I snapped some pics of my outdoor ladies, hoping someone can tell me whats goin on with these new leaves. For the past two weeks or so, they've been growing very purplish/pink leaves at the very center of each bud area, but no signs of buds yet. Maybe some sort of deficiency? Or starting to...

So I'm trying to force an early flower with two plants that I just moved outdoor by giving them bloom nutrients. Will that be enough? Or will they let the sun dictate when they flower? They're both in dwc buckets, if that makes any difference...

So, i had a few plants that i started under a T-5 and veg'd for about a month. I had the feeling they weren't gonna be huge producers, so i decided they'd be the perfect plants for an outdoor DWC experiment. I don't plan on using a chiller, so i buried the buckets to keep them cool. Only 3...

So, after i just installed my 8" exhaust fan, turns out my 6" intake can't keep up...not even close. I'm thinking my intake needs to get stepped up a bit, but i'm a little hesitant to cut any bigger holes, given that it's cold here 8 months out of the year. Any wisdom on this subject from...

I just bought an 8" exhaust fan, but i'm trying to figure out where to put it based on noise. I know there are a lot of factors, but typically, do exhaust fans sound as loud outside as they do inside?

So, i'm setting up my new grow room, starting with HVAC. I have no idea what I need other than an 8" exhaust fan, carbon filter, and roof vent. Anyone ever punch a hole straight to the roof? What else do I need? I found some flanges for drywall, but I have no idea if I need that or not. What...

I noticed the air pump i use to aerate my DWC buckets has a 3/8" valve on the intake. So i decided to run a hose from the intake to outside, so i can pull in fresh air through the pump and up through the airstones. I didn't have a ton of fresh air coming into my grow space before this, so i...

What light cycle are you supposed to use for seedlings that are roughly 1" tall? I have them under a T5 fluorescent and have been doing 24/7 light, but i realized that might be incorrect...I used fem seeds, btw.

I planted a bunch of seeds in rockwool and put them in a propagation dome to sprout. I checked on them constantly and all of the 22 seeds sprouted, but after 3 days, i noticed an odd mildew smell when i opened the dome. Apparently i didn't give them enough ventilation and one of them actually...

So i planted 4 seeds that popped in rockwool. 2 of them shot out instantly, the other two have dragged their feet to get started. All 4 of the seeds popped prior to my adding them to Rockwool. In the pic i posted tho, the seedling on the left is leaning over pretty far...almost laying down. What...

Ok, so i have germinated some seeds and after they popped, i put them in rockwool cubes (rockwool was soaked in 5.8 PH water). They're now in a propagation dome with a heat mat under them. My question is, when do i need to put a light over them?

So, i put my seeds each in shot glasses with a tiny amount of water in them, then covered them and put them on top of my receiver. I noticed this morning that each one of them has popped, but the white tail is just barely showing. When should i move them into rockwool?

Hey RIU, i know this may start a war of opinions, but i'm about to start a DWC setup and i'm wondering what the most successful and easy way would be to clone prior to start in DWC. My currrent plan is to start in very small rockwool, so that the roots have a medium to take hold in, but i don't...

Hey gents, i'm just trying to figure out a couple last details before i start my first grow, so i'm hoping you guys can be of help. 1. I'm going to grow 2 different strains at a time with 8 plants total under 2x1000watt lights, but i don't know if it'd be better to run one Recirculating system...

So, i'm trying to plan out a grow room that will harvest every 2 months. Here is a pic someone on the forums created for me of my grow space: I'd like to run a scrog in the flower room, but if i'm veg'ing in a separate spot, then moving them into the flower area, will that make it difficult to...

I'm trying to design the section of my room for the clones, but i'm not sure how close my HO T5 should be? Just hoping someone with some experience with one can tell me what kind of heat i should expect...I don't wannt cook my starts ;)

So, i'm running a 240V 65amp feeder cable(four copper wires: two 6 gauge hot wires, one 6 gauge neutral, and one 8 gauge ground) from my main panel out to the sub panel in my grow room. Here's what i'm planning to have on my sub-panel: 30amp breaker for 240v circuit 20amp breaker for 120v...

Ok, so as i have read many many posts on here about different ways to design a grow room, i want to see what the experts say about possibilities for my situation. My grow room is a blank canvas at this point. I have bought zero equipment thus far and i have done no modifications to the grow...

I'm completely new to the grow game and i'm trying to plan a grow room. I have a 280 sqft shed that i just rebuilt. New siding, insulation, etc. It's built as solid as a house. I'm trying to use it as primarily a grow space, but i'm really unsure of a few things: I live in the Northwest, so...

So, i am taking the plunge into the growing realm very soon. I'm looking at having a dedicated 150 square feet for grow space and i'm thinking 10-12 plants in a circulating DWC setup. This will be in a finished shed (insulated, drywall, etc.), but it won't be hooked up to heat. I'm new to this...
