So, I've been tying down some branches, in order to create a flat even canopy (early days, but I'm trying to fill a 2.6 x 2.6ft space) with a single plant. After manifolding I've been tying down new shoots left right and centre! My first question is simple: do the ties need to remain...

Hi @Failmore @rkymtnman ... usually when people ask advice round here there's rarely a follow-up with a progress update and a thanks... so... here we are, 6 days later. Res change day tomorrow. The plant did nothing for 3 days then started to live life properly again. I stupidly snapped a node...

I'm a newbie so may be leading up the garden path (my disclaimer)! You seem to have a lot of salt deposits on your pot... could you have a lock out issue? Also, have you got anything on the outside of the net pot stopping light leaking through into your reservoir? Algae can really interfere...

Hi chaps... Happy to report that things have stabilised nicely today. The new leaves have burnt tips, demonstrating clearly that there were too many nutes when first topping to 3rd node, and that 400ppm was still too much thereafter. PPM has increased in the res by 25 since yesterday so...

Very nice looking crop you have there @Failmore! Just dropped ppm again to 250 - I also used a little pump to flush through the hydroton with the res water so the ppm is consistent throughout the tank and media. It also means I've given everything another thorough coating of h202 so have done...

Thank you both for your advice - really appreciated. Only a few hours since I reduced ppms and already I'm seeing some improvement (looking more perky, less like it's gasping for breath). As for the roots... will see what I wake up to tomorrow. Think I said in the last thread I posted that I...

Don't know! Been so paranoid about keeping under 20c that I haven't seen where it would end up without the extra effort!

PPMs stayed constant at 400 for the 24hrs since changing the res, but as @Failmore says, it's such a large body of water for what is currently such a small plant that I'm not sure I'd observe any meaningful fluctuation

After every ice pack use, I dry it, use an antibac spray, wipe again then re-freeze. Unless it's picking something up in the freezer? Maybe I should anti-bac after refreezing rather than beforehand?

@Failmore - 3rd attempt at DWC… 2 previous failures. Failed attempt 1: cheap gear. I bought an eBay ‘oxy pot’. 20l bucket supplied with a 1w pump. The inevitable happened by week 5 (not enough oxygen in root zone). I was using a cheap blurple light too. I should explain, I’m a chemist by...

FYI I've now diluted back to 300ppm. All I did was pH the RO water and add enough SB Roots to ensure no h202 deficit

Base nutes have no silicon or fulvic (hence gh sell both as separate additives). Fulvic is an excellent chelator of micronutrients, doing a better job of making iron absorbable than the artificial chelating agents used in your basic cal/mag (just as one example). Regen-a-root is soluble potash...

I can easily dilute back to 250ppm if even 400 is too much. I was working on the basis that it had 6 main modes before being chopped back to 3rd node then cleaned up.

Hi folks... am starting to get really dumbfounded. I started this plant on bennies. Despite good temps, roots started to rot. So I swapped to silver bullet roots, chopped the dying roots and the plant bounced back well, chucking out a tonne of new roots. I've prepped the plant for a manifold...

Can't keep up with all the amazing advice - thank you all very much... really appreciated. Just got myself a zero water filter system to eliminate source-water contamination as a potential issue, but hadn't considered bacteria. A UV filter isn't too expensive - I might treat the zero water with...

I've been growing for a grand total of 8 months. Maybe I'm just trying to run before I can walk!? Basically, I can only grow one plant at a time given the local laws... otherwise, it's 'intent to supply'. If I mess up an experiment I therefore have nothing to fall back on. Given that all of my...

˄˄˄˄THIS! If molasses, kelp, and other additives are just begging for trouble in DWC, I don't see how any mycorrhizal additives can survive for long with nothing to feed on. And with an air supply keeping a rolling boil going, I don't see how bennies will ever get a chance to latch onto...

Thanks for all your responses... it's a lot to think about. @rkymtnman - I appreciate what you're saying about additives in DWC, but my experience hasn't backed it up. I've kept res at 18-20c perfectly... I have a 25w air pump with a 20l/min ceramic air disc. Only 4 gallons nutes in an 11...

Thats @Frost Spectre - how about growth rate? Have you noticed much of a difference since making the switch?

Hi all I've been determined to get the hang of DWC. I've had multiple failed attempts but thankfully I'm now on the right track. What I've realised (and it's been talked about so often in this forum - can't believe I was arrogant enough to think my inexperienced logic was better than the raw...
