My plant is healthy now, but when it was younger I had PH problems, therefore I don't know where the actual FIRST true node is.. I'd like to try uncle ben's topping technique (topping between the 2nd and 3rd true node) but I don't know if I can do this now. The plant is doing great and the...

I have no clue what's going on, I've had two successful grows and this has never happened to me, the only thing different about this grow is that I'm using a 400w HPS to veg instead of CFLs... What's the problem? Information: Seed planted 4/8 Sprouted 4/11 (10 days old now) Watered when cup is...

Do you HAVE to have an auto-flowering strain or can any flower if you give them 12/12 from seed? Also, if I veg and flower with 400w hps what will the effect be on my buds?

So, it was time to move the seedlings closer to my lights. After moving them, my surface-of-soil temps shot up to 90.. What's a good cooling method for this? It's in a rubbermaid box setup, one intake at bottom and an exhaust at the top. Had been keeping things VERY cool before, but now that my...

The attic is ver cool and has a very high exhaust vent. Luckily the people who designed it used very thin sheetrock for the roof (with large gaps between studs). So, RIU, what do you think? Bathroom exhaust fan with a carbon filter at the top of my growroom is enough? If you had an easy access...

I've decided to go with them. Is shipping discreet or do I need to ship it to a "special location" ?

I want to buy a 400w system with hood and ballast. Please recommend one. +rep and MANY thanks. I would like to spend a max of $150 if that is possible.

I understand why you would use the organic vs. the normal MG potting soil due to the nutrients, BUT, do you add perlite since it does not contain any? Or is there some sort of aeration/absorption organic content to replace this?

I've recently been able to build a seperate room for growing so I no longer need to be confined to my rubbermaid setup... unless it'd be better. Which should I use? Veg mylar room - (4) 40w Fluoro 4 footers or Rubbermaid CFL & mylar - (6) 26w 6500k, (2) 42w 2700k

I've got (4) 40w 4 foot fluoros in a 3x5 grow room lined with mylar. But, I also have a rubbermaid growbox setup with (6) 26w 6500k and (2) 42w 2700k. The growbox is a mere 3x1.5x2 and it is lined with mylar, so it contains more concentrated light (According to my light meter) Which should I...

[Cliffs at bottom] My soil is a healthy PH 6.5, but shows VERY LOW for n, p, and k. My question is.. I know everyone here says you shouldn't fertilize seedlings (seedlings being plants focusing on root growth rather than obvious foliage growth) because they have enough npk to support themselves...

I know of using d. lime for raising it.. but how do I lower it? Mine is 8.0 :( alkaline

I just fimmed between the 2nd and 3rd node, and the little growth (the small stems coming out of the 2nd node forming the new smaller leaves) I cut off one side.. Is my plant going to die? Is this going to affect my FIM? Will this lower my yield? Also, the clone is already very wilted, what is...

My prime plant who is doign beautifully is just forming it's 6th node and I have enough foliage below the second node to be comfortable enough to FIM. My question is.. do you only FIM plants you plan to flower or is there a benefit to FIMming your mothers? The reason I ask is because I want...

2.5 weeks old.. has 4 nodes (i think.. see pic). it's about 3.5" to 4" tall. Can I fim it now (between 2nd and 3rd node) or do i need to wait?

Too early to tell? Also, how many "nodes" does this have? I count 3 (4 if you count the newly growing one). Is this right?

I was looking at one of my youngsters nodes and I noticed two little protrusions. Not knowing anything of plant anatomy, I assumed these were tiny branches soon to form. But, I decided to look online and I've come to believe they are the "stipules." What is the purpose of these? Does it form...

The bottom fan blows air in, the top fan blows air out. In the picture with the black drainage grate, it is hard to see, but it is a small tub of water with a sock hanging into it for a humidity wick. All walls/floor/ceiling are flat white. (2) 26w CFL 2700k (6) 26w CFL 6500k I will put 4...

Is scrog the same thing as the "spiral" training I've heard of? If so, am I doing this right? I bend the stem over and allow it to grow back up to the light (stem bends and makes a SORT OF L shape). See pic. Is this a good start? Or do I now bend it in a different direction? Wish search worked...

When I transplanted this plant, the roots (only around 4 visible ones; all white and hairy) were hitting the bottom of the pot. This plant has always been small and pale, but I figured it would get better, since my main plant is doing good other than nute burn (I think) Plant 1 Very light...
