Advanced Lighting Spectrums for T5 Floro and LED

[hyroot]

Not sure. Im guessing its the 420nm. Just from what I saw in my par t5 recently. when I first got cfl's for my mom plants. They took off like crazy using all blue bulbs. Those cfl's are around 470nm. Plus the apache led's only have 460 blue diodes. Nasa contributed to the building and design of those panels. So I think scientists at nasa have a better idea of this than I do. There are some studies in oxford journals about melatonin in plants. But you have to have a subscription to oxford experimental botany to read the whole thing. But you can still read the abstract for each study.

Now I expect a much better yield with out the coral waves now. I was all about those bulbs too. For the IR though.

Well, bad fuckin news guys. The leaves are curled due to another thrip infestation. I think I caught it early enough this time that I nice dose of Monterey should do the trick. I can't believe I even started over from cuttings and those fuckers still managed to find a way back in. I'm sure it's because it's summer, and stupid fucking bugs are finding a way in through the cracks of my house and bringing in the thrips with them. I keep finding beetles and different flying bugs from outside invading my grow space.

I HATE BUGS!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I sprayed all my plants, cuttings, and seedlings with a light dose of GoGnats cedar oil spray. The shit is pretty dangerous to plants and I have had some issues using it before, but I want to "hit" the thrips to at least keep them from multiplying until the Monterey Garden Spray gets here.

Sure has been a rough Summer, damn bugs need to GTFO!!!!!!!!!! Fuck you bugs!!!!!!!!

BUGS SUCK IT. I have a tri-level house. How hard shell worms get to the 3rd level is beyond me, but they do

I run an 8 lamp fixture over my seedlings and cuttings. The lamp is only 10" with all the lamps on and I've never had any problems. The more light the better. They will just stretch a lot less and get beefier stems if you have more light from the get go.

Yellowing on the edges does not mean they need food. Brown tips are a sign of over fertilization. What are they in right now? It could be a PH issue. It also could be that they are still clones and it's just stress.

Wait a sec, they are in 5 gallon pots already?!?!?! If they are just clones and they are already in 5 gallon pots, you may have a problem. I have NEVER had good luck putting tiny plants into large containers. The roots get "lost" in the pot and can't find the bottom. It's most likely the fact that with tiny little roots, they will not get enough oxygen and the roots will also just rot right off since the amount of water they will have to get through to grow.

It's really best to start out with a small container, then transplant up as you go. I would transplant to a 3" x 3" container depending on plant size. Could you post some photos please?

On the amount of light, I disagree. 108 watts is plenty, so why waste electricity? HOWEVER, Fonz is right about pot size. I use APs, but have a range of them. I start my cuttings in my DIY bubbler, then transfer to small ~ 1L size APs. The beauty of using APs, is you don't need to distrub the plant, just drop the whole thing into a larger AP.

Yellowing edges is a magnesium deficiency. If yellowing starts at tips and becomes blotchy yellowing, its nitrogen and / or phos defieciency.

There are many lamp manufacturer's that don't use anything other than 450-460nm blue in their grow lights. Lots of DIY'ers that do the same. I've never seen anyone complain about that spectrum thus far. It seems to be able to be used by the plant for all the necessary plant processes.

Makes me wonder though if it can still be used for the ripening stage last 2 weeks or so of budding to increase trichome.

 

[mrcourios]

Well they're looking much happier,growth from the last couple nodes looks much darker green and the yellow pin points are almost gone and much less noticeable with no brown tips. I gave them a very small weak feeding but not sure that was it.
Maybe stress from the change of lighting and or re-potting with a very rich soil. They were on the side of a room with a 1000 watt HPS. I'll just watch them for a couple days and see how they do.The 2 flora suns,1 coral wave and 1 aqua sun are about 8" away and they added 50% of their height in 4 days with the nodes 1/4" to 5/8" apart depending on the plant.(4 different strains) I got them laying down and will circle the pots with them.

 

[Fonzarelli]

I put my 1000w 3K Sunpulse MH back in the flower room along with the 4 Kessil h150 Reds. The 250w'ers just did not have enough evaporative power for my plants to keep them perky. I wish the Sunpulse had a better spectrum than your basic MH. The added Kessils help, but not by much because they are just not powerful enough compared to the 1000w. They match up better with a 250w. It's lame that they are so fucking expensive with what little power they give off.

 

[mipainpatient]

Sup all, nice to see ya still contributing to the "cause" (specifically poly, pet, fonz etc)
I'm going to keep to myself, getting too tired to pontificate for free but if someone wants to ask a specific question I will subject the terms to a search of my 2.4k pdf archive of relevant academic (peer-reviewed) studies and we'll just see if we can't answer the question by just pasting the relevant quotes. Keep up the good work guys. FYI some strains can handle 12 hrs UV supplementation, others only 6 seems ideal, this may apply to some of your really blue/violet-blue bulbs too....
Peace,
MPP

 

[mrcourios]

Well I'm running 4 flora suns,2 aqua suns and 2 coral waves now about 8" away. Gave them another lite feed and gave the soil a little molasses. They really seam to be very healthy and a lot of new growth from all the nodes including even the ones right at the soil line. The nodes are so close together that it's tricky to find places for LST and one is almost ready to start going around the pot. The only growth that looks ugly is the original leaves from when it was cut.

 

[Fonzarelli]

^^^^^^That's a lot of 400-420nm Violet light you got going on there. Could you post up some photos of your lights and plants please?

My flowering room is finally starting to get better now. Like I said in the other forum, the 3K Sunpulse 100w MH works "ok" but it takes a few days for the plants to stop stressing out from the light spectrum. They are getting greener finally AND the 2 seeds that I created "cross-breeding" some Cali-O and Sour-D are BOTH FEMALES! They are the first seeds of my own that I have flowered and they are 2 for 2 females which is super cool!

You don't get much for yield in the process of making seeds, but it sure is addicting! I created about 6 or 7 new strains.

They are as follows:

1. Cali-O/Sour D by Reserva Privada

2. Cali-O/Serious Bubblegum (The pure bubblegum strain is a pain in the ass. It wants to grow a bunch of leaves in a clump and doesn't branch out for shit. Now that I've crossed it with a Sativa based strain, it wants to branch out quite a bit more which is nice.)

3. Cali-O/Lavender (Soma)

4. NYCD/Sour D by Reserva Privada

5. NYCD/DJ Short Blueberry

6. NYCD/Lemon Skunk by DNA

It sure is fun to cross strains, but it's really easy to get carried away with the pollen. LOL The shit gets everywhere. I ended up with about 200 seeds of each strain. LOL

I guess I could become my own seed bank for a couple months if I wanted to. Not sure if that would be a good idea though. I'm also not sure about the business ethics of combining other breeder's strains. I can't wait to see the final results and how they compare to the original versions.

The seeds sure do vary from one seed to another. It's interesting to see how some seeds are more Indica influenced or Sativa. For instance, one of my Cali-O/Sour D plants combined the Indica parts of both strains instead of Sativa so it is very short, stocky, wide leaves and thick just like a pure Indica would be. Then, right next to it I have the same seed that got Sativa influenced and has very long, slender leaves like a Sativa. Well, you get the point. Fun stuff.

just breed them back with sister and every which way you can. but damn thats lucky ive actually had my troubles with pollen now that i got the hang of ot im sure i could produce mad seeds but im so carful about collection(as early aas possible i dont like the idea of free floating pollen) an how i pollinate.

hell i even sneezed on my pollen and i didnt get that many seeds. looks like i need to let my males go longer perhaps. shit from all my crosing i thing i got maybe 10 seeds a plant roughly and fewer than 5 on 2 plants. ive only breed successfully 2x(single pollen multiple plants/strains so succesful series i guess) and managed to cube one strain which i just flowered out casue it was crap and more of a practice. i have other seeds im working on now.... but once again im in a pickle still waiting on the funds to buy these tens half tempted to hock my ps3 i never play....

props fonz keep breeding thats all i can say!

I know it's quite blue heavy,the coral waves peak at 420,the aqua suns peak at 430 and the flora suns are 460 heavy. The only other lamps I have are 3 red suns which I got for bloom. Plants seem to be doing well and the nodes are definitely close together. I may swap in a red sun later but I'll wait a bit,they only started with this 8 lamp combo this morning.

some interesting stuff and mostly the basics on photosynthesis.

 

[mrcourios]

Well the leaf problem I have that I thought might be nute or stress related turns out to be thrips. I think I caught it early.

Yeah, LOL, the first male plant I got out of my seed order was a Cali-O. Aggressive growing as fuck. Put out mad male flowers. I waited till about 30 of the pollen sacs were totally open and dropping and got carried away, took the whole plant upside down and shook it over the top of the Sour-D that was half-way into flower. I knew I was going to regret it later.

LOL. Anyway, the whole room got pollenated. Lavender, bubblegum, regular Cali-O(which I now have pure). I got about 1000 pure Cali-O seeds. That strain was a pain in the ass. It's really a nute hog. I'm not used to feeding that heavy so she got really yellow and didn't finish well. I ended up harvesting her early. Definitely needed a larger pot and more nutes. Also a taller area. I'm sure One could get some huge buds of of the Orange, but I just was going after the seeds at that point anyway.

I don't know what to do with all the seeds now. There is no way I will be able to use them all in time. Is there a way to store seeds so that they last a super long time, like 20 years?

I know how that shit goes. I really hate them. Hit the leaves twice with monterey and flush the soil out with 1/2 a mosquito dunk mixed into 5 gallons of water. That will take care of the larvae in the soil so I've been told. Mine are on the way.

I spray all my shit down with GoGnats twice. The first time with a 1/8 tsp to 8 oz of H2O. Then the next day 1/4 tsp to 8 oz H2O. The plants HATE the cedar oil in the GoGnats. A lot of leaves will fall off later on because it fucks the plants up for a short time. That's why I bought the monterey stuff. Never used it yet. Anyone know about the mosquito dunks and if they work/harmful to the plants?

 

[Fonzarelli]

I just set up a new little room with a 250w 6.5K MH + 48w of RedSun. Check it out! So far I like the light spectrum, the MH lamp is a lot nicer than the Sunpulse shit.

you can give them to me.... but honestly stroring seed should not be a problem i doubt youll ba able to use them all like you said but you can dry them put them in a bag and toss them in the fridge this is supposed to extnd the life of seeds, but honestly i got seeds that are 5 years old from when i was buying bagweed when i was 18 and those seed still pop fine. and my seeds have never seen a fidge just a silicon pack inside a medicine bottle stuffed with a few baggies of labeled seeds. put in a cool shaded place.
