Rhetorrikz - LED Grow - Coco

[rhetorrikz]

Thanks man i tried another photo today with the led off... see if this is better?

This is a suprise i got some second hand cpu coolers for $5 ea.and after a few hours they turned into this

It draws roughly 150-170w the chips are 2 3000k and the center 6500k running @ 1500ma .

Ok big change clones from the cab up potted and moved to flower 4 days and pistals everywhere evenly through out .. good signs!
So the slow as center plants .. best one was on the right under led cob kept and put outside to finish flower 2 others compost just dissapointing. Also there were no noticeable differances with the one under the hps so wasted time with that idea. lesson learned if things aren't progressing well in transition to flower turf em ..
Been flushing for a few days now ph 6 tap water cloudy trics waiting for some amber .. havent checked ppm of runoff yet?

You can't find out if you don't try, you're doing is all a favour by doing this grow. Then buds look very frosty, thick too... Keep up the fine work rhetorrikz, thank you.

KiG cheers

cool made DIY light

great garden,nice buds and lots of space.

keep up the good work

Thanks guys!
Been busy here, made a small diy carbon scrubber and a drying box harvest and trimed im guessing some 250g
This round of clones is looking better much more uniform, all started flowering well under the leds . Temps have been better ranging between 70-90f.. high temp during lights out
Yesterday spread out and tidy up trim lower growth, took some clones, got the veg cab running . Last watering was 2 days ago that was 5ml calmax, 1tbls epsom salt mixed in 10 liters.. so
Today they got a sprinkle of great white microb powder and a feed of 15ml ml a ,15ml b , 5ml nirvana - 10L 600ppm ph5.9 and ive been using a phosphoric acid ph down

 

[ganjazz]

How many watts total you have now?

And how mush where the costs for DIY light?

 

[rhetorrikz]

Ok these are estimates, the LEDs both draw around 170w , the cree 4 cob light about 200w - 220w with pc fans and the cheap no name 3 cob light about 150w - 170w with pc fans
So all up about ~700w actual

Cree cob costs : cxb3070ad 3000k x 4 ~ $150, meanwell hlg 185 hc 1400 ma driver $100 , heatsinks $50 , fans $40 so all up ~ $350

No name cob costs : 2 3000k warm white and 1 6500k cool white ~ $20 , drivers 3 50w 1500ma $45 , cpu coolers $15 all up $80

Will the cheap cob setup last? What will fail? With my phone app lux meter im getting similar readings between them and i find not using reflectors or lenses with the cobs they're staying cool and have good coverage ..

 

[ganjazz]

thanks for explain,

430 dollars for 700w draw, thats a good price for make it yourself.

 

[rhetorrikz]

No worries ganjazz, i think the $ per w on the cheap led cob is great value about .50c per w... my exchange rate was terrible and postage threw the price up.. but they have been great lights

Pc fan mounted to a stainless steel mesh pen holder wraped with a stocking. mounted inside the base of a coffee container filled with activated carbon. drilled about 400 holes ..

Slow draw through zero smell,, alot better than i thaught actually.. there are 4 racks, wireless humidity sensor and intake vents with filter mesh. A small window in the bottom with a desiccant moisture absorber. humidty is about 65%

 

[rhetorrikz]

Here is the clones in the veg cab , tead you'll like these lazy mini hempy dome cloners there is a layer of perlite in the base and toped up with coco watered once and misted with ph'd 6 tap water
Set and forget hopfully. In the past ive just used a single 23w 6500k cfl for this stage untill roots form.. this time im trying the twilight blue and white dimmable led with the dials turned right down on minimum

 

[Luluthia]

Way interested in the diy. Im working on an arduino grow controller specifically designed for tent grows. Love the ingenuity.

 

[Stinky Snid]

Nice rack! very good design with the venting out. I'm going to improve mine now that I've seen this one... Thanks rhetorrikz

KiG cheers

Very inspiring rhetorrikz!

You're damn right I like 'em!
In my hot and humid world, I put a 1/2in (ish) hole in the top. This also allows me to spritz them easily... tops just stay in place and I spray thru the hole.

 

[rhetorrikz]

Ive done domes with holes for the same reasons ease of misting but last time this worked well.. lazy cloning.. their first misting today 9 days without touching them
This time the cuttings were taken a bit later than i like .. the plants had visibility started to flower so i guess were trying monster croping for the first time. iv heard it takes a bit longer to root..

Took some nugs from the top dry rack and sealed in a jar were @ 72% getting close...
Ive been waiting to get some harvest numbers , i racked the 1 plant under the es100x3 and 1 plant from under the p100x3 seperate.. maybe tonight..

 

[rhetorrikz]

Ok curiosity got to me
100x3 - 114g
300 - 102g + single cola plant 55g
So 271g dry is about ~ .8gpw with the 100x3w leds
Which is great! but i think could be improved upon because there were a few issues with salt build up and n toxicity then flushing led to magnesium deficiency i think the 300 plant had it worse and shows in harvest numbers
All in all happy harvest

 

[ConstantGreen]

oooo hell yea, here come the monsters! I have some clones that look just like yours now and are showing some signs of flowering. I cut them like 5 weeks ago so I think the looong time I've been rooting them in low light causes them to start flowering.

My sexbud flowering now were clearly monster cropped and the outcome looks really cool. Super dense nodes and tons of branches.

 

[rhetorrikz]

Just a quick update under the diy leds

 

[rhetorrikz]

Bit of yellowing showing through out the girls . Might ned to up the feed a lil now ..previous feeds have been canna coco 10ml a + 10ml b + 5ml calmax to 10L tap water ph'd to 5.9 with phosphoric acic 480ish ppm.. noticed some slight tip droop / clawing ..why ? temps 65-88f rh 65%
