    HELP! Clones in rockwool smell moldy and musty.

    Hey guys, just wanted to give a quick update. I got 100% through! There are doing great now. Letting them dry out a bit really helped as the roots did have to search for the moisture and nutes. One think I noticed was that the roots are very delicate. When I would pick up the cubes to look at...

    First grow, Canna Coco, Granddaddy Purp, 400W MH Veg, when should I flip to 12/12?

    I know that I can start flowering at any time but I would like to get a decent yield from these. I've read that Granddaddy purple doesn't stretch much so if I start flowering now after 3 weeks and 6 inches in vertical growth, will I have a small yield? Does anyone have any experience with...

    First grow, Canna Coco, Granddaddy Purp, 400W MH Veg, when should I flip to 12/12?

    WHEN SHOULD I SWITCH TO 12/12 BLOOM? I want to do a SOG but I don't know if it's possible with GDP. So Here is my setup: 10'x10' room with a small closet. I built a dividing wall to have a separate veg room. My veg room is approximately 5x6 because it is using part of the closet. Bloom room...

    HELP! Clones in rockwool smell moldy and musty.

    So I've got more yellow leaves now. I'm using the Clonex Root Solution to water them. Should I be cutting these leaves off or should I "leaf" them alone?

    HELP! Clones in rockwool smell moldy and musty.

    Okay so that makes sense. So seeing them wilting this morning was a good thing? Should I not have watered them? The cubes still had a little moisture to them but the plants looked pretty sickly. How do I know when they've gone too far? Should the cubes be completely dry? When I water them...

    HELP! Clones in rockwool smell moldy and musty.

    So the yellowing leaves are okay? This morning I noticed that there are more leaves turning yellow. The cuttings didn't look so good this morning at all. I told you all that I had put a 40w bulb inside the cardboard box under the tray to warm up the cubes. Well the cubes were pretty dry so I...

    HELP! Clones in rockwool smell moldy and musty.

    Ahhhh...what's that you say? Don't squeeze my cubes???? Too late. As you can see from the pictures, they're pretty much squeezed to shit. Shortly after the strangling, I read the same thing you just said. It actually causes the rockwool to lose a lot of it's ability to retain air so that the...

    HELP! Clones in rockwool smell moldy and musty.

    I actually go the cuttings from a friend of mine who got them from a friend of his. LOL... So I don't really know if he soaked them or not. I gave my buddy the rockwool and the prop tray and a few days later, I had clones. I'm going to take photos tonight and post them. Last night I...

    Homedepot Duct Boosters

    I agree. I'm completely new to this but I went out and bought a 4in version (from Home Depot as well). It has an 80CFM rating so I bought it for my veg room of 180cubic ft. It works okay to pull the air out but it really hasn't cooled my space at all. My space is pretty air tight so it helps...

    How to best calculate CFM?

    Thanks for the suggestions! I'm lucky enough to have a good sized space to work with. The space is a little under 10'x10'x8' and there's a small closet that adds another 4.5'x3.5'. I'm going to run a 22 sq ft (180 cubic) veg room (will keep a momma or 2 in there as well as a shelf for my...

    HELP! Clones in rockwool smell moldy and musty.

    I've got the hood cracked open a little to allow more airflow already and I have a fan pointed at the box too. Just did that last night after I smelled the funk. The guy at the hydro store told me that I need to keep the vents closed and that opening the hood 3 times a day to mist should be...

    HELP! Clones in rockwool smell moldy and musty.

    I a newbie. This is my first grow. I was given some GDP clones from a friend 3 days ago. They were all in Grodan rockwool cubes and they are in a tray with a hood. I'm using Clonex clone solution. When I first received them, the cubes had so much water in them that when I squeezed the...

    Understanding CFM

    I'm new to this and this is my first post. This is something that I've been searching for all night. Some sites say 3 - 5 times a minute and others say once every 3 - 5 minutes. What I don't think anyone else caught in reading this link is that it says if you are only trying to replentish co2...
