They r 25 l pots. Never mind. My bust. 25 l = 6.6 gal. Liftable I guess.I would be soaking the entire pot next watering and lift it up. Then wait till it’s way lighter. Then water the same way.
Chart sorry :D:D:DDownload an app to test your light levels asap would be my advice. I'm a newbie myself, also running Mars Hydro but running 2x TSL 2000 in a 4x4 side by side. I'm at a very similar stage, getting ready to top. I have only just finished moving my lights down from 55 to 45 cm. over a week or so, but I'm still only running them at 25%. I've attached a chart I'm using (again, get advice from more experience folk than myself, but most I've shown it to on here are pretty happy with it). I'm in the first week of proper veg (I grew from seed, but considered this the 'clone' period where very little light is needed, my 25% LED's were sitting 36" above during all this). Sat at 10-12 DLI during this phase, have moved up to 25 now, and it moves up to 38 across the coming week. I have an iPhone and the app I use is called Photone. It will instruct you to construct a paper band that wraps around the light sensor at the top of the phone to act as a diffuser, and you will then be able to get readings accurate enough to be useful to you in PPFD, Lux or DLI (one of those is a paid extra, it cost me like $12, paid it in a heartbeat). If you aren't familiar with these measurements, you can still just work off the chart and trust it, or watch some videos from Dr Bruce Bugbee. PPFD or photosynthetic photon flux density is a real measure of the number of photosynthetically useful photons that hit a square meter in a second. It's totally immune to marketing spin, and gets you past this whole, x wattage at y distance turned up to z percent. Each board will be somewhat different, so manufacturer's specs are only so useful, especially when there is a monetary incentive for them to inflate their numbers, which pretty much all do. You should be able to find good PAR maps on sites that do independent testing, to get an idea of the height where you get the most even spread of photons. For the TSL 2000 it's 14 inches, but will vary from light to light. Give yourself the tools to actually know what you're delivering to them rather than gutting it out. :)
