Ahoy, so I've tried out this propagation kit. Beautiful quality, big tick there. BUT, my Seedlings have stretched out badly seeking more light, some to the extent of reaching the lid & then dying. I ended up running all 4 Ionbeam lights (on 10 brightness), which seems to have stemmed the issue (sorry). 16hrs on / 8hrs off. Don't beleive I'm overwatering - made that mistake in the past already. Heat matt on 75deg F.
I'm no expert, and I may have done something else wrong, but that's my experience so far. Any feedback on what I could be doing wrong would be welcome.
