LED grow NO.2, testing the Pro-Grow 260 and Rhino Seeds.

You have some great logs there yourself LetsSee !

Interesting re-veg stuff. Never tried that... i would think I would get more bud from a fresh grow. but interesting nonetheless !

Take care

So I have decided to up my game a little in the tent.

I will be keeping the Pro-Grow 260 of course but instead of the 80w of 2700k CFL I will be using 65w x 4 :) So that will be 190w of LED and 260w of CFL.

I will be keeping the 4 x 20w CFL until the plants become large enough to warrant the 4 x 65w. To increase the intensity of the CFL I bought 4 x stainless steel mixing bowl. (21cm D x 10cm H)

I'll drill 20mm holes in the bottoms of the bowls so I can attach them to the light battons.

I will hang the 4 x 65w out of the top of the tent directly over each of my 4 plants. This will focus more light on each plant and keep the nodes good and short.

I'm hoping this addition will create a much higher yield in the end. I think I will have a great grow tent when they are installed with plenty of light.

Has anyone here mixed LED and CFL in such wattages ? Would love to hear about it. I think 190w LED and 260w CFL are plenty for a 3 x 3 tent.

Re: LED Grow Log under the Pro-Grow 260, 2xBlueCheese, 1xBigBang,1xChronic! Yummy !

Hey All !

So it's time for another update on my LED + CFL grow ! And things are looking fine fine fine !!!
Things are getting rather exciting now at the 67 days old marker and 24 days of official bloom. I could see some tiny hairs 33 days ago but it took the ladies a week or so to really kick off into bloom. I wait until I can clearly see the pistils in a few areas on the plants as their hormones are changing slowly, so when the blooming hormones are in full effect I call it bloom time.

My 4 x 65w, 2700k CFLs arrived today and the tent is so much brighter. The lamps themselves are surprisingly very large as you can see by the pictures. They are about 25cm long and 13cm wide. When I unzip my tent it's like opening up a pirates treasure chest now :) A golden glow shines out through the zips ! I installed them today and they will be running for another 6 - 8 weeks. I'm not sure if I want them running for too many weeks as 450w might be expensive over time. I don't want to raise any eye brows if you know what I mean. Luckily they are only on 12 hours per day. I think they are going to make a massive difference to the yield in the end. The tent is illuminated from top to bottom so the plants will be soaking it all up. I have increased the speed of my extractor fan as I think there will be a lot more heat in the tent now. It will be important to find the correct extractor speed to keep the temperature at a comfortable constant.

I hope you like the pictures. I think the bud growth will be much stronger with the new CFLs. Those CFLs and my Pro-Grow 260 will blow these plants away ! I can't wait to see the yield off these plants. I wonder would the light I am producing from 450w give better results than 450w of HPS ? Any idea on this guys and gals ? Would love to hear your opinions...

Take Care

looking good lad. they are the same type cfl's as i've been using. questions for you, what size fan/carbon filter are you using. i'm starting to have a problem with odour's.

I use the Can9000 carbon filter.

There are a few places to buy them in Ireland. I went to a regular horticultural online shop for mine.
Shop around and see what sort of a price you can get. I prefer to do my best to order within Ireland so customs don't have a chance to check it.
I think I paid about â?¬70 - 80 for the filter. Money well spent ! I tried those odorsock types too but they didn't work too well for me. Not for long anyway.
Get an extractor fan speed controller on eBay too so you can adjust the speed of the air being sucked through your filter. Carbon filters like air that is drawn slowly through it.
Be sure you invest in a good filter... Stealth growing depends on it... The scent of weed can be detected by the most noobish of noses... Be careful !

If you go through my first grow you will see a whole section on carbon filters. I think I even gave a link to it.
If you have any more questions let me know.

Hey guy and gals.

We are at day 31 of bloom, my last grow under my LED took 13 - 14 weeks of bloom to finish so there is still 2.5 monthts to go !

2.5 months of bloom, bloom and more bloom !

They are horny as hell and producing lots and lots of beautiful lady bits hoping that their 'very fertile' prince would come into the tent and service them all heh heh !! :)

I don't have it in me to tell them that there won't be any males of their species around just in case they hermie on me ! I did wipe a little pollen on some areas of the lower buds.

I'm very surprised with the buds right now, they are filling out very, very quickly. There is a marked difference in the size since the previous week.

In comparison to the same time in my last grow the buds are much bigger and they are also denser. I think the 260w of CFL have made a difference.

I have decided to feed the plants a little less than the last grow. I think I had a magnesium deficiency due to over fertilization. I use the seaweed and tomato fert and bat guano.

The last feed 3 days ago was 4 heaped tea spoons of bat guano in 10 litres of water. I will be keeping a close eye on the plants so to figure out the best feeding cycles and amounts.

I harvested a very large amount of weed last grow and I think I will be harvesting twice that this time round ! Bring on the 1GPW baby !!! Whoop Whoop :) (hopefully) !

Hey SL just wanted to say that they are looking beautifully I had a quick question are you using any co2 for your grow or no and also people tell me that led is not good for flower reproduction obviously you are proving that to be false. I grow cfl all the way but am considering to get an led setup where did u buy yours

Hey Kali

I only started using CO2 yesterday, I was waiting for the parts to arrive. You can see my DIY CO2 and DIY reflectors for CFL in the DIY section.
The only other part I will need is a bubbler for the CO2. A bubbler creates an air lock so oxygen can't mix with the atmosphere in the Milk carton.
I'm using Turbo Yeast which is said to produce more CO2 than regular yeast at room temperature.
Even when I close the valve and shake the milk carton I can see the milk carton fill with CO2, I have to open the valve in seconds or the carton will explode.

On the subject of LED lighting, I use the Pro-Grow 260. It's a great light and you can check it out on hydroponics Hut dot com. It's really a great work horse.
It draws about 190w, even though it has the '260' in its name. I used this LED primarily in my first grow log (in my signature) with just 80w of CFL for heat purposes.
This grow I added 260w of 2700k CFL (4x65w) but only during bloom to give the plants that extra kick. And holy crap that's exactly what they got ! CFL and LED are a great combo...

My grow space is 90cm x 90cm and the Pro-Grow 260 is just right. It's advertised for 5 plants, I have 4 in my tent. The guy who makes these advertises realistically, which is more than I can say for most of the other LED manufacturers... They offer free postage to Europe from the U.S. and I think a 3 year warranty ! I sometimes chat with the guy by email, a really nice fella and is always there to answer my questions... I don't think I would ever shop anywhere else. Check out the new X5 LED from them, it's a new model and I would kill for one of them !

When I move apartment sometime and I get a bigger tent I'll get one for sure. I'll keep the Pro-Grow 260 for vegging, I'm never gonna give that light up ;)

So glad you are enjoying the grow, stay tuned for more weekly updates. Let me know if you get in contact with Hydroponics Hut, ask for Benjamin and tell him the Irish LED Logger sent you ;)

Take Care buddy

Hey,

So helped my friend get her grow room started. It's looking great and the little seedlings are just 1 week old by now.

Seriously guys, this Pro-Grow 400 is a demon ! I can almost hear the cells divide in the plants ! The tent is a Secret Jardin 4' x 4' x 7'. Extractors and fans are set up but a better carbon filter will be needed soon. It's an attic grow so fresh air was a bit of an issue but we decided, rather than drill holes in a rented house, we would just leave the hatch open and I brought some flexible duct over to the hatch to pull in fresh air from the house. We will see how things go and if they are looking like fresher air is necessary then hole will be drilled.

So there are 8 plants that will be vegged in about 3 - 4 weeks. In 5 weeks we will know what sex they are and the bad boys will be killed... but not before I get some pollen for my ladies

I'll take pollen from only the strongest males to keep the genes strong. I'm not looking for many seeds, just 20 or 30 for a possible outdoor next year.

So here is her new set-up:

How you doing SL well I like the set up great job. And I decided that because of the limit of my space I will be getting the pro grow 260. Really appreciate the help thanx. — kalidank
