I used it when I grew in coco and also had fantastic results with it, but being it has molasses in it I would not use it in a hydro setup personally.

I rinse my hydroton really well first, then I let it soak in a container with full strength nutrient solution for a day (ph of ~5.5-5.8) then before using it I rinse it out again with freshly mixed nutrient solution.. the ph will rise badly with hydroton when new. Doing this has helped not only...

I was running my room based off the VPD chart as well but I run a perpetual room, I was afraid of running 75 percent humidity at the end stages of flower.. and my room always has plants in the last few weeks of bloom. Anyone here run VPD in a perpetual room with no issues of bud rot/mold or ill...

Yeah, Hydroguard works great at preventing and getting rid of root rot, so hopefully this is the same, appears to be and like you said 100 x more concentrated.

I found this product which appears to have the same bacteria that hydroguard contains but at a MUCH higher concentration for 1/3 the price. Anyone familiar with this product and is it in fact the same bacteria that is in hydroguard? Contains: 98.85% Bacillus amyloliquefaciens strain D747...

I use hydroguard to help protect my roots from things like root rot and it seems to make the plants very healthy overall. (rdwc and flood and drain setups). Its pretty expensive at ~70 a gallon. I purchased a new gallon and when I got it home I saw the seal was off, was wondering if maybe...

I have another question. How long can I keep a container of pre mixed nutrients for veg and flower? I would like to keep a few brute containers pre mixed (44gal) with air stones. Do any of the additives lose effectiveness after sitting awhile already mixed? Or is it not recommended at all to...

Hey all, I just switched to H16, I will be using it in soil (Potters Gold). I purchased the whole line. I read a few pages back to not use cal mag. Is this correct? I use ro water.. the nutrient line has enough cal mag in it where I won't need to add it? Also is it recommended to use a tea...

I use algen extract which to my knowledge is a kelp extract.

so I would have to add more A or B nutes? I use house and gardens.

mother looks very good and healthy. Problem did not show up until about 1.5 weeks into veg, once they got about 6" tall.. started at lowest leaves first and has started showing up on mid leaves after that. some of the ends of the top leaves have started as well.. but mostly lower and mid leaves.

so its either a ca def or k is what most think?

hey, hydro is best run at 5.5-5.8 ph

Here is a better photo

Click the photo for full size version, upper right leaf has the most issue.

Running hydro, ro water, house and gardens nutes, A, B, root excel, Algen Extract, Nitrogen boost. 5.8 ph. ec 1.2 I am about 1.5 weeks into veg and the lower leaves on some of the plants have redish/brownish spots.. thinking cal/mag def perhaps? thanks!

in a week or two we are getting 6 raptors, 6 1k lumateck digital ballasts and hortilux bulbs, was quoted 3200 from local grow store, seems like a decent deal, we are considering hanging some of the 600's we have vertically too, not sure we will be able to manage heat wise, could add a big window...

I ran 3/4" pvc plumbing from my 44gal brute containers with a 600gph submersible pump. Made an E shape layout in my grow room out of the PVC and put in drippers like others have mentioned. Works pretty well. I have drippers that you can adjust the flow on in case you have some that need more or...

I was looking at the raptors myself, I will probably end up going with them. You think 6 1k's in raptor hoods will work heat wise with a 24k mini split in that room? I am running the 8 600's wings and no problems with heat, max of 81, usually 79 range.

Was not sure if I could do 3 hoods in a row per cfm fan or if 2 is the max I should do, really would like to know how much light you lose going through the glass of a vented hood over using just adjust a wings
