Hi all, For a relatively small setup (say 2.5KW of lighting) and assuming the same yield, how much more power does a closed loop setup use vs an open loop setup? Obviously the main extra draw in closed loop will be the AC unit. cheers.

Thank you :)

Just to clarify - assuming it’s a nitrogen toxicity, did I flush with a low enough ec? I flushed at ec1.0. I could have used plain water but I’m in coco so didn’t want to leave them with nothing in the root zone.

Great thanks :) Will I need to flush another time to be sure to get rid of it?

I was wondering about the RH - I think it’s been inrange butmy dehumidifier’s a bit erratic. I’ll put it on an external fine control setup to stabilise day and night at 60

Yes of course, sorry guys. They’re in coco with canna coco nutrients - A&B, nothing else. The lighting and extraction is fine, but I think my feed was a bit high. I have a background ec of 0.4 and I watered at 1.8ec. I’ve now flushed 2 times pot volume at ec 1.0 to get rid of any toxicity and to...

Hi all, I have this wired plasticky shiny look to the surface of some of my leaves - would anyone know that’s going on?

After taking a cutting from someone else’s room (stupid), keeping it in my propagator and subsequently getting rid of it, some of my plants started to exhibit some markings on the leaves and leaf curling that looks like pictures of cannabis plant viruses I’ve seen on the net. The odd thing is...

Hi, as per the title, I have some weird stippling on the leaves of some, but not all of my seedlings. Could anyone help? They’re in coco using canna coco nutrients at the right levels in a good environment

I’m starting a pheno hunt with a couple of strains. Is it better to keep the original plants that grew from seed as mums or can I use clones taken from those plants as mums? It would be quicker overall to do the latter, but I want to preserve the genetic qualities of the strain as best as possible.

I’m the grower :)

I’m on a mission to raise the quality of my product to as close to top shelf as possible. One of the areas I’m looking to improve is trimming. My trimmers tend to ‘mow’ the buds with the scissors rather than carefully picking out leaf. They also handle the buds a lot, which I’m told is not good...

Thanks, your advice is so appreciated - I’ll just feed water for a week or so as you say & then go a bit easier on the nutrients..

Hi all, I have to flush my soil plants to get rid of extra nutrients in the soil as I have tip burn. I don’t want to compact the soil - they’re in 10L pots, about 5 weeks old (still in veg). I’m thinking of flushing 4L per plant of ph adjusted water. I’m also thinking I should pour the water...

Hi all, I have a problem in my seedling room that I've never seen before - flecks of lighter coloured green on the leaves. After quite a few years of growing a certain strain, I'm finally letting that strain go and am introducing a new strain. I planted the seeds for the new strains 11 days...

Hi all, The Jungle boys mention that letting the plants 'die on the vine' improves the cure process: Link What do you guys think they mean? I'm wondering if this just involves stopping watering the plants for a few days before cropping - or are there other elements to the process that combine...

Hi all. I'm wondering if someone wouldn't mind giving me a couple of recommendations of breeders that I can get modern-style top level strains in seed form, for example exotic genetix, Mid-west grandiflora, capitualator etc. Although the strains look amazing, I'm veering away from exotic...
