    IF you are new to LED and want help choosing what to buy, POST HERE!

    Always interested when I hear people bagging on chinese lights. How do you know the expensive companies aren't getting their lights from china? I'm sure you know most components are made there... I am concerned about scammers, but I'm sure some chinese lights are just as good, and cheaper due...

    og gth#1 stretch before flower

    I have six og gth #1 which I grew unfortunately in 2 litre pots for 2 months before transplanting to 9 litre pots (biggest size I could fit). I topped on the 2nd true node and again for 4 main heads which stretched alot before transplant. I cut around the sides of the pots and pulled basically a...

    Early sexing, breeding, feminised seeds.

    Its not that simple. Its been about 2 months of veg now and still no sign of sex, they are still in 2 Litre containers (shocking I know) and they have stretched quite a bit. I need to transplant them now but I was hoping to identify the males so I could keep them small by leaving them in small...

    Early sexing, breeding, feminised seeds.

    I have 6 plants that I need to determine sex so that I can transplant all the females and leave one male for regular seeds. I also want to use colloidal silver (I know how to generate it) and make some feminised seeds also. The problem is I don't want to pollinate all the females, but I need...

    micronutrient overdose?

    So I checked the runoff ph and it was very yellow - around 6.0 maybe lower even (hasent gone red yet). I've "flushed" with normal rainwater (ph is high around 7-8) for about 2L runoff for 6 plants in 9 litre pots with 50/50 soil/vermiculite mix. But the runoff is still yellow like it hasent...

    micronutrient overdose?

    I have just completed my second week of vegging. I have been using superthrive and growzilla. Two days ago I also bought some nitrozyme and earthjuice microblast, I added the microblast to the nutes and foilar fed the nitrozyme and added some ph up cuz it was around 6.0-6.5. But now I see that...

    Topping the 1st node for mainlining (without clone)

    Well you would basically expect it to be double the size woulden't you? With one large cola instead of two smaller ones? Is it about the same size if you stack the colas on top of each other? I thought the idea behind main lining was that you could grow multiple large colas at a time, making the...

    Topping the 1st node for mainlining (without clone)

    I am really hooked on the idea of main lining, from the main lining thread. I've read most of it through so I know my way around the technique. However there is still something bugging me about it and I know many people have asked the same thing: "Why not just top at the 1st or 2nd node...

    Arduino Controlled Grow and PC Program - Work In Progress

    This was exactly my idea. I wanted to use the same arduino board to measure temp/humidity/ppm/ph/co2, even perstaltic pumps to make my own dosing system. Even wanted to use heat equations and extensive data logging, such as nutrient use vs co2, temperature etc. I wanted to have it so that if the...

    LED vs HPS again... pre-experiment.

    Over the past 3 months or so I've been extensively researching the LED story, from the claims of LED salesmen to the great controversy surrounding them and their efficacy. So here is my breakdown of what I've learned so far (in order): The first LEDs were really bad, stay away from the low...

    Top and FIM analysis

    So the only place new branches grow from is between other branches?

    Top and FIM analysis

    Some people are saying Fimming is the same as topping, so you mean that it stunts the growth in the same way as a top? Allowing lower branches to grow more? I've heard of cutting straight through a node and getting more than 2 tops splitting off from it can anyone confirm this from experience??

    Top and FIM analysis

    I know topping creates two tops, and fimming creates two or more... but what is the actual reason behind this? It seems that every new growth is actually three "shoots" and that topping the middle growth simply redirects it to the adjacent growths, resulting in two instead of three "shoots". If...

    12/12 from seed vs plant maturity

    Well this will be my first grow technically... I'm a bit confused about the triacontanol and solublizer polysorbate 20, where do you get them? Are they included in hydro/additive products or are you just taking horticultural experience and applying it to marijuana? Seems if these solutions...

    12/12 from seed vs plant maturity

    I don't like the idea of root pruning as that seems to lean on the side of stunting growth. Thanks you just piqued my interest in using chemical plant additives. HPS seems to cause the most stretching I've seen... Im going to use LEDs to stop stretching and HPS for flower. Please elaborate on...

    12/12 from seed vs plant maturity

    YES! I agree not to meddle once buds start forming... thats the time for all the stress theyv endured to pay off, and they can enjoy their path to sinsemilla in our artificial sunset.. But I don't understand what you mean... whats "the way its been done"? I just said I am going to give it 3...

    The Main-Lining Thread

    I really like this "main lining" technique so far.. not only is this subbed but im making it a bookmark :D The only thing I don't like is the constant chopping of new growth :( such a waste of energy.. Does the growth between where the first node splits ever stop growing? Otherwise it makes it...

    12/12 from seed vs plant maturity

    I know, its scary, I can just imagine it limping over and never getting up again. I might just do it to a few and hope they survive. This is just a seed run really... I hope the seeds produced by minimal vegging don't alter the flowering time genetics or something lol... Ok this is my secret...
