DWC - White Widow 2 x 2 300w LED

[BCbud316]

This will be grow #3 and I have to say I have a lot more respect for the experienced growers. So far I've made serious errors with poor soil choice, watering and harvesting early so this grow is kind of a new direction to try and correct these mistakes and up the yield.

Set up
300W LED from Vipar Spectra
2 x 2 x 4 grow tent
Seeds: White Widow Fast feminised from Seedsman
4” scrubber with 76cfm exhaust

DWC is initially a 1/2 gallon res with a 7.5w LED, will then move it to a 3 gallon tub I've made up once the roots get going. Seed is germinating in rockwool and hydroton mix in a 3" pot with a shitload of drainage.

Currently have the water PH'd to 6.2 with some seaweed extract to help kick off some root development.

Had some time so got the full bubbleponics set going.

Water PH'd down to 5.9 with some seaweed extract added.

We have lift off

Feedback always welcome

Day 3, seedling is nice and healthy so far. Set to 18-6 light cycle

Day 4

Doing a little bit of maintenance on the lines so had a quick look at the roots and all looks good so far.

 

[BCbud316]

All going well so far, still a lot to learn about nutrients so I’ll keep levels low for a while and try not to kill the plant.

Near the end of week 1

Watch your rez water temp too. You'll get slime and root rot if the water is too warm/hot. But lookn good so far.

 

[BCbud316]

Would it be worth getting another 300w viparspectra daisy chained in the 2x2 tent for a single plant?

bringing it up to a total of around 270w from the wall.

 

[BCbud316]

First res change

Dutch Master growth A+B and a little seasol for root development

PPM 420
PH 5.5-6 (using liquid test, digital one crapped itself)

good luck

I'm on the same single 300w vipar, I'm growing in organic soil though

 

[BCbud316]

My water temps were at 71/72c so I've moved my air pump outside of the tent, see if the lower room temps get slightly cooler air into the water.

Good growth over the last 36 hours, getting the next set of leaves coming through in the first week is good news.

Im running the same light, tent and seed with my grow. Only soil instead. Good luck bro I'll be checking back to compare.

Awesome, we should start a white widow 2018 sub-forum

This is 7 days progress to the minute, really happy with how things have gone after the amnesia auto disaster

Nice man, subbed. Ive got about twice the space with 2 of those vipar 300s in it. Cant wait to see what you do with it.

 

[BCbud316]

Decided to get a second 300w Vipar, 270w from the wall in a 2x2 for flower should be enough to get those yields up

Nice growth yesterday as well, the res change did a world of good

What 300w vipar is pulling 270w from the wall?

What 300w vipar is pulling 270w from the wall?

Each pulls around 135w, going to daisy chain them

 

[Buds.on.a.budget]

Ahh 270 over the two lights, I thought you were under the impression your 300w was pulling 270 on it's own lol
They should do just fine

Hopefully man. I’m planning on taking clones from this grow, moving to a bigger tent and increasing to up to 4 plants with the 2 lights.

Plan is to try and get up to .5g+/w with a combo of plant training and dwc but I don’t know how ambitious this is with such low end lights.

Nobody seems to have a good sample size on results given experienced growers usually invest in cob or hps setups
