Your ventilation should be enough for a PC grow box.. don't get too fussed about the rpm etc. With those two fans and you opening the pc every now and then to look at them will be enough air circulation.

If I had it my way I'd go straight for it. Unfortunately these products are near impossible to find where I am, and my grow isn't anything too flashy.. just looking for something that will help my plant grow healthy and won't kill it in the process. Just found this..problem solved?? Once...

There are lots of different seedbanks that breed the white widow strain with different characteristics. Most of the ones I've personally seen finish flowering in 7-8 weeks. I have the seedsman white widow seeds germinating as I type, website says it finishes in 8 weeks.

I have a built-in magnetic ballast in my 250w MH Lobay light fixture (my mistake on my earlier post where I said my 250w MH works fine in my 400w Lobay, its actually a 250w MH Lobay). Will a 250w HPS work on this 250w MH ballast??

Saw this plant food in my local garden shop. Considering using this as nutrients for my soil grow during the vegetating phase as it is affordable and easy to get. I've heard plenty bad things about miracle grow products so I've been staying away from them. How does this one look? Anyone with any...

The ph problem probably is why its looking a bit stretched and not as bushy as you'd expect from keeping it 10" under a 400w hps. How long was it vegged for?

How long are you planning on vegging for before flowering? That cab is quite short and height can quickly become an issue..

Interested in this too.. tried the wet towel, inside a small 1.5' x 1' x1' seedling box. Only got the humidity up from 30 to 35%, before it dried out about 2 hours later. This was with a cup of water sitting around too. Anyone with a more successful idea?

From what I've gathered going through these forums there's not much difference. Longer daytime = more photosynthesis, but some also say that a few hours of darkness helps with root growth. Also keeps electricity costs down if that can become an issue, and also cools the grow area during the...

Yeah that's great advice for someone that's started a thread for opinions on a HPS system he ALREADY has. Not that 2 x 11w CFLs will much use except for maybe getting seedlings a few inches tall and keeping them warm. Tweezy what are temperatures in the cab with the light on? I've got a 250w MH...

Lowryders do grow fast but even so, 70w will only be enough lighting for a few weeks and won't be enough for vegetating the plant to anything considerable. Even for a small budget grow, I'd say you need at least 150-200w of CFLs a plant. Sorry to be the bearer of bad news but 70w will get you a...

Nice short and leafy. What lights, soil and nutes are they under?

Using clear cups pros and cons pros: - you can check on the root growth as you can see through the cup - you'll have a better idea as to when to transplant into a bigger pot - easier to tell how much moisture there is still inside the cup even when the top appears dry cons: - roots don't like...

If you want something to just plug into the wall then go for CFLs.

looool I have my own grow bro, check it out sometime. Just curious and wanna help like the rest of RIU.. paranoia is a bitch though I feel ya hehe

My seedlings are about a week old. One's growing well and is almost an inch tall, the other.. not so well. I'm guessing it could be due to heat stress now after reading about yours, as I've had temperatures around 84/85, sometimes peaking at 87 with the lights on, and humidity is extremely low...

I've heard these AKs can easily double in size during just their flowering weeks so you should transplant to at least 3 gallon pots for them to reach their potential size.

One of the buttons at the bottom when you make a post will say "Manage Attachments". Attach away..

How long did this one veg for before starting to flower? Looks awfully young!

How big is the new container? How big are you planning on letting it veg?
