Indoor Hydroponic Lettuce Harvest from Ebb and Flow System 31 Dec 2010

[dlevin420]

hey man, looks awesome! quick question, im sure u explain this in an earlier video but this is the only one i have time to watch right now, what species of lettuce is that exactly?

[winterfritz1]

Kind of a disappointment in my Limestone Bibb………I planted it on 12/12, it germinated in 2 days and as of 1/6 it is beginning to bolt. Might have to try another Bibb.

Also, I have some Mazuma growing and it seems to resent being culled but seems to be a good “Canary” regarding salt build up

Looking forward to following your system and such; glad you posted your url at the Blake Seed forum!

Cool stuff; your system is remarkably similar to mine. I have the same fixture but have a mixture of warm and cool T-8’s

Remarkable that you’re moving along the same lines that I am.

Another difference though, is that I use a simple gravity feed, meaning I water the plants by hand from above. I’m using 15-30-10 water soluble fertilizer at ½ strength but intend changing that to a higher nitrogen proportion. Every two weeks I flush the plants (grown in 12 oz Styrofoam cups) with tap water.

Have you noticed any problem with sections of roots dying off after you harvest?

[Stylensky]

That's awesome. Now I'm hungry for a salad.

Would you tell me about water changing?

Think their a little small, I know there doing fine but changes will help.

You can grow lettuce in 1/3 strength but a little slow, 1/2 strength will grow fine.

Full strength can burn and your playing with fire. Biggest mistake new growers do, is maximize nutrients. The plant will only take in what it needs less is better. Also high nutrients can lead to poor stem growth, the plant grows too fast, the light cant catch up, its not as strong as the sun.

Such a cool set up.

you have pythium or root root those roots should be white! looks cool though....hygrozyme will protect your roots from that disease, but changing your reservoir more frequently would also help.

what type of light u use .

[misterhalfwaythere1]

@foryoutocool 6 48" 32W T8 flourescents. 6500K light spectrum. Cheap to buy, cheap to replace, cheap to operate, and nearly perfect spectrum.

I hope my lettuce turns out like yours, I just planted them a few days ago but i am using DWC, any recommendations for what nutrients to use and how much? Right now I am just using a dropper and adding around 2mL of Vegetative nutrients pH around 6.0

@RustyPipez Hey Rusty, thanks for checking it out. I talke about nutes a bit on the blog and will cover them more in the future. Richt now I am using a liquid nutrient at 3/4 strength and it lasts a long time with lettuce. I keep the PH at between 6 and 6.3 and it seems to be about optimum. Check out my other vids as I have built and am growing another great batch in a DWC like yourself. Ebb and flow is great, but DWC is sooo easy.
