoff can go to a catchment outside of tent..you'd have to have the rhizos try up abit i gather so water can run into the catchment..the small suits 16ltr 28cm dia rhizo pots and large 38ltr 52cm dia.not sure exactly on measurements but im close..with the back 2 you use elbow fittings and the front 2 have T fittings then run to catchment .your middle can have T fitting also..prices are about $30-$50ea.a little pricey but i think they are worth it.personally id get them on some mesh above tray so the bottom roots arnt sitting in stagnant water ,and would help with more oxygen getting to roots.and when your feeding salts can easily flow out instead of building up on bottom of the pot..just my 5c..

Cheers max

Looking realy healthy. My current grows don't look like that never mind my 1st.

Good job so far. Anything weak chop out. If you cant bend other things out the way.
