My RO water comes out at 7 pH. Both my old RO system and my new RO system outputs 7 pH water. Which makes it all the more confusing for me trying to pinpoint what exactly's happening (I currently have four buckets of four different water sources and I mixed in Jack's and am measuring pH as time...

damn, wish i could use tap water and bypass having an RO system. Wouldn't have to drain so much "waste" water. But my tap water comes out at 500ppm here in socal

I got a new RO Filter a year ago. I just realized recently that it might be the reason I have been seeing my pH drift up so high. With my old RO filter I would mix up my Jack's mix and it would come out to 5.8 on the dot every time. My RO water was 50 ppm so I thought it would be beneficial if I...

So I should just start adding epsom salt to all my Jack's mixes even though I didn't have problems without epsom salt in the past? Not like it won't hurt to add, correct? Going to mix up a res now

Hey guys, I have three plants sharing a reservoir of Jacks+calcinit and all three are showing showing signs of stress. I've been using Jack's hydro for a couple years and never had problems like this. All three plants are sharing the same reservoir so I'm guessing it has something to do with the...

Thank you for pointing me in the right direction! Will ask there

PPM is still sitting at 600-ish. I dont remember what it was exactly but i aim for 600 to 650 ppm usually. They definitely look hungry to me thats why im posting this.. just not sure why they're hungry or what they're hungry for.

Yes exactly. It is not root bound. Roots hang out the bottom of the cup into the reservoir below. They are white and healthy fwiw

I have three plants sharing a reservoir of Jacks+calcinit and all three are showing showing signs of stress. Last week I had discovered the pH had shot up to about 6.8 and I brought the pH back down to 5.8 and it is currently at 6.0. The nutrient solution consists of 600ppm of Jack's 5-12-26...

Hello, I have a 6.5' x 6.5' grow tent to dedicate to flowering. I am in the process of buying the lighting which I want to be quantum boards. I was wondering if i should fill the tent with 240 watt boards, 320 watt boards, or 480 watt boards? and how many? I was originally thinking of doing...

i read that those two diodes are EXACTLY the same though. and that the only difference is the H just stands for HORTICULTURAL as samsung intended to market it to the horticultural demographic by changing the name to LM301H

thanks for the insight! I am planning to order eight 480 watt fixtures actually. Hope that's enough to qualify for some type of discount. As far as asking them to match/lower pricing based on another board I think I will just show them the Meiju version of the kingbrite board im looking at? I...

how does one negotiate on pricing with KingBrite and/or Meiju? CONTACT SUPPLIER on the alibaba page? In need of 4k watts worth of LED lighting and need to pull the trigger ASAP!

Hello, I'm in the market for eight 480watt Quantum Boards for my flowering room. I remember reading in the past how customers have been able to negotiate on pricing with alibaba store representatives. Can I get some tips/advice on how to go about negotiating? Like do I just go to the alibaba...

yup, got a mini split in the room to keep things cool. would you suggest a different lighting arrangement for a 6.5'x6.5' tent? or do 4 480-watt boards sound ideal?

hey guys i have a 6.5' x 6.5' grow tent i need filled with quantum boards for a flowering tent. Since my tent is square shaped, 42.25 square feet, and I'm aiming for 45 watts per square foot I figure I could get four 480watt boards to get exactly 45 watts per sq. ft. Does this sound like a good...

okay you guys are lucky i just happened to catch the thread title COSTOCHONDRITIS and thought to myself wtf is this doing on this forum?? I had costochondritis last year and fully healed from it in about two to three months I think. I believe I got it from coughing so much and so hard when I...

Dear fellow Hempy Bucket user, I believe you!! I, too, consistently grow plants that yield a whole pound off of each plant and I don't even consume a single watt of electricity!!!!!! :cool: Post pictures or it didn't happen!? Oh, it happened alright... My Proof: (that's a hempy bucket in...

has anyone tried both More Cowbell and Space Cake? Undecided between the two. Both are Forum Cut GSC females but different dads? Snow Lotus and G13xHP dads which from what I read are probably his most popular dad crosses, along with appalachia. Would appreciate some insight!

Hey guys, after 3 years of growing I've finally run through my Goji OG and SSDD seed packs and although I got a couple great phenos I didn't manage to keep any of them :cry: I'm currently in early veg with some Hollyweed seedlings and want to buy some more seed packs for my upcoming grow. I...
