They like the soil.

 

[TheRoach]

Big Bud growing strong. They needed a bigger pot.

This is how I transplant:

Thick stems

And thick branches.

This is how they look in day 19 flowering.

 

[TheRoach]

Today I will remove most of the fan leaves, add some fertilizer and raise the lights a few centimeters.

Have to say, that looks mighty purdy!

Thanks mate!

 

[TheRoach]

I defoliated all the plants

 

[TheRoach]

The clones are looking fine

 

[TheRoach]

More clones. I applied bat guano, terra grow, terra bloom and green sensation to the plants in flowering.

 

[TheRoach]

3 weeks fkowering.

Awesome set up, I'm in for the rest of the ride. I like how the cob setups give off a nice amount of light, I haven't tried them myself. Did you build them ones yourself? And how are you going about watering in there? Starting to get pretty crowded lol, love it!

Thank you, they do give a lot of light (65% efficiency I think)
I did build them using a tutorial from the internet, took me about a day or two to get them up and running. The lower part of the plants isn't as crowded so I can get my hand in and water them!
The COBs were a huge improvement over the 600w HPS I used before.

 

[dick23rk]

That's great, I like the diy side of things, was just never sure about the cobs. Then again I wasn't sure about LED in general til I bought a decent one. Good to hear it's an improvement. Prices have come down on a lot of LEDs so it helps there as well.

Im averaging 400-500 grams per 400w lamp. I love these COBs.

 

[dick23rk]

That's pretty impressive when you consider the energy and bulb cost savings as well!

 

[TheRoach]

25 days of flowering.
Colas forming!

 

[ScrogNub]

I'm in! I see that for the clones your using a mist system, is that what they call aeroponics? Also when the roots start growing then what you just pack em into a soil pot? The roots don't get all gimped out?

 

[dick23rk]

Beauties, very healthy looking as well. Do you plan to do a 3rd week defoliation at all?

Thank you for tagging along Scrognub!
It is an ultrasonic nebulizer, like the ones used in fog fountains, so I think it is fogponics? Haha.
I put them on soil as soon as they have a root system and they seem to like it, because they start growing almost rigt away! That being said, Im also careful with the roots when transplanting
