Irish the plants look really nice. I love all the perlite, I bet your going to be real pleased with the results. The growth is looking real nice. Good work Irish!!

That HS will be fine, hell you already know that though. A little pH problem is healthy every once in a while- LOL.

ya i could tell they had a PH problem once i got them. it locked out a few things, but i am going to add some cal/mag plus to help them out. the LSTing is going real nice. nice even tops on each plant so far. good thing i caught the PH problem from the get go. all new growth looks good though. i at least i wasn't in flower when i had that little problem.
 
re: GLH 600W LED Grow

looking very promising ,I hope they get fat, juicy buds for me to smoke LOL

Also just finished smoking a quarter of irishboys hindu skunk ,,, and i was very happy with the results...

and i hold extremely high quality standards !!! proof is here LED's can produce awesome results, but can they produce enough buds in the end to be a reasonable light choice...

so how many licks does it take to get to the center of a Loli Pop?
 
re: GLH 600W LED Grow

It's good to know you add a lot of perlite - I just got back into dirt farming when my buddy gave me his 'ghani mother, and I repotted in 50% perlite, 25% worm castings, and 25% peat. I screwed up big time with the PH... added some down WAY too strong... but like you said, it flushes faster so I was able to save the plant.

Nice start to the LST... I love how it's like a bonsai of cannabis. +8
 
re: GLH 600W LED Grow

hey irish
looking good man I still need to read from the start but just wanted to let you know im lookin in
im very interested in what 600 watts of led light can do. i wanna make a diy light of my own someday

Beside the PH problem are you happy with your mix? Was it a indoor grow?

I'm looking for a mix for outdoor grow soon.
 
re: GLH 600W LED Grow

Hey Irish,

How are things bro? The ladies doing ok? Nothing crazy or anything going on?

Hope all is well bro!

-Go

the one good thing about these 3w leds is the heat is their, so now i dont have to run my heat like i had to do on my last grow. it coasted me allot of extra cash to run the heat the whole grow, where it would have been cheaper to run my 1000w hps. so the heat on mikes leds is a good thing for me in the winter time, but i am curies to see how it dose in the summer time? i know i would need to run a vent fan but it also gets around 100-115F* in the summer where i am at. so either way i am screwed.

Irish,
I would think you'd want to exchange the air in your area at least once or twice per minute, no matter what the temp is. And when you consider the price of a z of good smoke, then the tiny amount of electric used for exhaust fan, is like minicule. And no, if the price was $1200, i still would'nt buy it. These lights will eventually be close to price of a good 600hid, if they want to sell them, and then i'll think about it !! I mean in the beginning of led, all the sellers we're compareing a 100 watt led to a 400 watt hid, and now they are compareing them watt for watt. Ha !! I really think some people would be happy with leds even if it takes 1000 watts of led to equal a 600 watt hid. But not me !! I was excited when I 1st. heard all the original lies, but after all the failed grows, and now somehow they want watt for watt. Don't kid yourself, you'll still need an exhaust fan, if you want your girls to breath fresh air, and 600 watts of electric is same no matter what, so tell me where is the advantages ?? I am in no way a led basher, And Mike, I hope you prove us all wrong on this grow. You seem very confident, but then so did Cammie !! You could'nt have picked a better man to conduct it !! Go Irish !!:yummy::nicethread:
 
re: GLH 600W LED Grow

I don't think this is appropriate in the grow journal here. If your point was to remind Irish he needs to exchange his air, that's a good call, and it could have been left at that. We all know people hate and like led's. I thought we were over that at this point.

We just have to kick back and see what's going to happen...that's all we can do. Either that or buy a panel of your own, and see what it can do with your own eyes. Like me.

Until then, let's just leave it at that. The end results will tell us what Irish did here.

Peace and Respect.

-Go Green-

i know you still need an exhaust fan. or at least a door open. but my setup is fine the way it is. i have fresh air coming in and i have old air going out. my point is u dont need to run a big CFM fan to deal with the heat with leds.
 
re: GLH 600W LED Grow

hey, I'd believe it. 600w is 600w of consumption but a high pressure sodium tube operates at much higher peak temp than an LED diode so therefore you're whole "still need a fan thing" is debatable on the points of filtration and temperature.

what temp is the unit running at? if you touch it with a piece of plastic will the plastic melt? thats what 1kw HPS does, the ballast generates loads of heat too. haven't run the experiment on the 600w though haha.
 
re: GLH 600W LED Grow

I have to agree with Slowpuffer that air exchange is essential to healthy plants, and I don't think keeping a door open is enough to accomplish it.

Exchanging air once or twice per minute is optimal, but even once every three minutes seems to work.

Without CO2, it's important to have an exhaust fan and good flow-through ventilation, regardless of the temps.

Bring the air in through the bottom, swirl it gently around with a circulation fan, fix the ladies a Mai Tai, and look out.
 
re: GLH 600W LED Grow

Good luck Irish. I'm excited to see how your grow goes. I'm planning on upgrading soon, so this will help my decision whether or not to stick with LED's.

My UFO did great durring veg, but I knew even with my noob mistakes I could of yielded a lot more with more wattage durring flowering.

Good Luck!

Well that isn't debatable but you don't need an inline fan for air exchange.

Ok, I tried to to think up other ways to exchange the air at least 3 times per minute without an inline fan, and most of them involve keeping the door open all the time, which generally isn't an option due to light schedule issues.

I might be missing something though.

That air exchange needs to be 24/24 in order for plants to really thrive.
 
re: GLH 600W LED Grow

My Friend hook up his exhaust fan to a swamp cooler thermostat, it cycles off and on to the heat, and save a little bit of $$ on his power bill.
The ideal of venting into different grow rooms seem good, but in the desert all the light cycles are at the cool of night time.

SS I gotta question for ya [or anybody else for that matter.] Assuming one has a Vegetorium:rollit: AND a separate Floratorium, have you ever set up a grow schedule so that the air from the flower room during dark hours is vented into the veg room while it is illuminated, and air from the illuminated veg room is vented into the darkened flower room? Since the plants are doing oxidative respiration in the dark and burning carbs with O2, releasing CO2 as waste, and just the opposite in the light, the CO2 evolved can supplement the air in the veg room while the O2 evolved as waste from photosynthesis can help in the dark flower room. Minor problems with this: not perfect over lap in dark/light cycles, humdity might be an issue, but these can be dealt with. "Is there anybody out there?" that is doing this?:yummy:

I don't know if anybody is doing it, but I LOVE the efficiency of your idea.

The problem with that is thinking that an exhaust fan's main function is handling heat.

An exhaust fan's main function is to provide proper ventilation for the grow space, and heat management is a byproduct of that.

If you can't control heat issues when you're exchanging the air once or twice per minute, you probably need a bigger space, less light or a different light technology, or both.

I wouldn't cycle my ventilation on and off because that's like choking your plants intermittently.

At least, that's how I look at it.
 
re: GLH 600W LED Grow

it is funny how allot of people dont understand how much a good vent system setup in needed. just cause you run leds dosent mean you dont need a vent system brining in fresh air. dont get me wrong you dont need the big big vent system you would need with a 1000w hps. but you still need to vent the room for optimum growth. i always have fresh filtered air coming in, and have fans blowing the air out the door when i am vegging. then one i am in flower the vent fans come on and the filter is hooked up. but fresh air is a must. that is the #1 thing a grower should have before growing anything.
if anyone worried about vent fan noise, their are quite vent fans out their. Get a S&P vent fan, i love mine it is so quite and uses next to no power compared to my old vent fan. bad ass fans.
