NoHarry What’s up growmies! Kicking off a new run in RDWC. The bean was soaked in water for 24h, and after two days it popped a solid taproot so I put it straight into the hydroton. It’s been stalling for about a week now, but that’s just standard hydro lag while the plant is busy stacking roots downstairs. I’m still hitting it with some semi-organic additives like Canna Rhizotonic for now, but once I do the first res change, I’m planning to go full salts. Wish us luck!
The dimmer on this MedicGrow light is absolute trash and won’t let me drop the draw below 130w, so I had to hang it super high to compensate. The Photone app is showing around 350 PPFD, which is probably overkill for the seedling stage and definitely not efficient.

NoHarry Nothing major happened over the last week. After that initial lag, she started picking up steam toward the end of the week and, predictably, got hungrier for nitrogen. This little gal drank a full liter of the soup over the week. I did a swap, drained 4L and topped off with 5L at N110 (bumping other elements accordingly to keep the ratios dialed in), and gave her a foliar feed with some Hesi Supervit
I wanted to hook up a silent fan, but then I remembered my Spider Farmer clip fan didn't even survive one full run, it's already dead. I’ll have to run a tower fan on low speed for now. The exhaust isn't running yet either.

NoHarry Swapped out another 5L this week with N110, so the res is sitting at roughly N90 right now. I’m planning a full res change, bumping it back to N110, once she bounces back from the stress of topping. She looks just about ready for the snip.

NoHarry Topped her at the start of the week, and she’s been busy pushing out new colas ever since. Noticed a few root strings hitting the bottom of the bucket already. I gave her a foliar spray with some Canna Rhizotonic and added 1ml/L of 3% H2O2 to the res to keep things sterile. Hit her with another topping at the end of the week. Honestly, I’ve always been a bit of a butterfingers, so this stage is easily the most nerve-wracking and crucial part for me.

NoHarry Did I mention I have total ham-fists? LST gives me the worst anxiety-snapped a branch once and it was a total goner, so I’m always paranoid now. Didn't want to push her too hard with the weekly topping, so I kept the nutes locked at N110. By the end of the week, she was definitely showing a deficiency - growth slowed down and the leaves started looking pale. Finally swapped the res to N120 on the last day. Planning to top off with N130 and play it by ear. Next round of topping is happening in a day or two. Still not running the exhaust 24/7 to keep the heat in since it’s been chilly, but no red flags so far.

NoHarry Up to 8 colas today. She’s definitely growing a bit lopsided, but honestly, no real complaints so far. She’s a tank. Thinking about hitting her with one more topping

+Every top-off, I'm adding 1ml of liquid glass (silica) per 10L, plus 25ml of 3% H2O2 per 20L of soup. Looks like she drank about 3L this week, maybe more, the roots are starting to take up so much volume in the bucket that tracking the exact intake is becoming a pain. Still hitting her with Hesi SuperVit as a foliar once a week, no strict schedule though.
