Penetrator 345 Wrap Up

ProZachJ — Mon, 20 Dec 2010 20:03:36 +0000

After having grown with the Hydro Grow LED Penetrator 345 for several months now I wanted to provide my impressions on this great grow-light and what it is capable of. From the performance of the test light that we have used it is clear that this light is designed with light intensity for flowering in [...]

LED Roma Tomatoes Week 12-13

ProZachJ — Sun, 26 Sep 2010 01:29:28 +0000

I did some serious pruning today. As the Roma plants end their lifecycle they start to branch excessively and weakly. I pruned down to the strongest vines on each plant. I would like to highlight the similarity to this drawing I posted on GPL before the grow was started What a master of grow planning!

Hey everyone, I wanted to share a few pictures i snapped when i was cutting into the tomatoes we produced using the penetrator light. Zach was out of town, and i didn’t want the tomatoes to get too soft so i decided to see how they chopped up different ways and then i’d put them [...]

LED Roma Tomatoes Week 9

ProZachJ — Wed, 01 Sep 2010 21:03:27 +0000

Still going strong…a couple of lessons learned with these plants. - I have been mixing my base nutrient much weaker and using the CalMg to bring the EC up to desired level. These plants seem to start have BER problems at anything above 2.0 EC. - These things love foliar spray. The more I spray [...]

LED Indoor Roma Tomatoes: Week 4

ProZachJ — Tue, 27 Jul 2010 14:19:01 +0000

I’m so excited about this grow I could hardly sleep last night! Every day the plants just look better and better not to mention the fact that flowers are opening all over the place and we already have a couple baby tomatoes on the vine. Last time I tried to grow these things it took [...]

LED Roma Tomatoes Week 3

ProZachJ — Thu, 22 Jul 2010 02:19:49 +0000

The growth rate of the plants has definitely increased since raising the humidity in the tent and the rolling of the leaves has improved even further (although not completely solved). The plants are still abandoning limbs a little earlier than I would like to see. We are figuring by Monday the plants will be large [...]

Roma Grow Fix?

ProZachJ — Thu, 15 Jul 2010 04:51:00 +0000

So after doing loads of research and asking every growing contact I could think of for help with our Roma grow, I found this article on Urban Garden Magazines Website: Plantworks: Part 1 – Humidity and Vapor Pressure Deficit which included this chart: Low VPD / High RH High VPD / Low RH Mineral deficiencies [...]

Completing the Roma Setup

ProZachJ — Wed, 14 Jul 2010 04:15:19 +0000

So we set out to complete our Roma tomato setup with a scrog screen and some bases to put the powergrowers on. We figured this would be the last change to take the plants out of the tent to do a good nutrient flush so we did that two. I am really happy with the [...]

LED Roma Tomatoes Week 1

ProZachJ — Wed, 07 Jul 2010 00:37:33 +0000

The Romas are growing fast (almost doubled in size the first week) but initially struggled a bit from transplant shock. I am hoping the plants will grow out of their tendency to “roll” their leaves up a couple days after growing them. This condition is known as “Tomato Physiological Leaf Roll” and current research says [...]

LED light Test – HydroGrow Penetrator 345 LED Grow Light

ProZachJ — Mon, 28 Jun 2010 04:43:16 +0000

For a while now I have been saying the UHGU had some big things up our sleeves. Finally, the time has come to unveil one of them. Over the past six months or so, we have been contacted by several LED light manufactures and retailers about endorsing or selling specific LED lights. Our response has [...]
