In direct sun? Or under some type of shade cloth? I’m worried that thanking them from t5 to direct sunlight will fry them. Maybe a few minutes at a time at first? I’m usually an indoor guy, so I know I can’t take cuttings from t5s and then immediately throw them under 1000 and the sun is more...

Doing a bit more research, appears full sun is 108,000 lux or 2000 umol. Indoor I’m shooting for 750-900 umol. Am I missing something, or does this simply mean I’ll have a ton of light? Forgive the ignorance, first foray into greenhouse stuff.

Just a thought, if you’re concerned about root development, try switching from t5 (I assume you’re using) to t8. Reduce your light to 20 hours. It’s a similar protocol I use for cuttings to encourage root development. Also, what nutrient profile are you using?

I’m a big believer in the KISS method .. keep it simple... if you’re germinating for soil production the rockwool is not only redundant, it complicates things. Throw it away. If you need further advice on germination protocols, please reach out and I’d be more than happy to share my protocols...

A HUGE thank you!

Great idea, appreciate the feedback. Any idea on PAR/umol for sunlight? I’m sure it depends on region (possibly) but it’s my first transition from indoor so not sure what to expect.

Thanks much! Unfortunately not an option to move in and out. My greenhouse has black out curtains, but even if I black out a portion, based on the movement of the sun there will be times the plants are under direct light. I’m thinking of integrating shade cloth into my SCROG framework directly...

Just curious, is there a particular reason you chose to germinate in rockwool, and then into soil vs germination in paper towel method and then transplant direct to soil when your root is about 3/4 inch long? There’s a ph discrepancy between the two mediums, and I’m wondering if this is...

I’m particularly interested in your experience with hardening off indoor clones from under t5 in aeroponic cloner, to transplanting into RDWC under sunlight. Any advice or previous experience would be appreciated.

Advice anyone? Moving rooted cuttings from aeroponic under t5 to greenhouse. High sun intensity, high UV. Any thoughts on hardening off protocols? Clones will be transplanted into RDWC any advice would be greatly appreciated.

Thank you so much for your replies, and Aquaman, I have read some of your stuff... very informative. This is actually the first forum I’ve ever joined, I have always preferred to be a lurker on othe sites, but needed to join here in order to access the info. Not sure about posting a grow journal...

Finally took the leap to join a forum, and look forward to sharing and learning all things RDWC, with a particular view towards large scale commercial production. Anyone out there doing this?
