Any tips for us mere mortals while using the HS1? I have found that it can be kep very close during flower about 25cm above the canopy.
I think I have begun to have much better results with these factors:
1) High amount of air pumped into the reservoir, I used 9.2 litres per minute airpump with 4 airstones. That really promotes better root growth
2) Early LST. As early as you dare, just start gradually bending the plant and allow light in to the lower nodes so the growth starts to happen more equally on all sides and you end up with a nice bush. I start usually in the 3rd week.
3) If your plant is completely healthy, start defoliation to let more light in. Start first really easy, like couple of leaves out and let the plant heal for couple days. Repeat as needed. Do not overdo it! Trick is to increase the stress overtime so the plant can handle more without problem. I think I have had really good results because of this
4) Use HS1 at the beginning at 40cm and let the plant grow until 20cm of the lights. Then raise the height of the HS1 along with the plant until it wont strech no more. I think with this one I actually had HS1's more like 10cm to 15cm the very end of the streching phase. That caused that intense Ca defiency you can see. Just supplement more CalMag if you have HS1 really close. Also suppllement with silicone a lot since it helps with the intense light! I remember silicone supplementation also helped with better photosyntesis!
I also use Orca Grow film on my garden walls. That stuff really seems to deliver even though it can be expensive it is good stuff!
5) If possible, keep the relative humidity between 30 to 50 at all times and temperature around 24C.
6) I should note that I used really low EC (max 1.5 while the plain water EC was 0.1) Most of the latter part my EC was only 1.2.
7) Advanced Nutrients. They are simply the best.
I do like to use Canna Rhizotonic for the first couple of weeks at 4ml per litre. That is awesome stuff!
Hope this helps. Everyone's garden is different so I feel quite uneasy to give a general advice about "how to reach maximum crops". I guess most I can say that this is what I think has helped me in my case.
