Lighting DIY 8x cobs and 4 DP Brooklyn Sunrise

[Jimmyclone]

Just ordered up 4x vero 29 2700k 90cri to swap out the two center cobs on each panel.
So we'll have 6x 3500k 80cri vero 29's and 2x 2700k 90cri per panel. After seeing some cri comparisons on riu, im gonna blend the two and add a little more red to the party...
Now. What to do with the 4 remaining 3500k chips... Decisions, decisions..
Cheers

3 week update
Topped all 4 girls 3 days ago. Slowed growth for about 2 days, but i love the structure that topping and training does to autos.. Couldn't help myself.. Will start some training here soon.. Tried going up to 300w for a day.. Too much, back down to 250w seems to be good again. A little over watering happened, as i usually use fabric pots, promix and hps and that combo dries your medium very fast.. With cobs, plastic pots, and a little dirt mixed in the promix it seems to stay wet for along time.. As i said a little learning curve here.. New chips are in the mail and ive been getting the second panel finished up and ready for the new chips. When its complete i will. Swap out the panel in the tent with the new and improved panel(90cri)

and begin the switch on the original panel..

Week 4
Growth has finally started to pick up a bit. I think the temps have been playing a big part here.. I bumped up the heater in the tent to a constant 25c about 3 days ago and have noticed quite a difference. Crazy what 3 degrees can do.. Very short for there age.. I got my new chips in, just waiting for some time to finish it up.. Small signs of cal/mag deficiency, i will give them a heavy dose next water..

Still some over watering issues.. These pots just dont dry out.. I dont like the same old nute water sitting it there for 2 long.. Ive been watering every 5 days or so just to change out the old. Definite learning curve.. Im really hoping they will take off now.. Not super impressed with therr growth..

You sure its CalMg?
I had a similar issue not too long ago and all it was, was me under feeding of nutes, they looked pale...

But you were commenting on it too, so I'm sure you have it under control.

The Fabric pot (smart pot) is so much better than those plastic pots (and a whole lot cheaper than the airpots)

Ya im starting to get some small rust spots on the lower leaves.. I have tons. Of fabric pots and have used them every run.. Just thought i would give the plastic a try... This will be the last time i think.. I like the plastic pots for training purposes though much easier and stronger to tie too..

I think temps have been the issue here.. Im used to trying to get rid of the heat.. Now i need it.. Im sure once both panels are running i wont need a heater at all.. Seems like they like the 25c under the leds.. I alway ran 22-23c under hps..

 

[Jimmyclone]

Upping the temps seems to have helped alot.. Pots were much lighter this. Morning and growth has picked up.. I said it would be a learning curve.. Hahaha.. Big calmag feed next..
Cheers

Plants are doing much better. Raised temps and lights.. Lights were much to low.. Im at about 350w and almost 3ft above the plants and they are finally starting to pray.. Gave a full dose feed with humic acid and calmag..

and the farthest along..

I think the light was way too intense for them, no stretch at all... These are the smallest plants at this stage, ive grown... Mabe the 2700k 90cri's will help.. If i ever get around to finishing the other panel.. Soon..
Cheers

Week 5
Girls are starting to take off now.. The 3 veggers are still growing and gaining some height.. [HASHTAG]#4[/HASHTAG] just wants to flower, so let it be.. She got her first dose of bloom nutes yesterday.. The rest got a heavy veg feed.. I should have some time at the end of the week to finish up the second panel and get her going..

And the flowergirl....

Cheers
