I bought this chiller/warmer about 3-4 weeks ago on ebay for my little 6-7 gal RDWC, in this other thread. https://www.thcfarmer.com/threads/wise-and-knowledgeable-expert-advise-for-dwc-at-altitude.145565/ So the thing stopped working 1/2 way last week. Half way you ask? It is rated at 180w...

Long ago, in the land of windmills and tulips, the owner of AG Seeds (Todd) and I met. We were both refugees from the "war on drugs" being waged here in the US. Back in those days, 1994, I had the good fortune of being able to do a pheno hunt from some 115+ NL5 x Haze seeds. Most of the seeds...

I'm in the middle of a minor meter crisis, which is better than a minor midlife crisis! 😀 So I dug my old TDS/EC meter out and wondered how the heck and what EC calibration solution to use. I have some, wrong stregnth(?). Start googling and this video came up. According to it, you can mix...

I've been growing my pot in soil for years and have, for years, thought that the leaf 'burn' I always see towards the last half of bloom was a Potassium deficiency, although adding additional 'bloom' fert didn't really help. Fast forward to this winter. The wife and I decided to have a small...

I know it's winter, but 100* temps will be here in Pueblo CO in no time, so time for me to think about water chillers. Since most of these seem to be sold as 'aquarium' chillers, this might be a question for @steamroller. Will the 'compressor' varieties on Amazon/Ebay work well for DWC? I'm...

Recently I was looking at screens, drysift screens, and I ran across this little contraption, The Pollen Extractor. Linked to here. It fits into your fridge or freezer and does a sweet job of tumbling those trichome off the trim and onto parchment paper. It comes with a collection tray, but...

Well, it's been a long time since I made my own personal dry sift, so long that the last time I made some, the e-nail and BHO hadn't been invented. 😲 I've vaped dispensary "bubble hash" and decided to make some full melt drysift of my own, since I've never seen anything like that in dispo's...

I picked up this microscope on Amazon, here. With the 15% coupon, it's only $34. Takes mighty fine pictures, IMHO, for a 35 dollar electronic magnifier. The deal gets even sweeter when you go to the Ninyoon website where they offer you a free "upgraded stand". Well, the one it come with is...

Couple years ago I was toying around with DWC and Kratky, and as I knew nothing about them I started out with leafy green veggies and GH nutes. Yep, kale, spinich, lettus, basil and cilantro. The DWC easily won out. I didn't want to make major mistakes starting off with $25.ea cuttings of...

On Sunday, Oct 2nd, it started out to be an experment with sorting seeds, the float or sink method. I took a bunch of my Finnish Frost seeds sorted into dark seeds, light seeds and control (unsorted) seeds and put them into a 3 glasses of RO water. Not a single one sunk immediatly, but no...

I am looking for new options for my tents climate controller because the new "smart" controller from BN-Link won't control as well as the old 'dumb' model. I am currently using the original BN-Link climate controller linked to here, and the instruction manual for it here. I also just returned...

I know, there isn't any quality comparison between these screens and a set of large, quality, aluminum framed silk screens, but neither is the price. I've been sieving (dry sifting) for decades on the big screens, but love these frickin paint strainers. I originally found them on Amazon, but not...

I just wanted to post some pictures of some trim leaves from this morning and a couple shots from the plant(s) they came from. Hope you enjoy them.

I've been playing around with blackout curtains for those passive air vents in mine, and all grow tents. Here is a link to that thread. I would love to have a set of them tested in a tent with that Apogee light pollution sensor Dr. Bugbee uses and have the results posted here on the forum. If...

You know those screened "vent" openings that have the cover velcro'ed onto the outside of the tent. How do you use them to let air in while keeping light out? I know how I use them, but I'm sure open to ideas and improvements. IMHO, there may be room for improvements in the grow tents we use...

First, you won't see this V5 model on the Dulytek website yet, so here is a sneek preview. (yes, I have permission for Dulytek to post this) 😉 Last Saturday my new Dulytec DHP7 V5 press arrived. THANK YOU for standing behind your product. I had a DHP7 V4 with issues and pictured it beside the...

I have purchased the PPFD Meter app and the UNI-T lux meter with bluetooth to make PPFD maps. If you would like more information on this inexpensive setup, here is the youtube link. These first pictures are of my 'open area' reading. They were taken in my garage with no reflective walls and...

Can LED light ballast be safely run within 10% over their maximum watts rating? I got busy today putting together a new Mars Hydro FC-E6500. It looks like when the model was originally released, it was a 650w lamp. It was apperantly upgrades and now pulls 730w. The ballast is rated for 680w...

Well, I saw this on the Mars-Hydro website this morning. When I searched the site carefully, I found what appears to be the same FC8000 at 2 price points. The only difference I can find between the two are the price and one says "OLD VERSION" at the end. Anyway, smokin price for an 800w light @...

Living soil, I always thought of as alive with micobial activity and seeing mycelium on the top of the insect frass I top dressed with 2 weeks ago under my fungas gnat barrier was somewhat expected. So when I lifted the cover from one of the other pots and saw these wrigglers, I went for the...
