150W and theyre doing great. introducing them to a harmless dose of 365/400 UVA too from now on, just a hour a day for now, am sure they could take more. going to spread them out a bit.

mine lasted almost the hole grow, so it wasnt bad at all. worked reliable when it worked. when it stopped working (simply stayed white), i pulled it out and felt quite some resistance as if the roots where growing in to it. i soaked it in vinegar (mudballs suggested), it started to go blue again...

at 110W now and theyre going. time to get them to 12/12, tent is full. 12h from 10th on.

plants doing great, went to a 100W today which is a good 300ppfd at the tops. lets hope shes going to take it. temps are a bit low, max 23c, but she dont mind so far. the green is perfect feared the soil is a bit hot, not at all, just right it seems. hope this will keep on a bit.

i also store them in the fridge if i have to store them. the instruction on the label should tell all whats needed to know. good luck.

nematodes work well vs. gnats. also order them from amazon, small pack is below 10 bucks delivered. 15C is optimal storage temp, i would worry more in summer. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4755708/

i guess youre not using any CO2? can only say i also have no luck with 900+, even 800 over a long period is taxing them in my case. you may can make it work, but your plants look like they have quite some weeks to go and the stress signs are a bit early for my taste, would really reduce a bit...

i sounds like you simply disconnect "unused" strips, maybe really try a dimmer so you can dim all your 17 strips. it will be softer light that way and your plants should do better.

you can work with meters if you prefer. you have about a square meter there right? i wonder that your plants cant even take 50W total. i do have some experience usng bridgelux eb3 3000K, while the brand itself as the color temp isnt the problem here. it sounds like a intensity problem yes, but...

so you have a 3x3.5 area and want to blow 480W meanwell eb2 strips on this. minimum youre giving is 5 times 50W or 50W in total ? 50W would be too low, your plant wont show any stres sings for sure. 250W would be too high for this area when you start your plants and want to avoid the problems...

yes, seems so, in commercial gardening they rely still on peat as it gives such consistent reuslts. have he ever mentioned his opinion in regards to organics, like worm casting etc.? btw. his mixes seem to be rich in silica, i think he have mentioned that its important for the cannabioids...

sustee went white today. plants doing fine. tried with a 100W first saw minor stress signs, went down to 85W and all is good.

thank you!

they look great, if they can take it go for it. i have never grewn autos, maybe there is something, if i would grow a auto i would likely also be a bit more stressed with the feeling i need to max her out in veg. ymmv, but if youre after saving some electricity, there is a lot potential to do...

nice to see some results, looking good. what does his updated mix contains? did he went more organic?

yes really, just can speak for myself but its very reproducable, even in different media/fertilzer, near perfect VPD, temps and a very solid CO2 concentration always above ambient. most often using 18/6 for veg. am normally with bugbee too, but am more with chandra here who is saying cannabis...

2 x 120W quantum boards will be well over 500ppfd at the plants. i never had plants taking that much in veg.

thats relative, if you have to choose one language english is likely a good choice and you forced me use a dictionary, that indicates youre good in your language.

i needed to look up presumptuous, your advice and experience is apreciated, just wanted to say there is no shock moment anymore as i watched one for some cycles allready. these sus tee work well so far for me, good to hear it work for others too. pretty hard to be precise in a foregin language...

haha, yes, its my second sus tee i am using so i know that from the previous one. they never wilted even when he was white have to be said.
