I guess like all truths, they're only true within certain boundaries. I was trying to say that giving a 2 week old plant 500ppm in the res isn't going to make things move in the direction you might be hoping for! Any more than throwing 1,000 PPFD at it will help to move it out of seedling stage...

Personally I went with Apera Instruments and they even come with pots of calibration solution. I find every 4 weeks ppm will still be accurate +/- 30ppm, and the pH meter is accurate +/- 0.1-0.2

Nutrients - keep it simple. Start with 50% of the recommended dose. I kept it simple with GH Flora Trio - gives you better control over macros. If using RO, you may find yourself needing a little cal mag at some stage in the grow. I tried using liquid silicon, fulvic acid, Canna Rhizotonic...

I did look into Kratky, and I actually think there's nothing wrong with considering it at seedling stage before transfering to DWC (tried it in one of my experiments). However, you'd only want to do that for a short amount of time because the longer the roots when you transplant, the more likely...

Rule #5: (Tied equally with rule #4) Daily diaries aren’t just a ‘nice-to-have’ It’s often suggested that you keep a daily diary. This is usually offered merely as a suggestion, but I’m telling you – for a newbie, it’s essential. Especially if you’re abiding by rule 4. If you’re still...

I’m expecting most finders of this post to respond with a simple TL;DR! In fact it’s so long that I’m having to post it in two parts, as I’ve exceeded the character limit in posts. If anyone is familiar with Myers Briggs personality tests, I’m a classic INTP. This is normally talked about in...

My intention was always for this to be a loft project, but sadly, I just don't have the height clearance... and that's with a 1.6m tall tent. I only intend to live in my house for another year before moving, and either a decent attic or space for a 'shed' are my top priorities. Really want to...

I wasn't sure what a blumat was til I looked it up... doesn't look like it's designed for dwc? Or am I missing something?

Sorry for jumping the gun and misreading what you were saying in your post... as you can gather I'm a total noob, and had no idea bonsai pruning was a growing technique!

First rot was due to trying bennies instead of sterile. Switched to sterile, no more rot. Defoliated heavily so there was less mass for the roots to support... plant bounced back in a week Last weekend, rot returned. I trimmed back the bigger foliage yet again which is why it's still looking...

Thanks for the advice - will just pack it up for now. Was going to do a 48hr dark for transition, and I have Flora Ripen to speed the ending too. It's Legendary OG Punch - supposed to be an 8 week flowerer, which fits my schedule. Thought even if I got half an ounce it would be better than...

Hi folks, Long story short, I've got the in-laws coming to visit mid July. I figured that switching to 12/12 today would give me enough to to complete the harvest (wish I could veg a week or 2 longer), but it leaves me no time to hang, dry and cure. So I had a thought and I have no idea how...

Thanks all. Have a cupboard full of crap I've bought in the last 8 months. Regen-a-root (am pretty sure there's nothing in it, despite hydro shop guy assuring me it was amazing. 1ml/l adds exactly 7ppm, and no perceivable difference to root health). Fulvic acid, which from what I can tell is...

Thanks... I just wondered whether proteins counted as organisms, enzymes being proteins

My worry is - that sludgy root stuff is going to rot out. If the pool shock is enough to stop that turning back into rot which affects everything else again, I'm happy to live with it. If it's better to remove with enzymes so all potential future issues are removed sooner, I'll do that instead...

Thanks. What's left up top is little more than a stump. Most of the large leaves were crispy and dead - there was no way back for them. I've cut back basically to the stem, with just the small internodal leaf sets left off each branch... this is what will form 8 colas - 4 from 4th node, 4 from...

Well, I followed the advice and have gone back to sterile.... made a dilute SB roots bath this morning, left the roots to soak for a few hours, and added approx 3ppm pool shock to the res. I didn't go so far as a full change as it was only changed a couple days ago, and I wanted to make sure it...

Pool shock is what I was recommended, and as weird as it sounds, I always struggled to find Bleach that was just Bleach. In the UK it always seems to contain fragrances/parabens, non-ionic surfectants and thickeners.

Now I have a bigger res, it doesn't seem quite so cumbersome to weigh 0.1g pool shock vs the 0.03g I had to measure last time I ran with it. There's a little more flexibility if I'm +/- 10% of target weight of pool shock now

When I ran sterile, I did pool shock daily (0.03g for size of res I had at the time)... after that was a PITA to manage, I bought silver bullet roots. SB Roots is H202 with silver ions, the silver ions extending the effectiveness of the H202 from 24 hours to up to 2 weeks in veg, and up to 1...
