The time of year that it is and the climate I have makes it pretty easy to keep my drying room within a very tight range. Using a heater with a digital temperature controller and a humidifier on a humidity controller is allowing me to keep the room between 60-62 degrees F and 59-62% RH. My...

I'm wanting to put on/off switches on all of my drivers. Each driver is powering (2) Quantum Board QB288 boards wired in series. My drivers are outside of my grow space and I would like the on/off switches installed in my grow room. I don't care too much what style of switch I get, but...

I need a new pair of glasses while I'm working under a bunch of quantum boards. Can anyone suggest something?

This is probably going to turn into a lengthy discussion but I would like to 1st discuss an obvious problem I am seeing. Maybe I'm missing something...I don't know. Bit of background first - I've always been a bottled nutes guy but I've spent the last two months reading as much as I could to...

I'm still designing my first automatic watering system and I don't fully understand a few topics. I put together a simple mockup and am hoping for some feedback and knowledge. My reservoir will be between 1 and 2 feet below the height of the main line, depending on the level of the res. I...

I'm looking to build my 1st automatic watering system and am hoping to not make any big mistakes. Here is the room: I placed red marks to indicate approximately where the (12) manifolds will go: Am thinking of having an air bleed at the end of the line. 3/4" PVC ~93 plants in 7"x7" pots...

Hey everyone, I just got the results back from a water test on my well water. I'm hoping someone much more knowledgeable than me can take a look and point out anything of interest or concern. For the last few years, I've been creating my own RO and using an 80/20 mix of RO to well water...

Hey, Looking for some recommendations on a brand or supplier of clean, well rinsed coco coir. I've tried many different brands and none of them are what I would consider clean. I don't want to go through the rinsing process so if there are clean options out there, I want to try them. Thank you

Welcome! All of my work thus far has been scattered across multiple journals and it's a bitch to keep track of it all. I now present Hot Diggity's Lab. An assortment of ramblings, experiments and the occasional stroke of luck.

I'm looking to dip my toes into the world of breeding (pollen chucking). I've got 5 different kinds of seeds that I want to make crosses with like so: Panama Female x Panama Male Panama Female x Guava Wookie Male Panama Female x Chemdawg Male Panama Female x Sunshine Daydream Male Panama...

Hey, I just finished up with my grow and I want to run a few experiments on cure length. I would like to produce samples that have cured for: 2 Weeks 4 Weeks 2 Months 3 Months 6 Months 12 Months 18 Months Here's the challenge: Once I have a sample at my desired cure length, I need to store...

Has anyone experimented with reducing the length of a day from 24 hours to say...22 hours when flowering? Seems reasonable to think that we can possibly get enough photosynthesis in 10 hours and preserve the 12 hour dark cycle. Just curious, really.

I suspect this might be a Mg deficiency but I wanted to run it by you all. My grow has been trouble free thus far until I saw this tonight right before lights out. What you will see in the picture is only on 4 branches of a fairly large plant. The issue is on the top most fan leaves only...

Is there a trick to disconnecting wires on a Quantum Board? I don't want to break my board and the wire does not want to come out!

I've been away for a few years and am happy to be back. For those of you who followed my previous work, this will be a dramatic departure from my typical sea of green adventures. I will be starting off with between 3 and 6 plants and will pick the best one according to appearance and smell...

Does anyone have any experience with running a legal grow room using vertical bare bulbs? I'm putting together some design proposals and have some concerns about what might pass for "code". Any insight at all would be very helpful. Thanks!

Hey everyone, I'm building my 1st LED light and was wondering what everyone's thoughts are when it comes to grounding the heatsinks. My light will consist of (4) heatsinks and the picture shows the 2 outer ones. I'm not really understanding why the heatsinks/metal frame would need to be grounded.

Hey, I've been growing for a little over a year now and I have Well Water. I decided to get my water tested to find out exactly what is in it for the purpose of possibly mixing my own nutrients custom tailored to my water. At any rate, here are the results: Is there anything on here that...

Hey everyone, I run a chiller on my 27 gallon RDWC setup and keep the water temps at a stable 68/69F. I use well water and the temps of the water coming out of the ground gets progressively colder as winter comes. In addition, my grow room temps drop and will get as low as 49. I'm looking at...
