OK auto pilots, what do you think? The top leaves started showing yellow edges about 3 weeks ago. I never had that before, I'm thinking lock out after discovering 2.8 EC run off with 1.4 going in? I finally got it stabilized around 1.2 with .8 going in. Damage is from the top down and still...

I think it's time to ask for help. What's going on here, what have I done? I noticed some bottom leaves yellowing day 15. Sometimes the browning progresses rapidly and they shrivel up. It's progressing upward, but doesn't seem to be accelerating. Day 34 from flip and the tops are really...

Hey guys, I'm about venture outdoors for the first time with White Widow and CBD Compassion Lime from Dutch Passion. How should I start autos for outdoors? I'm thinking of starting inside in something like 1 or 2 gallon pots then transplant into the ground? I have some Fox Farms Happy Frog and...

Mama always said life is like a box of chocolates. You never know what you're gonna get..... when you use bag seed. :wall: The nodes started getting closer and she stopped gaining height a few days back, then I saw couple pistils today. Six weeks from seed, supposedly Girl Scout cookies. I'm...

I'm experimenting with minimal air exchange to keep humidity and temperature up in the winter. No one seems to know how much air exchange is needed, the answers are all over the place and there are always variables. I know from experience that I can use much less ventilation than many/most...

Some say cobs penetrate better, but I've never seen a good explanation of how they can do so. What is the science that explains how cobs can penetrate better? I'm not looking to start a fight, but looking for a better understanding of the penetration topic.

What's the story on shipping these days? After no shipping notice I contacted the seller, he blames covid and says it will ship within a week, about the time it should arrive. Is that bs? I can understand shipping taking longer, but how does covid delay it being shipped and getting a tracking...

Anyone noticed that Trump's daily press conference has turned into two hour campaign rallies? And that they've slid to later in the day to displace the evening news? I boycott them and make sure my TVs are tuned to a different channel.

Just thought I'd throw this up... Bridgelux EB series strips running off an old laptop supply and this dimmer. The frame cost nothing, the strips are simply hung from the top of the cabinet with pieces of 18 ga wire, no heat sinks. Total cost, about $25 for 90w. The cabinet also cost...
