So I'm compiling a list of parts needed to create adequate ventilation in the grow tent I'll be purchasing and decided to try and design what it should look like. Here's the tent I'm looking at purchasing: Here's the design I constructed although I'm not too sure if it will suffice: The...

So I haven't been on RIU in a while and rarely post, (I'm a chronic viewer) but I've decided to embark on a new project and I'm looking for some input. I'm going with a 8' x 4.5' x 6.5' grow tent, attempting Al B Fuct's approach at harvesting every 2 weeks. The goal is to create this setup...

Alright so I have another day or two until the res needs to be changed and over the past week I have noticed that my babies are experiencing some problems. The first picture is a leaf off of a pure sativa and the second leaf is off an indica. The temps range from 87 - 67 day and night. They...

Anyone ever tried the automatic blueberry from lowlife seeds. Dr. Chronic has it right now and it says it is new but haven't seen anyone that has talked about it or anything...Any ideas or input?

I took them 2 days ago and I have them in a decent sized glad container... should I keep them in there as a humidity dome or just let them be without the lid under the MH?

I meant the amount of light.. based on what pullin said, I might just get a couple of fluoros to keep the mothers vegging for a while...

What about a 400W MH, just keep the clones about 3 or 4 feet away? Which would be more productive?

I just took several clones and was wondering if two 75W incandescent bulbs and a 35W flourescent bulb would work. I know the incandescent is the wrong light spectrum, but they work fine for starting seeds so I assumed it would be similar with clones... suggestions...?

Title says it all, I just took some clones from some bag seed plants that I have growing. My objective is to find which ones are female and keep two strains that I like. I was just wondering how much light a mother plant would need in order to stay alive vegging? Thanks

Here's a link to a light chart for several light, hope it helps! ok so whats the deal on using hps and mh? - Cannabis Culture Forums

If you're gonna foliar feed, you should either raise the light or just spray them when the light goes off... I did the same thing and had a burn spot.. that's exaclty what that looks like.. best bet would just foliar feed once the light goes off, they like that

When you plant your seeds in the rockwool, do you ever soak the rockwool in a ph'd water solution 24 hours prior to planting them... If I remember correctly, you should soak them in a 5.5 ph solution 24 hours before planting the seeds. When you soak rockwool, you want to shake off any excess...

I would just let them grow under the 600W hps.. Although side lighting is always a good idea so that the lower branches and bud sites get more light.. I would say invest in a MH for vegging rather than adding side lighting.. I'm actually starting a grow and noticed a big difference in growing...

Alright, it seems like the plants perked up a little over night once the temps got a little lower. I have a feeling the humidity/ temperature in the room is getting a little excessive. The little ones that I put in with the older ones seem to be drooping a lot more so I think I might have to...

Well I moved the light about 1 1/2 feet away. I'm not too concerned with the curling as it is not too severe. But the drooping is puzzling... I just read somewhere that the temp. in the res. and root area cannot get too hot. I'm starting to think that the bigger light could be making the res...

Hey guys, I just upgraded yesterday from using a little 150W hps to a 400W hps. I had the light about 10 or so inches from the top of the plants and everything seemed fine. Then I went in to check on the my ladies about 2 hours later and noticed that they were starting to droop. The leaves...

Those ladies look awesome man! Did you use the hps all the way through? You should try aeroponics next!

Nice plants for a first grow man, how long are you gonna let em veg for?

Hey I'm fairly new to this forum but have grown a couple of soil/dwc crops. I was wondering how everyone mixes their nutes in the reservoir. I'm using Holland Secret 3 part nutes and it says to always add the micro first. i've done a lot of reading and after seeing people just randomly add...
