General Cultivation Q&A

Can you use the insulation batts as a substitute for grow wool blocks?

I was kicking around the idea of adding more moms to my closet and was wondering what everyone like to smoke and why. so if could list off favorite strain, or even an every day smoke strain you like. I start us off Black Domina By Sensi Seeds. It has a kick ass "STONED" buzz to it but yields really suck.

...about outdoor grows and I think what you'd call "training"? If I were to have a grow on a balcony that gets a LOT of sun every day, and were to be growing under a wood/greenscreen contraption, and lets say they reached the "top" of this where they bumped into the greenscreen that was "over" them... Assuming they could still get all the sun and water they needed, would they be ok? Also, what would happen, would they just like, start growin' sideways under it? I knew a fellw up north that grew a huge-ass "tree" almost, he tied it over, it seemed fine... So, thoughts?

Has anyone ever had this happen? Bag seed plant. A couple of Belladonna's out side.

hi all i live on a beach and theres heaps of seaweed washed up every day , im aloud to take 20lts a day per person , so i was woundering if anybody has used seaweed as a medium or as a nute for indoor growing ? or does anyone know of any reasons why i shouldnt ? thanks in advance

Ok...so lets say one wanted to grow hydroponically or with airponic equipment... Either. Assuming you worked out ways to contain any moisture/liquid in a seperate area without it "migrating", what do you think would happen if you were to have the roots up above the plant, and plant facing downwards, and underneath it, a grow light on the "ground" under it, facing up? Would the plant start growing upside-down? Would gravity somehow...make liquid/bus size swell more? Would this eliminate/lessen the duration of the dry/hang? I just feel like I wanna do this, just to try...I have no equipment yet, but I think I'm gonnd look further into this, just because. Thoughts?

Hey guys if you guys have been reading up on all my newbie questions you know I am about to transplants my girls to some larger buckets and am almost ready to flower em under the HPS. The question I have is: I have noticed that as the temp decreases where I am residing the plants stems have become a purple color. I can see it in the veins of the leaves a bit but mostly on the the stems. Could this be a consequence of the colder climate: mid to low 60's at night and 70's during the day, or do you guys think this has to do more with a Phosphorous problem? Thanks for the responses and always the massive amount of help. Also stay posted for picks of their new habitat

hey folks, im pretty sure i have either a calcium or sulfur deficiency. as i read in the faq, a calcium deficiency can cause the leaf margins and the leafs to curl in a upward motion. making the leaf's look retarded. i read that a calcium deficiency can come about when too much Mg magnesium is added. Now thinking about it i did add a littl.e extra epsom salts to the soil, before planting them. what nutrients are high in calcium and/or sulfur

If i got a 10" pot 250mm, how high can i veg a plant to roughly or will they stop growing?

Hey guys, I just found your forum. I hope you don't mind, I would like to show you my Aero Space Shuttle. I grew in DWC for a couple of years and got tired of lifting tubs of water so I wanted to have a system with a drain. I designed this aero system for ease of operation. It was pretty expensive, but worth it all, to me. The 6" pvc tubes are 36" long. The grow space is 3'X3' http://i184.photobucket.com/albums/x140/earlon3rd/000_884.jpg There are cross flow tubes to keep the nutes the same level in both tubs. I wanted drains, so i didn't have to do any lifting. http://i184.photobucket.com/albums/x140/earlon3rd/000_0949.jpg http://i184.photobucket.c…
