Simple Water Only Grow

Cobs are good if you have the room. Bigger panels offer better distribution of light and the ability to get your light closer to the plants. Trying to get away from cob in my tent. It's not optimal.

Very interesting. I've always considered FFOF RTU. I mean it's not super soil hot but its fully amended.
Have you Ran the FFOF straight without all the adds.
When it comes to amendments blood meal can have your soil cooking if you know what I mean.
Looking forward to watching this unfold

Cheers

I wanted to try out COBs for a while but I too felt the boards offer better distribution and also wanted to get away from that hot spot HPS style of lighting. Good to have you around to talk about LED!

Yup I have ran FFOF straight out of the bag and it is pretty hot no doubt. Great stuff. This LC's #2 mix consists of 60% FFOF, 20% added perlite, and 20% added worm castings so about 40% of the initial amendments have been diluted. That's why I added back amendments but like you are thinking it is a strong mix and that's why when going this route it's important to start the seedlings/clones in the base mix listed at the start without amendments. The hot mix comes in later when transplanting. If i added all those amendments to 100% FFOF I would definitely be scared

Looking forward to it...

Time to stop in for another mid week update before I go and mix the amended soil again I have decided to upgrade my lighting situation to LED completely.

First off you already know about my 2x4 veg rack upgrade

• 4ft 4 lamp( two 3500K and two 6500K ) t5 HO fixture at 216w

To

• Kingbrite 288 (x2) Samsung LM301H 3500K fixture at 240w with dimmer(576 diodes)

What you don't know is the top Clone/Seedling section will be upgraded today!

• 4ft 2 lamp( 6500K ) t8 fixture at 64w

To

• 2ft Barrina Full Spectrum(assuming 4000K ) LED plug and play 8 pack at 80w(10w each)

I probably won't install all 8 of the bars. I'm thinking probably 4-6 but it is nice to have extras if needed. The Kelvin rating was not stated but I'm assuming full spectrum is 4000k and the spectral chart looks good. What I like about the plug and play lamps is they easily connect to each other and they each individually have on/off switches.

I'm really liking the idea of these upgrades so far. The bottom section will provide better veg results and I'll also be able to flower an auto or two under it when I feel like it. The top section will have more of an even coverage with the versatility of placing the 2ft LED strips. I'll more than likely get better seed/clone results and the increased spread in coverage will allow me to try out growing some microgreens.

I am also upgrading the lighting in my 4x4 Flower tent!

• 600w HPS

To

• (2) Kingbrite 288(x2) Samsung LM301H 3000K fixtures at 240w each(480w total) with dimmer(1,152 diodes)

It is going to be a lot of fun to see how everything goes with all this new stuff. At any rate the seedlings are doing well and will soon be moved into 1 gallon containers and then placed into the bottom section to enjoy some 3500K LED lighting. After they become established and go through a touch of training they will then be moved to the 4x4 tent under 3000K LED lighting.

I will be very interested in your finding after making the switch. You will definitely save a bit on power but looking forward to your comparison on buds. Are those kingbrites the respec? (including far red)

Yes I too am interested to see how the buds compare to past runs I have had with HPS(tried and true). After a lot of consideration I ended up not going with the far red diodes for a few reasons. Just Samsung diodes only.

Here is my reasoning:

• I want to see how Samsung diodes preform by themselves
• I didn't want to mix different diodes on the same board in case certain types fail before others
• The boards with Cree XP-E2 red diodes cost considerably more than the Samsung only boards and I am skeptical of Epistar
• For the price increase of the Cree XP-E2 I can always add stand alone red diode strips later on if I feel the need and not lose any money I wouldn't have already spent initially on a mixed board
• I went with 3000K because I seem to see a lot of people having success with that kelvin rating during flower and those that do use 3500K usually use it in conjunction with the far red diodes. What's nice is I already have that 3500K board in my veg section with only Samsung diodes so when I grow an auto or so under it I can determine how well it does as a stand alone without the far red addition.

yeah i use 3k start to finish. No issues with stretching

Thank you!

That's good to hear! After searching around I've definitely seen a few grows that do very well under just 3000K with no abnormal stretching. Also when I compared spectral charts of HPS vs 3000K Samsungs the LEDs have more added blue anyway so I figured 3000K would be just fine since I've vegged plants under HPS with no issue.

Can always use day/night diff to squat em if ya need

Are you talking about day/night temperature differences, or light hour adjustments out of the norm? This sounds interesting.

 

[Aqua Man]

Day/Night temps differences. They affect internode length. if you go cooler day and warmer night. if equal the effect is not much but once you go a few cooler during the day compared to night its noticable

I'm starting to read up on DIF now. I knew that temperatures had a role in growth rates, but I never new that a cooler day/warmer night was a technique used in greenhouse growing to manipulate internode length. Very cool!

Alright! Things are about the start going a bit faster now I just transplanted the seedlings yesterday into 1gal containers with the amended soil mix and moved them to the bottom of the veg section under the Kingbrite 240w LED fixture( two 288 Samsung LM301H boards 3500K ) at about 24" from the tops. The light is dimmed to about 60-70% right now. After they start taking off I will finally begin mainlining. I'm eager to try out this training technique alongside these new LED lights. So far things are looking good.

Thanks! It's good to have you here along for the ride.

I noticed the pictures are coming out a bit yellow so I'm going to try some adjusted shots. I have two cool white settings and I will post both of them below. Let me know which of them you would prefer or if I should just keep going with the normal settings posted just above.
