Autoflower Week One - Minimal Growth

[Tomcheese]

Second attempt at Autoflowers (might be final). Germinated Dinafem White Widow and Barney's Pineapple Express in shot glass. Planted into Happy Frog (with 30% added perlite) after 24 hours. I know it's not common to transplant, but failed first time starting in a larger pot. Both plants are at 7 days since breaking soil, but seem to be growing slow. More info below, but would love to hear anyone's thoughts on if I should attempt to transplant in the coming days or scrap them completely.

• 125w LED 3500k w/reds (24in up and at 30% light intensity with a dimmer) + two 5000K CFL's (this actually helped them perk up today significantly)
• Schedule: 20/4
• Temp: 75-78
• RH: 58-60%
• Have only watered twice since planting seed - tap water pHd to 6.5

They look fine, maybe lower the main light a bit

I've up potted auto and never an issues

After they get on like 5 node you can up pot

They are stretching for the light.

Also they do a lot under the soil for the first week. But they do seem to be a little slow. what size containers are they in now?

I agree with this.

I agree with this.

Appreciate the quick reply. How low would you recommend? Know that’s hard to tell but hate to burn them. They’re in a 4”x4”x3.5” small pot.

That’s great to hear. I’ll give it a bit of time to repot. Would 3 gal be overkill?

3 gallon is the most common size probably. That’s what I use. You either don’t have enough light or it’s too far away.

I see you’re like 24”. I would try 16 maybe. Keep adjusting it daily or as needed by your plant to maintain that distance.

Does it have a bloom and veg switch? I know some LED lights they recommended keep both on.

This is what I currently have (3500K): https://www.alibaba.com/product-detail/Kingbrite-125W-Pre-assemabled-QB288-led_62137771571.html?spm=a2700.icbuShop.41413.18.19673662cXuzdT

It has a dimmer on it so I had it maybe around 25-30% intensity for the first week. I added two CFLs to add a bit blue spectrum.

I don’t grow with LEDs so I’m no help there.

I would crank it to 100% and try and find the sweet spot. Just my 2 cents
