Hey OoNickoC, Not sure what your asking. Flushing a system with R/O and measuring the pH of the runoff is a technique used with soil or soil-less systems. In my case, I am running DWC and I have no soil.   HOWEVER, I have wondered about the influence of the clay pebble substrate (Hydroton) on...

Impressive :drooling:    If I'm correct, you are getting into your "summer" in the next months. I don't know where you are exactly... somewhere in South Africa  :P   Anyway, I looked up some weather info on Johannesburg SA. The summer time high temps don't get much above 80 degF (26degC).   You...

  Hey Biggy.  These buckets of nutes are under two weeks old. I'll be changing every two weeks.   I don't wait very long after adding the pH UP before measuring... maybe two minutes. That's plenty of time for the ions to move around.   Our tap water is runs 3-400 ppm bicarbonate (so 1/3 tap 2/3...

  D3monic.... I can't disagree with measuring at the same time every day. Make sense.   But I am seeing that the pH is dropping consistently. I add pH DOWN every day, and then again every day after that.   I'm hoping that sooner or later the pH will stabilize ... but hoping isn't knowing.   On a...

I have a few pictures of of my wife and I on the Superior Hiking Trail in Minnesota (SHT) from last year. Northern most part of the trail. We planned for 50 miles in 7 days, but we only got 30 miles in 4 days. It was me that failed... or my right knee ! I hadn't work up to this hike. Not that I...

  Hey Spokane, the temps do vary quite a bit in the solution. Prolly from upper 60's to low 70's in the early morning to almost exactly 84 during the lights on period.   I thought that I knew what pH was.... hydrogen ions and hydronium ions and all.  Temperature never entered my mind. I never...

Greetings to All.    I have two separate Deep Water Culture systems running inside of a single 4x4 tent. One of the systems has been a constant chore to adjust the pH (up) from the start (Bhut), and the other system was pretty stable until the last yew days (Reaper). Now both systems need a...

  OoNickoC   Don't know how to highlight your text, but this is a great idea !  Yes this could work for me too, but if I cut into the "finished" product of the LED lamp I currently have, I won't be able to sell it... or maybe I can.   I have no doubt that removing generated heat before it even...

I've asked this before, but didn't get a solid answer.... so as we do we ask again.   I have read that the temperature of a hot pepper plant (above the roots) can tolerate high temperature (90degF-100degF....100+) consistently, but the root system has to be kept cooler in order to thrive. This...

This is not really a question from me. It's more of an observation. I'm looking any opinions.   Grow tents.... fixtures INSIDE.   Two fixtures compared >> An LED fixture (VIPARSPECTRA PAR 700) and a HydroFarm 315W CMh (LEC) fixture.   The VIPARSPECTRA PAR 700 specs show that is consumes 326...

Take my reply with a grain of salt (Epsom Salt)   Don't use Epsom salt unless you have a valid reason to use it. Don't try to prevent or enhance something that "might" happen.  Additives add complexity more than solutions. Just my personal opinion.   Your early pics look good to me, even in the...

Hey Hot Pepper. I appreciate the effort. Thank you !   However, Ads help pay for the site. I'm willing to tolerate Ads... totally understand the need for revenue.... it is the Ads that repeat every 30 seconds or so that completely block me that I don't like. Maybe I can live with those too if it...

  I've read of the Great Lake Agassiz. The lake that flooded our lands after that last Ice Age melt. In fact some argue that the Red River Valley, and what is now the Minnesota River to the South of the Red River is the true source of the Mississippi River. I'll leave that determination to the...

I face a similar quandary... where to go next with the grow tech.   I've looked for information on LED's and it's out there if you have the time to do the research.  It's not at all like buying an MH fixture where you know that it will work. LED's aren't new, but they haven't taken over the...

That visual is excellent !  I tend to like the "tree" version vs. the shrub.  Fewer peppers maybe, but hey, since I'm the only hot pepper lover in my house, a super hot goes a long, long way  :fireball:   Happy Growing,   Jeff

Ditto... let it grow.  Funny but it kinda looks like the Jalapenos I had this year... AFTER a full growing season  :P  Not a great year for me.   Happy Growing !   Jeff

  BHS, One other thing I found out this season is that my container plants (first years for those too) got VERY HOT in the direct sunlight (why are the bags black anyway ??). I put burlap around the pots and that helps a lot, but too late.     AJ, We had a warm spring and a cool summer.  It...

Summer is almost gone here in Minnesota. Forecast for the next week is highs in the 80's (F), but the last few weeks have been lower than the average.    I completely rebuilt the outdoor garden this year. I dug out the old soil which I had installed a few years ago. The old soil was supposed to...

Can't say I have the full answer... but I've heard that 3rd or 4th sets of leaves are hardier that the early ones as far as the sun goes.   What I can say is that I move my plants directly from the indoor grow to the fully sunlit world using burlap as a shade cloth (do not have patients to move...

Hey guested...    From what you wrote it seems that you've been thinking about this project... Good luck to you !!   For the moment I'd skip the fan to exchange the air.  Just leave a vent (not too small) open to allow the O2 and CO2 to exchange. If you can keep the temps in check and have good...
