Hello, I'm wondering if you'd be able to go over to my thread in growroom design and take a look at my new aero design. I'd appreciate it and will rep all who deserve it. Thanks, AeroKing Please, Click here for the thread.

Please critique my design. +rep for any decent input. This is my plan for a new aeroponic system that I'm soon going to be building. It is two stories, being retrofitted into an existing grow box. The boxes are going to be the "Tough Boxes" that you can see in SOGs journal. All white lines...

This is a tutorial on how to use a simple, built in feature of Google to effectively search Rollitup. "All too often Newbies and Vets alike will try the sites search engine and come up short handed, even though there are many related posts and threads in the database." It's unfortunate, but...

Before I plunge into buying this model of LED, has anybody used them? I'd really like to know if you'd think that 2 of these will work for an area 2.5' x 3' vegging clones through about a 12" lollypop.

Well, I've been trying to decide whether to use LEDs or high end T5s for my new veg box. I think I've decided to use 2 x 45w GlowPanel LEDs per unit to cover roughly 2.5' x 3' of veg, starting from clones, leaving the box as about 12" lollypops. (If I have to, I could add a couple T5 strip...

I'm setting up a veg unit for a perpetual operation. Will consist of a wooden box 3' x 3 1/2' x 7' tall. Ill build a shelf half way up and stack 2 DIY aero cloners in here that will double for the veg and first couple transition weeks of flowering, then they will be thrown under hps lighting...

The primary benefit of vertical growing is that you take advantage of 360' around the bulb, and the floor below, right? So, for the many vert setups that use 2 bulbs, are you not counteracting this benefit by having the light between the 2 bulbs being wasted? Shouldn't all vert grows be done...

I'm thinking about taking a trip to a cannabis friendly country to sample some new genetics. I've heard that the majority of coffee shops in Amsterdam are going closed/going to close soon. I've heard that in Canada, the coffee shops don't actually sell bud, just let you smoke. I'm...

Does any one have advice on pruning method that can help maximize the amount of clones able to be cut. More info and pix available if needed. Thanks in advance.

I need help optimizing my rain forest veging box I am using my rainforest66 for Vegging my 5 week old Nir B-52 79-87F in 3x3x6 box, humidity is 50-40%(a/c on order) 400W MH and 4 100w eq 5k CFL, Lighting is 18/6. Distilled water(switching to R/O next flush) GH micro, gro, bloom (3:2:1)...

Is this odd? they are nirvana b52 and slowly growing, 3 weeks old...

These are about 3 weeks old. Tips are browning in spots, and curling. Growth seems stunted , new growth is deformed. I think I have a nute deficiency. Any one with experience please comment 78-81F in box, humidity was up to 80%, now down to 45-50%. 400W MH and 4 100w eq 5k CFL, Lighting...

These are about 3 weeks old. Tips are browning in spots, and curling. Growth seems stunted. I may have had the light too close (18") for about 16 hrs at one point, about 4 days ago. 78-81F in box, humidity was up to 80%, now down to 45-50%. 400W MH and 4 100w eq 5k CFL, Lighting is 18/6...

I've read that you are to begin feeding nutrients when the plant has it's "first true set of leaves". Does this mean the first 2 jagged leaves (that show up right after the cotyledons) or the first leaves with their own stems? I'm seeing yellowing edges and brown spots on the leaves of my...

I've seen people using aero/hybrid systems without the cocoliners (just drop the hydro-ton in the pot), but I'm worried that any dust that doesn't get rinsed initially will clog the mister heads. Has anybody ever experienced a problem with this? Or any comments to set me on the right path?

Maybe I'm just being paranoid, but I'm in day 6 of germinating Nirvana's B-52. Of 10 seeds, 4 have popped, 2 on day 4 and 2 on day 5, none today. I'm using the damp paper towel in a bag method on a heating mat (~82-85F). I don't recall ever having seeds take so long... (it's been a while since...

I'm contemplating adding an inline ultraviolet filter to my Aero-hybrid setup. Probably placed right before or after the chiller. Thought: prevent any possibility of contaminate buildup in the res, therefor prolonging necessity for res changes. (BTW, RO-DI water being used w/ GH liq). 2nd...

I'm thinking about building a small germination box incorporating blue-only LED lights. Will all blue lights be OK for this, or do I need to mix some red into the spectrum as well?

What color light spectrum is best for young seedlings? I have heard mainly blue but some red will help. what is better LED or CFL?
