that's what I figure. and it can't hurt to no harm anyway. Plus it only cost me what? maybe $2.00 in sugar and yeast LOL

I'm about 5 days into 12/12 lighting for lowering on my first hydro grow. The plants are looking good and i'm hoping to have a decent number of females out of the crop once they start to show sex. Anyway... was reading about adding CO2 to the plants but don't have the budget to go buy a big...

roots look great, nice and white. Haven't looked that the lowest part of the stem but around the middle and top it's soft and limp but not mushy. i'm running out on errands but i'll check the lower part when i get back. Damn, this sucks! they were doing so well until yesterday

and this would happen over only one or two days and cause this major of a problem? What do I do in the future to try to avoid this?

not overly hot at all - mid 70's. In fact, it's been cold and damp weather here the last few days so it's actually a few degrees cooler in the grow room than it's been, but nothing drastic, only a few degrees difference

more pics as you can see, the plants o the other tub are fine

working on my first hydro grow and everything was going great until yesterday. I've had my plants vegging for 4-5 weeks. Two nights ago I switched from 24/0 to 12/12 lighting to put them into flowering. Yesterday I switched the nutrient solution from the FoxFarm Big Grow to the FoxFarm Tiger...

well, I do like the idea of faster flowering and increased yield :) Guess I will change the nutrient solution this afternoon afterall Thanks

hmmm, now see, that's why I posted the question.... I've read both ways but never seemed to have found a definite answer which is better...... I suppose it's not absolutely critical one way or the other than

cool, thanks. Will change out the nutrients this afternoon than

I am working on my first hydro grow. Wow, I',m amazed how much better plants grow in hydro compared to soil - much faster and heathier compared to my previous growing "tries" in soil. Any way, they have been vegging for the last 4-5 weeks under a 400w HPS on 24/0 in FoxFarm Big Grow nutrient...

Update: 10/13/09 I just measured my plants and the smallest one is now 18" and the tallest one is about 26". They are growing faster and faster everyday it seems! I was going to wait until Sunday to switch to 12/12 lighting for flowering but now that the smallest plant reached the 18" mark...

At the beginning before the roots really developed I made sure the nutrient solution was high enough to get to the net pots to keep the rockwool wet. Once the roots developed and was hanging down into the solution I figured the level was quite as critical as long as the roots were in the...

thanks, I'll look for his posts. thanks for the tip on getting the old roots out. :)

yep, the roots are very intermingled, you are right. I figure when cutting the males out I'll have to just cut the roots off close to the baskets and let the remaining roots just stay. As far as watering, I've already had to add approx 7-8 gallons to each tote over the last 3 weeks and i've...

yeah, I know I'm going to have to pick up a PH meter soon. Again, after sex shows and I cut out the males i'll have more room. i'll know to figure less plants per tote on my next grow in any case - this is definitely a learning experience.

hi all newbie here, my first posting. i'm not very experienced in growing. I've done 2 small (2-3 plants each) previous grows in soil that turned out "fair" but nothing to brag about to say the least. Wanted to try something different so decided to try hydrophonic growing and without the mess...
